Transplant time
How long does it take for your seedling to be ready to transplant? As it can depend on quite a lot of variables e.g. temperature, moisture and soil, we display a range.
Please note we don’t display germination times since we prefer transplant time.
Seed to harvest
The time it takes from planting a seed to you enjoying the fruits of your labor (pun intended). As with transplant and germination times, a lot can vary, so we display a range.
Spacing
How far should your plants be apart from eachother? The plant spacing is displayed in either two way.
15 – 20cm; meaning 15 to 20cm in all directions.
5 x 30cm; meaning 5cm between plants and 30cm between rows.
Position
Where do you leave your plants? We try to keep it simple by using terms like full sun, half sun or shade. But what does that mean? Full sun is a minimum of 6 hours of direct sunlight; Partial shade requires about 3 to 6 hours; shade will be okay with less than 3 hours of sunlight.
Hardiness
The minimal temperature your plant can handle. Is the hardy, or not hardy at all? We try to include the minimum temperature it can handle when we have it.
Of course, you can protect plants with fleece so they can still survive below their hardy temperatures.
The timeline
To give you a quick overview of the sowing, transplanting and harvesting dates for each plant, we’ve made the timeline. Please note; the timeline is based on a dutch climate. Zone 8a/8b. If you are growing in a different zone, you may need to adjust the dates to work for you.
If you want to know the earliest date you can start, please look at the general information of all plants where you will find the number of weeks before the last frost date you can start.
To explain the chart, each month is shown by its number; 1 = January, 2 = February, 3 = March, etc.
The light green color represents the time of sowing indoors, a warm greenhouse or heated propagator.
The green color represents the time of sowing outdoors ( when outdoors is shown, indoors is usually also possible)
The darker yellow color represents time to transplant them undercover (in a greenhouse or underneath fleece)
The yellow color represents the time you can transplant them outside
The red color represents the time of harvesting
——— The line seperates the first sowing to the second sowing (like winter sowings)
Please note; the timeline only shows a general overview, the text or blog holds key information about where to start e.g. indoors or outdoors and also things like the hardiness!

General information
Plant now, and harvest for the coming 20 years. Even though the wait is for getting a lot of harvest from asparagus, it’s definitely worth planting them now so you will harvest from your labor for years to come.
You can start asparagus from seed but we recommend buying crowns to give you a head start. If you want to start from seed, it’s best to start them indoors in module trays.
Tips & Tricks
Asparagus should not dry out: So especially in the first year, help them with some extra water when it’s dry.
Support the ferns: They are not that strong, so it’s good to set up a system that supports them.
Easy harvesting: Instead of cutting, snap them off by applying sideway pressure. This way they snap off exactly where they are still soft and you won’t be left with a hard stem when cooking.

General information
Ammi is a great choice for cottage gardens and wildflower meadows and it’s also a popular choice for wedding flowers. Ammi majus or visnaga, also known as Bishop’s flower or Queen Anne’s lace, is a tall and delicate annual plant that belongs to the Apiaceae family.
It is native to the Mediterranean region and has been cultivated for centuries for its delicate and lacy white flowers. The plant typically grows to a height of 1 to 1,5 meters, producing small, white, umbel-shaped flowers that bloom in summer.
Tips & Tricks
Germination: direct sow or surface sow in deep pots or trays and lightly cover. Autumn-sown seeds generally germinate more easily due to temperature fluctuations. If germination does not occur in 2 to 3 weeks move seeds to a colder area for a few days and bring them back indoors. Plant out or repot within a few weeks. On well-draining soil, you can plant autumn-sown plants to overwinter in the garden.
Watering: due to the long taproot Ammi does not require much water once established.
Plant-specific growth tip: Ammi’s cannot be grown in pots because they become very big and they like to root really deep.
Support: Since Ammi’s get really big they will need support! Especially if you are in a windy area.
Pests: Plants can get infected by a number of garden insects but generally require little help from us. Beneficial insects most often solve the problem before plants die due to pests. Ammi is a very strong and vigorous plant.
Cut flower: Ammi can be harvested in late spring and summer. It’s a long-lasting cut flower!

General information
Meet the eggplant, also known as the aubergine or brinjal. This glossy, purple beauty is a member of the nightshade family and is known for its spongy texture and unique flavor.
Eggplants are known for their striking, glossy purple skin, but did you know that they come in a variety of other colors too? While the traditional purple eggplant is the most common, you can also find eggplants in shades of white, yellow, green, and even striped or speckled.
We like to start out our aubergines in mid February. This makes sure they are ready to go outside when the frost is over.
Tips & Tricks
Soil: Aubergines prefer well-drained, fertile soil with a slightly acidic to neutral pH. Adding organic matter such as compost or well-rotted manure to the soil can help to improve its fertility and structure.
Water: Aubergines require consistent moisture to grow and produce fruit. Water deeply and regularly, aiming to keep the soil consistently moist but not waterlogged.
Support: Aubergines can grow tall and require support, especially if they are grown in windy locations. Provide support with a tomato cage or stake the plants when they are young.
Fertilizer: Aubergines are heavy feeders and require regular fertilization to grow and produce fruit. Use a balanced, slow-release fertilizer or side-dress the plants with compost or well-rotted manure.

