How to Grow Dianthus 'Salmon' from Seed

Dianthus barbatus, commonly known as Sweet William, is a biennial that brings a delightful splash of color to your garden. To enjoy its blooms next spring, start by sowing the seeds in the summer, around June or July. This timing allows the plants to develop foliage and roots in preparation for next season’s blooms. Late winter sowings (February to March) may flower in their first year.

Start the seeds in seed trays filled with high-quality seed compost. Lightly press the seeds into the soil without burying them too deeply. Keep the soil lightly moist but not waterlogged by watering the base of the tray to avoid washing away the seeds. Place the seed trays in a location with good light but not direct sunlight; a greenhouse or a bright windowsill works well.

Once the seedlings have grown and the end of summer approaches, transplant them to their final location in the garden, spacing them appropriately to allow for full growth. Dianthus 'Salmon' is very easy to grow and requires minimal care. The plants are sturdy and can withstand various conditions, including wet soil over winter.

Biennials like Dianthus fill the gap between spring-flowering bulbs and summer-flowering annuals, adding volume to your garden in late summer and autumn while building strength for abundant blooms next season.
