Tips to grow to germinate yarrow (Achillea) seeds

No need to stress; it's a piece of cake. Keep the soil consistently moist but not overly wet, and don't bury the seeds too deeply under a heavy layer of compost. To keep things simple and ensure success, go for a small to medium-sized pot or seed tray with cells measuring around 3 to 4 cm. After a few weeks, you can transplant these young seedlings into your garden. If you want them to be a bit sturdier, consider transplanting or potting them up once – especially if your garden has its fair share of hungry wildlife. Remember, bigger plants are hardier!

When to pick the flowers

For the longest vase life, pick the stems when the florets start to open. If you prefer dried arrangements, hang the stems upside down in a dark room. If the flowers or stems start to look a bit droopy, you may have picked them a bit too early. Keep the water fresh by removing foliage from the base of the stem. With proper care, you can enjoy these vibrant blooms for up to a week.