Growing basil is a fun and easy way to add a delicious and fragrant herb to your home garden. Not only does basil add a fantastic flavor to any dish, but it’s also packed with nutrients and has been used for centuries for its medicinal properties.
Plus, with its bright green leaves and delicate flowers, it adds a touch of beauty to your garden. Whether you’re planting basil in your backyard or in a container on your windowsill, it’s a versatile herb that grows well in a variety of conditions. So, go ahead and give it a try, and before you know it, you’ll be adding fresh basil to all of your meals and enjoying its many benefits.
Tips & Tricks
Sowing: To start basil you need to be on top of warmth. It really flourishes on a heat mat, on a bright window sill or heated propagator. Bonus tip; Sow a bit more seed per cell and thin out to one plant
Soil: When it comes to soil, basil prefers well-drained soil that is rich in organic matter. You can do this by adding vermiculite, perlite or play sand to your mix. It is important to make sure the soil is not waterlogged, as this can lead to root rot.
Water: As for watering, basil should be watered about twice a week. Water the soil directly, avoiding wetting the leaves as much as possible to prevent fungal diseases. It’s important to keep an eye on the weather, as hot and dry weather will require more frequent watering.
Pests: Young seedlings need some protection from slugs and it’s also smart to keep on top of caterpillars. Nothing major, but keep an eye out!
Fertilizer: Although they will flourish when grown in most soils, you could add a balanced fertilizer to help with growth.

General information
Beetroot, you’ve found our personal favorite to grow and eat. Wrap them in tin foil with some honey and thyme and put them in the oven for an hour at 200°C and you will be surprised by how tasty they become!
Beetroot cannot take frost too well, harvest them before the actual frost is here else they will turn woody. Also good to mention getting a boltardy variety so they won’t bolt too easily.
Tips & Tricks
Soil: Beetroot prefers well-drained, fertile soil that is high in organic matter.
Water: Beetroot needs regular watering to keep the soil evenly moist, but not waterlogged. Water deeply about once a week, or more often in hot, dry weather.
Grow them in a clump: Sow 4 seeds per cell of a module tray and let them grow together. This gives more harvest! When sowing in a clump, use the 40-cell size seed tray.
One seed is not one seed: Beetroot seeds tend to clump together a bit, but some don’t germinate and some do so sow a bit extra and cut away what you don’t need.
Storing beetroot: An easy way to store beetroot for up to 3 months is by cutting away the leaves about 2cm above the root and putting them in a zip lock bag in the vegetable basket of your refrigerator. Keep checking them weekly for any mold or rotting, but they store great!

General information
Broad beans, tasty snacks when combined with bacon. They are high on our list to grow every year. Broad beans can tolerate frost to about minus 12 as long as it’s not over a long period. This makes it easy to grow them over winter and get an early harvest!
There are two main varieties to look out for, brown cooking and white cooking, with the brown often tasting a bit more bitter after cooking.
We like to start them in late October and the second sowing round early in the year in February. I must admit that it’s smart to start them in a seed tray because bigger seeds are often a snack for mice.
Tips & Tricks
Water: Broad beans need regular watering, especially during dry periods. Keep the soil evenly moist, but avoid overwatering as this can lead to root rot.
Sunlight: Broad beans require full sun to grow properly, so choose a spot in your garden that gets at least 6 hours of direct sunlight per day.
Support: Broad beans may need support, such as stakes or a trellis, as they grow. This will help them stay upright and prevent the pods from touching the ground.
Pest control: Keep an eye out for common broad bean pests such as aphids, black fly, and slugs, and take steps to control them if necessary.
Fertilizer: Broad beans do not require a lot of fertilizer, but a light application of compost or well-rotted manure can help improve soil fertility.

Are you ready to add some green to your garden? Look no further than broccoli! Not only is it a nutritious addition to any meal, but it’s also fun and easy to grow. With a little bit of sunshine, water, and love, you’ll be on your way to harvesting your very own broccoli in no time. Let’s get growing!
Broccoli and Calabrese are both members of the brassica family and are closely related. The main difference between the two is the time it takes for them to mature. Calabrese, also known as sprouting broccoli, has a shorter maturity time, typically 60-70 days, compared to the typical 70-90 days for broccoli. Calabrese also tends to produce smaller heads, and its side shoots are edible.
Start out your broccoli undercover to make sure they survive. Young plants are really vulnerable to pests.
Tips & Tricks
Plant seedlings at the right time: Broccoli is a cool-season crop, so it’s best to plant seedlings in the spring or fall when temperatures are mild.
Water: Broccoli requires consistent moisture throughout the growing season, so make sure to water regularly and deeply.
Don’t support: As the heads grow, they may become top-heavy. Many gardeners build up support systems to keep it upright. But the broccoli knows what to do, trust the process. It will create its own support if you let it!
Pests: Watch out for common broccoli pests like aphids, caterpillars, and flea beetles, and take steps to control them if necessary. We like to grow them underneath mesh protection.
Give plants enough space: Giving them more space (50cm) will allow for larger heads. So adjust the space based on how big you want your broccoli to be.

Get ready to add some royal color to your plate with our favorite superfood, Purple Sprouting Broccoli! Not only is it a beautiful addition to any garden, but it’s packed with antioxidants and vitamins, making it a healthy and delicious choice for any meal.
It’s important to start purple-sprouting broccoli at the right time. That is not in early spring, but rather in may. This ensures it’s ready to grow to overwinter. When started too early it will almost definitely start bolting.
Pick a spot that you won’t be needing for some time because it takes about 9 months to fully mature and be ready for harvesting.
Tips & Tricks
Water: Keep the soil consistently moist, especially during dry spells or hot weather.
Harvest: You can harvest the broccoli by cutting the main stem and side shoots when they are about 6 inches long and the buds are tight.
Maintenance: Regularly remove any yellowing leaves and spent flower heads to encourage new growth.
Pests: Watch out for common broccoli pests like aphids, caterpillars, and flea beetles, and take steps to control them if necessary. You can do this by adding a crop cover.

