How, Where & When to Grow Fennel

Although fennel prefers poor dry growing conditions; in its early days, it requires moist fertile drained soil. Best to direct sow in spring, where they are to grow by placing 2 or 3 seeds in a shallow hole, thinning out after suitable conditions allows for successful germination around 7-10 days time. Thin out to one per planting area.


Distance between 2 or more plants must be kept at 50cm to avoid competition for root growth and water uptake.

Regular Care

Plants under stress may bolt pre-maturely; creating smaller plants, so plants must be kept well watered within reason. Weeds must be kept away as they can cause competition for water and nutrients too. Cut down fennel in June if you don't want it to go to seed and it will grow again giving good tasting foliage for longer. Fennel self sows very easily so if you don't want lots of little seedlings make sure all the flowers are removed before going to seed.