Homegrown sweet and tender summer carrots are so much better than store-bought carrots. Rinse the sand off, remove the top and bottom, boil for just a few minutes and they are ready! Carrots are super easy to grow and require very little care. With the right sowing data, you can harvest your first carrots in June and the last in late autumn.
Tips & Tricks
Sowing: Always direct sow carrots because root disturbance causes forked carrots. Select early varieties to sow in early spring. If you want to store carrots over winter select varieties with lower water content. Most seed packages will inform you whether it’s an early spring or summer variety carrot. Sow seeds in a drill that is 1 cm deep and thin them out to one carrot every 2,5cm. For thick winter carrots, you need to thin them out more leaving 4-5cm of space in between.
Soil: It is important to grow carrots in soil that is free of rocks or large clumps. If the carrot root bumps against an object it will fork. Open up the soil with a rake before sowing them.
Watering: Carrots like moist conditions. But be aware of overwatering. If they receive too much water, especially at the end they might start to rot.
plant-specific growth tip: Sow carrots in between rows of leeks to save space.
Pests: Carrot root flies can be a nightmare for your carrots. Cover with a fine mesh in late spring and summer if you had problems with carrot root flies before. Rabbits, slugs and voles can nibble your carrots. If you see damage do not wait for too long to pull your carrots.
Storing: winter carrots can be stored for a month in a cool and dry place. For example in a box of sand or in paper bags. Summer carrots do not store well and are at their best when enjoyed within a week.

Growing cauliflower is not always easy. Timing is essential to get large curds. But once you get the hang of it and see your first proper curds forming you will forget all the failures. Mastering the art of growing cauliflower is like winning an award!
Important to note that the seed-to-harvest time will increase if you decide to grow them over winter but it’s well worth the wait!
Tips & Tricks
Germination: Cauliflower seeds germinate in 4 to 7 days if seeds are kept around 10-15°C. Start seeds in pots or trays to prevent insect damage to seedlings.
Watering: Once plants are established they don’t require much extra water.
plant-specific growth tip: Select the right varieties for specific moments of the year. You can buy more winterhardy varieties to overwinter for an early harvest. We can highly recommend trying the beautiful green romanesco cauliflowers!
Protection before harvest: Once the heart develops they need protection from the sunlight. You can dow this in many ways, the technique used by farmers is wrapping all leaves around the core by folding the leaves and binding them together at the top. You can also take a lower leave from the plant and fold it over the heart.
Pests: Try to always cover your cauliflower. Protect seedlings in early spring with a fleece cover and later in the season with mesh. Keep an eye out for pigeons, caterpillars and slugs. Also, keep an eye out for aphids. You can recognize an aphid attack by new leaf growth curling upwards.

General information
Celeriac, also known as celery root, is a root vegetable that is commonly used in soups, stews, and salads. Despite its popularity, growing celeriac can be a challenge as it is not the easiest vegetable to grow. Celeriac requires cool weather conditions, consistent moisture, and well-drained soil to thrive.
In addition, it has a long growing season and can take up to 120 days to mature, making it one of the slower-growing vegetables in the garden. Even though it’s not easy to grow we can highly recommend giving it a try because they store so well and you can enjoy homegrown celeriac during winter months.
Tips & Tricks
Germination: Celeriac seeds need light to germinate, so don’t add any compost on top. As germination takes approximately 2 to 3 weeks you need to keep on top of moisture in that period to prevent them from drying out. Using a propagator can also increase your success!
Watering: Water them well when transplanting. After that, keep the soil moist, they thrive in those conditions. If you don’t want to use too much water, only give water during dry spells.
Pests: Protect young plants from rabbits! Keep an eye out for aphids, especially in early spring when ladybugs are not yet active in large numbers.

General information
Throughout the world, celery is grown for its thick green juicy stems, fine leaves and seeds. Celery salt for example (seeds and salt ground) is used to flavor cocktails like a bloody mary. Celery leaves are frequently used in cooking. The stems and leaves can be eaten cooked or raw.
Celery can be grown or partially shaded areas but prefers the sun.
Tips & Tricks
Germination: Seeds need light to germinate. Do not cover the seeds with soil after sowing and place them in a light and warm place (15-20℃). Germination should occur within 2 weeks.
Watering: Water them well when transplanting. After that, keep on watering frequently, they love the moist conditions.
Protection: Young plants can not handle frost. Only transplant seedlings after the chance of frost have passed. Celery can get badly affected by blight. Cut away infected parts as early as possible. Some varieties are blight resistant.
Pests: Celaery deals with a few pests, the first being famous in the garden, slugs. To deal with slugs it’s best to get your hands dirty and go to your garden when it’s dark out. You’ll be surprised how many you will find. Also, you can deal with early blight. This will create brown spots, deal with this by removing the affected leaves.

Even though Swiss chard is not as commonly seen in supermarkets compared to other leafy greens, it is relatively easy to grow from seeds. It can also be grown in containers or pots, making it a great option for balconies or smaller gardens. Growing Swiss chard is relatively low maintenance and it can be harvested repeatedly throughout the growing season.
Tips & Tricks
Sowing: Multiple seedlings can emerge from one seed, sow two seeds per cell and thin out to only one or two seedlings per cell. When sown directly space them about 10cm in between plants and 30cm between rows.
Transplanting: When translating from a module tray give them about 25-30cm of spacing in all directions. This gives plants big enough to produce high yields.
Watering: Water them well when transplanting. After that, keep on watering frequently, as they are leafy greens that thrive on water.
Pests: Protect seedlings from slugs. They can destroy all your plants in a single night! Some gardeners need to protect plants with bird netting but we never notice (problematic) bird damage.

Chinese cabbage, this crisp and crunchy vegetable is a staple in many Asian cuisines, adding a delicious and nutritious twist to your meals. With its versatility in cooking and its ease of growth, Chinese cabbage is a must-have in your garden. This hardy plant is well-suited to cooler climates and is a popular choice among gardeners who are looking to extend their growing season.
Please double-check your seed package. Growth recommendations for sowing timelines can vary quite a bit with white cabbages. some take only a few months to harvest and others will take up to 7 months.
Tips & Tricks
Sowing: Seeds germinate fast, within a few days if kept around room temperature. The seedlings grow fast and need to be transplanted in just 4 weeks after germination so don’t sow them too early. When done in spring be sure to harden off plants before transplanting outside.
Watering: This type of cabbage needs a lot of water. So watering twice or even three times a week is advised.
Plant-specific growth tip: Spring sowing is best harvested as small heads to prevent flowering/bolting. Some varieties are more suitable for spring sowing.
*Hardiness: Please note the hardiness for heads is around -5°C!
Pests: Just like any other cabbage it’s best grown under protection against insects. Slugs are your number one challenge so it might be good to set some traps!

Climbing beans are a great addition to create height in your garden giving a more playful look and feel when you are working in your garden.
Tips & Tricks
Sowing: It’s been said that you need to start beans directly at their final spot. We haven’t noticed any growth difference when doing this. Feel free to use a deep seed tray or 9cm pot to germinate your seedlings indoors.
Plant-specific growth tip: Climbing beans need something to climb on, like a trellis, fence, or stake. Make sure your support is sturdy and tall enough to accommodate the plant as it grows. Good to note, they take on a lot of wind, so either pick a good spot or build a sturdy trellis or tippi.
Watering: Keep the soil consistently moist but not waterlogged. Water the plants at the base to avoid wetting the leaves, which can lead to fungal diseases.
Harvest regularly: Harvest the beans regularly to keep the plants producing. Pick the beans when they are young and tender for the best flavor.

Tips & Tricks
Germination: Seeds germinate relatively fast, often within 2 weeks if you can keep the temperature around 16 to 18°C. You can start the seeds in smaller cells and put them into larger pots. After a few weeks, you can continue to grow them in a greenhouse or under a cold frame. Plant out in April or May.
Watering: It’s good to regularly water Chinese asters to keep the soil moist, but don’t waterlog them.
Companion plants: If you grow them in flower beds, combine them with flowers that also require support. For example snapdragons or Phlox.
Support: Since Ammi’s get really big they will need support! Especially if you are in a windy area.
Pests: Plants can get affected by Fusarium Wilt. Rotate the plants every year to minimize the chance of infection. There is also a change of aphids showing up to feast on the plants. You can deal with those with some aphid-repellant spray.
Hardiness: Young plants can handle some cold nights in a greenhouse but the autumn frost kills the plants.
Support: The flower can become very heavy, extra support is needed.

Whether you’re new to gardening or a seasoned pro, zucchini is a reliable and productive crop that’s sure to be a staple in your garden for years to come.
Variety tip: Black beauty F1. When grown on the ground it can reach a total length of six meters and grows about 1 zucchini every three days. Giving you continuous harvest for a few weeks.
Tips & Tricks
Sowing: Sow your seeds undercover and don’t start them too early. They can’t handle any frosts so keep them inside if possible. They germinate quickly and will need to be transplanted before they get rootbound.
Watering: Keep the soil consistently moist, but avoid waterlogging, which can lead to root rot. Water deeply once a week, or more frequently in hot, dry weather.
Trellis system: Zucchini plants can grow quite large and produce heavy fruit, so a trellis or other support may be necessary. Provide a sturdy trellis or stake for the plant to climb on or make them run on the ground through your garden (our preference)
Pests: Zucchini can be susceptible to pests such as aphids, squash bugs, and cucumber beetles. Keep an eye out for any signs of damage and take action if necessary, such as using insecticidal soap or releasing beneficial insects.
Harvesting: Harvest zucchini in an earlier state for extra flavor and texture. Harvest them when they are anywhere from 10 to 15cm for an ideal flavor.

Cucumbers are a refreshing and versatile vegetable, enjoyed both raw and cooked. They are relatively easy to grow and can be a great addition to any home garden. Whether you choose to grow them in a vegetable plot, raised bed, or even in a container, cucumbers are sure to thrive with the right care and attention. With a little effort, you can enjoy a bountiful crop of crisp, juicy cucumbers all season long!
Important to note, there are cucumber varieties with thick, prickly skins so carefully select which cucumber seed you sow.
Second important note, homegrown cucumbers have a tendency to get really bitter. This is due to dry conditions. You can overcome this by watering more regularly and protecting cucumbers from direct sunlight.
Tips & Tricks
Sowing: Cucumbers need warmth to germinate so it’s good to start them undercover. Especially due to the cold nights in April. There are mixed thoughts on transplanting cucumbers into bigger pots. Some say you need to start in 9cm pots, others say, just start them in a small pot and pot them on. Since we don’t like to eat cucumber, we haven’t got a clue who is right. But, to be safe, transplant them early. So don’t let them get rootbound.
Watering: Cucumbers like moist conditions. But most of all they like consistent conditions. Watering regularly can really help with taste and proper development.
Trellis system: Since cucumbers are vine plants we can make them climb by giving them support. A great way to do this is by tying them up with a rope. To attach the rope at the button, bury it underneath the plant when transplanting your seedling. That way the growing roots will keep it in place and you can tie the other end to the top of your polytunnel or greenhouse.
Male flowers: Good to note that some varieties will grow male flowers. You can recognize these by them just growing on a stem rather than on a small cucumber. You need to remove these to prevent pollination. Else you will end up with big (seed-filled) cucumbers which are pretty much unedible.

Timeline
General information
Didiscus or lace flower is a free flowering and easy-to-grow herbaceous plant. Once established it requires little care. The flowers grow tall stems and are great cut flowers. The most common colors are blue-white or soft purple to pink. To enhance bushy growth you can cut the tips out of young plants when they are 30 cm tall. This is also known as pinching.
Tips & Tricks
Germination: Didiscus seeds germinate best when kept dark. You can direct sow the seeds in spring or start seeds in individual cells. If seeds are kept around 20°C you can expect germination within 3 weeks. If your frost-free season is relatively short we recommend sowing indoors because plants need to grow up to 110 days before flowering. Plant out relatively fast or start seeds in a bigger cell or pot so you don’t have to repot early sowing. We’ve noticed plants don’t grow as well when you keep them in smaller cells or pots for too long.
Watering: It’s good to regularly water Chinese asters to keep the soil moist, but don’t waterlog them.
Companion plants: Combine cosmea with marigolds, verbena, basil or nasturtiums. We highly recommend the combination of verbena with cosmos apricot lemonade.
Plant-specific growth tip: Pinching seedlings when they are around 30 cm tall can help to get bushy plants with more flowers.
Support: If your garden is exposed to heavy winds you probably need to give them some support.
Harvesting: Didiscus is a beautiful cut flower or bouquet filler. Pick stems when the first buds are opening and expect flowers to last up to 7 days. The more you cut the more new buds will appear. Can also be dried!

Dwarf French beans, also known as bush beans, are a popular and easy-to-grow vegetable in home gardens. With a compact size and bushy growth habit, they are ideal for small gardens, containers, and raised beds. Dwarf French beans produce a bountiful harvest of tender, flavorful beans in a short period of time, making them a great option for fresh eating and canning. With proper care, you can enjoy a delicious crop of these versatile beans in no time!
The small bush beans are a great addition to your garden since they are so tasty!
Tips & Tricks
Sowing: Don’t start beans out too early. About 3 weeks before the last frost date (under cover) so that you can transplant them once they are ready to go outside.
Watering: Keep the soil consistently moist but avoid waterlogging, which can cause root rot.
Pinching: Pinch off the tips of the plants when they reach 25-30 cm tall to encourage bushier growth.
Harvest regularly: Harvest the beans regularly to keep the plants producing. Pick the beans when they are young and tender for the best flavor. We like to pick them when they are about 10 to 15cm.

General information
Endive, also known as escarole, is a leafy green vegetable that adds a unique, slightly bitter flavor to salads, soups, and sandwiches. Growing endive is not only fun but also rewarding as it can be grown year-round in most climates. It’s a great plant for beginner gardeners and can be grown in pots or in the ground. All it needs is a sunny spot, well-drained soil, and occasional watering. And the best part? You can enjoy the fresh, crisp leaves just a few weeks after planting!
Looking at the timeline, it’s safe to say that when picking the right variety at the right time you can grow endive year round.
A great tip, grow endive together with lettuce, lamb lettuce, and arugula. That way you have a continuous harvest for a salad mix.
Tips & Tricks
Sowing: Sowing fennel can be done starting mid-February indoors. When starting seeds anywhere from mid-April to mid-July use bolt-resistant varieties to prevent early flowering.
Watering: Endive needs to be kept consistently moist, but not waterlogged. Water regularly, especially during dry periods, to ensure that the soil doesn’t dry out.
Pests: Endive can be prone to aphids and slugs, so keep an eye out for these and take action if necessary. Regularly removing any yellowing or damaged leaves can also help prevent pest and disease problems.
Keep on harvesting: If you just pick the outer leaves of your endive you will be able to harvest every week.

Fennel is an aromatic herb that is popular for its delicate anise-like flavor. It can be grown in both warm and cool climates and is commonly used in cooking, salads, and as a medicinal herb.
When transplanting them before your last frost date, protect them with fleece.
Tips & Tricks
Sowing: Sowing fennel can be done starting mid-February indoors. When starting seeds anywhere from mid-April to mid-July use bolt-resistant varieties to prevent early flowering.
Transplanting: Even though it’s been said fennel is related to carrots and parsnips and shouldn’t be started in containers, this doesn’t do much damage since you don’t harvest the root. Not sowing carrots and parsnips in containers is to prevent the root from working which doesn’t matter for fennel. If you are worried about this, you can use a larger pot to start them.
Watering: Fennel doesn’t require much watering. But it’s good to water them in when transplanting and if it’s a dry spell.
Pests: Believe it or not, rabbits are your biggest worry. Protecting them with a fine mesh or fleece will stop rabbits from eating your crops.
Harvesting: You can harvest fennel once they have formed a nice bulb. Just pull them gently out of the soil.

Kale, the superfood of greens, is a powerhouse in both taste and nutrition. With its tender leaves and bold flavor, it adds a tasty and healthy touch to salads, smoothies, and more. Growing kale is easy and rewarding, making it a great choice for any home garden.
What we like most about kale, when planned well, you can harvest it almost year-round!
Tips & Tricks
Sowing: Sowing kale is best done in a module or plug tray. Creating strong separated seedlings to be transplanted out.
Transplanting tip: Start kale in a container to get the most out of the space available. Since they need roughly 6 weeks to form a good seedling. You can save that space in the garden and use them as a second crop.
Watering: Kale doesn’t require much water. Do give them a hand when it’s really dry for a prolonged period.
Pests: The biggest threat to kale are animals like birds and rabbits. Protection with a fine mesh is therefore advised.
Harvesting: The trick with harvesting kale is only picking the larger outer leaves. That way the core can continue to grow and harvesting also promotes new growth.

Leeks, the mild-flavored cousin of onions, are a staple in many a kitchen. With their long, tender stems and delicate flavor, they are a versatile ingredient in soups, stews, and casseroles. Growing your own leeks is a breeze, making them a great crop for both experienced and beginner gardeners.
The most common mistake for leeks is planting them out too quickly. They need 8 to 12 weeks to develop properly before transplanting them.
Tips & Tricks
Sowing: Sowing leeks can be done by starting them in a module tray and after they are done germinating transplant them to p9 pots. You can do this once per pot or multi-sow them to about three per pot.
Transplanting: Leeks are ready to go outside once they are about 20cm high. Remove all compost from the seedling and pop them in a 10cm deep hole. Don’t fill the hole with compost but with water completely.
Watering: Leeks really like moist conditions. So keep them watered well, especially during dry spells.
Pests: Leeks main pests are rust and the allium leaf miner. You can protect your leeks from the allium leaf miner with a fine mesh. Protecting from rust is hard but for looks it’s good to remove the leaves that are affected.
Harvesting: Harvesting can be done throughout summer and winter depending on your variety. If you multi-sow your leeks just twist away the ones that are ready and leave the rest in to grow on.

By far the easiest and most abundant vegetable to grow is lettuce. Due to the large range of varieties you can find lettuce to harvest during almost any month of the year. Once you’ve tasted lettuce from your own garden, you will never go to the supermarket again to get some.
Our personal favorites are the salad bowl red and green, rouge grenobloise and lamb lettuce.
Tips & Tricks
Germiation: Important note, lettuce seeds need light to germinate. Best to just gently press the seeds into the compost.
Sowing: Seeds germinate in low temperatures without a problem. Never use a heat mat for lettuce seeds. Surface sow seeds in a seed tray or in individual cells of a plug tray. Within 5 to 10 days you will see the first seedlings.
Plant specific growth tip: Pick the outer leaves of lettuce (picking) for a continued harvest. Grow different varieties and create your own salad mix! At some point, lettuce wants to flower. Remove plants because quality goes down. It is time for a different vegetable!
Watering: Water them well when transplanting. After that, keep on watering frequently, as they are leafy greens that thrive on water.
Pests: The main pests for lettuce is obviously slugs. To avoid damage keep your garden bed clear and don’t water in de evening. You can also use slug traps or use pellets if you are dealing with a lot of slugs!

Onions are a great addition to any dish and at the same time, they are easy to grow. You can grow them either from seed or from sets.
When grown from seed we recommend the low 40-cell seed tray and also recommend multi-sowing them.
Tips & Tricks
Soil: Onions prefer well-draining soil that is rich in organic matter. They require consistent moisture to grow well, but should not be in soggy soil. So water deeply and regularly (2,5cm per week)
Grow them in a clump: Sow 6 seeds per cell of a module tray and let them grow together. Harvest the first batch when they are the size of green onions and leave about 3 onions to fully mature per clump. This gives a double harvest!
Cover with fleece: Even though onions can tolerate frost, it’s smart to protect them with fleece for fast growth.
Great for storing: Onions can be stored for up to three months when stored properly so take time to learn how to do so.

Parsnip, like carrot, does not like to be transplanted. Sow them directly in a row planting the seed about 0,5 to 1cm deep. Before sowing, break up the topsoil. As they need to be sown directly. Cover them with fleece to help with germination.
Tips & Tricks
Watering: Parsnips don’t need much hand watering as they root very deep. But they like moist conditions so they will thrive when they get some extra when it’s dry.
Skin irritation: Parsnip gives out a sap that might cause skin irritation so it’s smart to wear gloves when working near them.

Peas are a great walk-in-the-garden snack. Imagine you are doing some work in your garden and notice some low-hanging fruit, harvest the pea, and eat it straight away. Peas are famous for not making it to the kitchen.
When speaking of peas I also mean sugar peas, these grow almost to a point the same as peas but there is a separate search result for them.
Starting out your peas can be done either in November when choosing the right varieties but we suggest starting on valentines day (14 February) undercover.
Tips & Tricks
Soil: Beetroot prefers well-drained, rich soil that is high in organic matter. Peas are also nitrogen-fixing plants, which means they can help improve soil fertility by adding nitrogen to the soil as they grow.
Water: Peas need regular watering, especially during dry periods. Keep the soil evenly moist, but avoid overwatering as this can lead to root rot.
Support: Peas may need support, such as stakes or a trellis, as they grow. This will help them stay upright and prevent the pods from touching the ground.
Fertilizer: Peas do not require a lot of fertilizer, but a light application of compost or well-rotted manure can help improve soil fertility.

Get ready to delve into the fascinating world of growing pointed cabbages! These quirky veggies are not only delicious, but they are also easy to grow and make a great addition to any garden. Whether you’re a seasoned gardener or just starting out, you’ll love the satisfaction of watching your pointed cabbages grow from tiny seeds into full-grown, plump heads.
Pointed cabbages are one of our favorites to grow and add to dishes.
Good to note, there are many varieties for spring, summer, autumn or winter growing. Check your seed package and be sure to sow at the correct time for your cabbage.
Tips & Tricks
Sowing: Even though cabbages are hardy you need at least 5°C to get the seeds to germinate, but they germinate best t room temperature so we always germinate them inside.
Watering: It’s important to stay on top of watering, especially during dry spells. The reason is that if they get a sudden hit of water rather than well balanced they might split open in later stages.
Hardiness: Cabbages are really hardy, but if the heads are fully formed they might split open when it gets below freezing. This is due to all the water in the cabbage freezing up.
Pests: Keep an eye out for common pests such as caterpillars and aphids, which can damage the leaves. For the aphids, we found a miracle potion called aphid repellant spray. This works really well and takes care of the problem within a few days. To protect from caterpillars we always grow underneath a fine mesh.
Harvesting: Harvest your cabbages when they reach full size. Cut the head off the plant, leaving a short stub of the stem. You can leave the roots in your soil to decompose, but make sure you cut them off low below the surface else they will regrow.

Potatoes are not only a delicious staple in your kitchen but also a fun and rewarding crop to grow in your garden. From seed potato to digging up your harvest, watch your plants flourish and harvest a bounty of fresh potatoes to enjoy all season long.
You will notice a big difference in seed-to-harvest and spacing. That’s because of the difference between early, second early, and maincrop potatoes. Early potatoes only take 2 months, the second early about 3 months and the main crop 4 months to grow. The same can be said for spacing: 35cm, 45cm and 60cm respectively.
Tips & Tricks
Planting: Potatoes can be planted directly there where you want to grow them. Most important is the depth to plant them, 5cm is enough. We will add more compost once the potatoes are forming to protect them from the sun.
Care: As said above you need to protect potatoes from the sun. If you don’t the parts that get sunlight will turn green and won’t be edible. So once you see the first potatoes forming, grab some compost from your bed and create a trench where the potatoes are growing. You can also do this by adding some extra compost.
Watering: Potatoes usually don’t require much water and will cope well with an average of 2,5cm of rain a week. When harvest arrives it’s good to water extra so they grow bigger.
Protection: Protect early growth from temperatures below 5°C with fleece so that the first leaves don’t freeze.
Pests: As with tomatoes there is a big risk of late blight. This usually happens when there is a lot of rain in summer. To fight this, once you see the first signs of it (brown/yellowing leaves) cut away the entire plant. Don’t confuse it with the normal decaying of potatoes at the end of their growth making the outer stems and leaves turn yellow.
Harvesting: When do you harvest potatoes? The easiest and best way to check is by digging down and seeing how the growth is. But another signal is the yellowing of the plant. You can harvest by just pulling softly on the canopy and life up the potatoes. Get in the soil with your hands to find the rest of the potatoes

Radishes get their heat from the sun. So if you are not into very spicy radishes, sow them in mid-February. If you like them spicy, sow them at the end of April.
Even though radishes are hardy, it’s smart to protect seedlings from the cold wind and frost by adding fleece protection.
Tips & Tricks
Germinating: Germination of radishes in spring should be done inside. Radishes really like heat when germinating. Once they have germinated feel free to move them to your greenhouse or cold frame.
Successive planting: Sow radishes every 2 to 3 weeks for a continuous harvest.
Watering: In order for radishes to swell they need water every two or three days in a dry spell.
Spacing: Even though radishes are fine with growing close to each other they benefit from space. The more space, the bigger they can become. If you sow in a row the spacing of 3cm is fine. If you multi-sow in a clump of three or four seeds, give them 15cm in all directions.

Sowing: To successfully germinate cabbage seeds, a temperature of at least 5°C is required. However, for optimal germination, it’s best to plant the seeds at room temperature indoors.
Watering: Consistent watering is crucial, especially during dry periods. Sudden exposure to large amounts of water can cause the heads to split later on.
Hardiness: Cabbages are tough plants, but fully formed heads may split when temperatures drop below freezing, as the water inside the cabbage freezes.
Pests: Look out for common pests such as caterpillars and aphids that can harm the leaves. To deal with aphids, try using an effective aphid repellant spray. To protect against caterpillars, grow the cabbages under a fine mesh.
Harvesting: Harvest your cabbages when they reach full size by cutting the head off the plant and leaving a short stub of the stem. The roots can be left in the soil to decompose, but make sure to cut them off below the surface to prevent regrowth.

Sowing: Don’t sow salad onion seeds too deep. That might give issues when germinating. Also, water them properly when sowing to start the process.
Cover: Salad onions could use some fleece protection from the cold when sown early. Even though they are hardy, the protection speeds up the growth.
Watering: Salad onions don’t require much attention but watering regularly will produce a better harvest.
Harvesting: Harvesting salad onions can be done by twisting out the ones that are ready. Especially when grown in a clump you can harvest the biggest salad onion and leave the rest in to grow on.

Runner beans are a great addition to create height in your garden giving a more playful look and feel when you are working in your garden.
Tips & Tricks
Sowing: It’s been said that you need to start beans directly at their final spot. We haven’t noticed any growth difference when doing this. Feel free to use a deep seed tray or 9cm pot to germinate your seedlings indoors. You can start them usually when the frost is over in your region. But inside you can start two weeks earlier.
Plant-specific growth tip: Climbing beans require a structure to grow on, such as a trellis, fence, or stake. Ensure that the support is strong and tall enough to accommodate the growth of the plant. It’s important to choose a location that is sheltered from strong winds or build a robust trellis or stake to prevent the plant from being damaged by wind.
Watering: Keep the soil consistently moist but not waterlogged. Water the plants at the base to avoid wetting the leaves, which can lead to fungal diseases.
Harvest regularly: Harvest the beans regularly to keep the plants producing. Pick the beans when they are young and tender for the best flavor.

Whether you’re a seasoned green thumb or a newbie, growing Shallots is a fun and easy way to add some excitement to your gardening life. You can grow them either from seed or from sets.
When grown from seed we recommend the low 40-cell seed tray and also recommend multi-sowing them.
Tips & Tricks
Sowing: Don’t sow shallot seeds too deep, as with any seed, as deep as they are big. since shallot seeds are really small, the just need a light cover.
Grow them in a clump: Sow 3 to 4 seeds per cell of a module tray and let them grow together. The result is smaller but more shallots!
Cover with fleece: Even though shallots can tolerate frost, it’s smart to protect them with fleece for fast growth.
Harvesting: Shallots are ready to harvest when the foliage starts to yellow and fall over. Gently pull the bulbs out of the ground and let them dry in the sun for a few days.

Tips & Tricks
Germinating: Spinach seeds are quite hard, so they need adequate watering before they germinate. You can also let them soak for about 4 hours before sowing them.
Sowing: You can sow them directly outside in rows or, multi-sow them inside in a seed tray. By multi-sowing them 3 or 4 in a clump you get bigger batches to harvest. But sowing them directly is way less work and gives great harvest since they are so easy to grow.
Pests: Most importantly look out for slugs. But if you sow enough, slugs can’t really harm your plants.
Harvesting: Spinach is ready to harvest when the leaves are large and fully formed. You can harvest them regularly by picking the larger outer leaves and leaving the middle intact. That way you will have a continuous harvest.

From planting the seeds to harvesting the colorful peppers, growing these plants is a fun, hard but rewarding experience. With a little bit of care and attention, you can enjoy an abundance of flavorful and nutritious peppers all season long.
Peppers and chilies grow about the same. The main differences are that chilies can be grown closer to each other and they usually don’t require support.
Tips & Tricks
Sowing: Peppers need warmth when germinating. It’s advised to use a heat mat or place them on your warm window sill to germinate. You can also help them by using a propagator.
Transplanting: Don’t transplant them before the last frost date. Peppers can be grown outside, but in our climate, it’s best to grow them in a greenhouse or a polytunnel to get a good yield.
Pests: The only thing to look out for with peppers and chilies are aphids. If you see them, just wash them off and rub your hands over the leaves to clear them from those buggers.
Clear new growth: Once we near the end of august it’s smart to clear the plants of new flowers or fruits. This way the energy can be funneled towards the fruits ripening.
Harvesting: When does one harvest peppers? They are ready to pick once they are a shiny darker shade of green or if the first color starts to appear. If you want fully mature fruits, it can take up to a month to ripen completely.

Get ready to get your hands dirty and watch your hard work pay off because it’s time to learn all about growing delicious, plump ears of corn! From planting the seeds to harvesting the golden ears, growing corn is a fun and rewarding experience. So grab your gardening gloves and let’s get started on growing our own little piece of farm-fresh heaven!
Corn is one of those crops that is easy to grow but hard to protect. They tolerate a lot, but you have to harvest before the crows do! Some bird netting is advised but can be hard due to the height of the plants.
Tips & Tricks
Sowing: You can pre-sow them undercover from mid-April or sow them directly outside on the last frost date. Sow them about 1cm deep. Since they need two days at 10°C to germinate it might take some time before they do. It’s good to protect them with fleece if you do decide to sow them directly outside. This prevents the birds from eating the seed and keeps the soil warm.
Transplanting: Don’t transplant them before the last frost date or if the weather forecast is no more frost. They will not tolerate any frost since they are sun-loving vegetables.
Position: Important to note that corn needs 6 to 8 hours of sun as a minimum.
Pests: As said above, the crows are your biggest worry.
Watering: Corn does require about 2,5cm of water each week. Either from rain or irrigation. So it’s good to assist in dry spells. Some extra water is advised once the ears are swelling.
Grow in blocks: Corn is self-pollinating, meaning the fluffy seed-looking tops drop pollen down onto the tip of the cob. In order to get good pollination, place your corn in a block instead of a row. Three by three is enough to get great pollination rates.

Bonus tip: Prune your tomatoes. In the arm pits if you like new stems will grow. Pinch them out to prevent a bush forming.
Tips & Tricks
Sowing: Don’t, Don’t, Don’t start them TO EARLY. I know you want to sow your tomatoes, but sowing them in February or early march will just give you large plants that have no space and need to go outside even though there is still frost. Start them at the end of March and you will be rewarded with perfect seedlings at the right time.
Transplanting: It’s important to transplant your plants deep. Leaving only the leaves above the soil. Every little hair on the stem of a tomato will grow new roots. This is because it’s actually a vine plant.
Pests: We all know of Phytophthora, also known as blight or potato disease. It’s almost impossible to keep it off your plants. But a good way to keep any disease of tomatoes is by keeping the leaves dry and watering at the root level. Also, avoid water splashing up to your plant.
Watering: When transplanting, water them very well. Then don’t water for 1 or two weeks to help the roots develop. After that, it’s good to water twice or three times a week averaging about 2,5cm of water. Don’t water a lot at once because that will make your tomatoes burst open.
Care: Keep on removing the lower leaves. The lower leaves don’t help with the growth of the plant and are more prone to pests and diseases.

Please double-check your seed package. Growth recommendations for sowing timelines can vary quite a bit with white cabbages. some take only a few months to harvest and others will take up to 7 months.
Tips & Tricks
Sowing: To successfully germinate cabbage seeds, a temperature of at least 5°C is required. However, for optimal germination, it’s best to plant the seeds at room temperature indoors.
Watering: Consistent watering is crucial, especially during dry periods. Sudden exposure to large amounts of water can cause the heads to split later on.
Hardiness: Cabbages are tough plants, but fully formed heads may split when temperatures drop below freezing, as the water inside the cabbage freezes.
Pests: Look out for common pests such as caterpillars and aphids that can harm the leaves. To deal with aphids, try using an effective aphid-repellant spray. To protect against caterpillars, grow the cabbages under a fine mesh.
Harvesting: Harvest your cabbages when they reach full size by cutting the head off the plant and leaving a short stub of the stem. The roots can be left in the soil to decompose, but make sure to cut them off below the surface to prevent regrowth.
