Fennel Germination Information

Fennel Seed Germination How to Sow Fennel:
  • Best sown outdoors after all danger of frost is past in the spring
  • Sow at a depth of 4 times the size of the seeds
  • The seeds can also be sown indoors at 68-72° and at the same depth as outdoors
  • It is difficult to transplant, therefore sow in individual pots
  • Germination will occur in 10-14 days
  • Florence Fennel, F. vulgare var. azoricum, should be sown in early summer and treated as a fall crop

How to Grow Fennel:
Transplanting: Transplant when there are at least two sets of true leaves, being careful with the roots as they resent being disturbed

Spacing: Space 8-12 inches apart

Lighting: Site in full sun

Soil: Site in an alkaline, rich, fertile, dry, well-drained soil. Avoid water-logged soils

Additional Care: Plants may reseed. Florence Fennel needs the cool temperatures of fall for its bulbous leaf base to develop

Appearance and Use:

Grown in borders and culinary gardens alike, this 4-5 foot tall herb is grown for its edible seeds, leaves, and thickened bulbous leaf base. It has thread-like, bright yellow green foliage that resembles dill in appearance but is coarser. Harvest the licorice-flavored leaves at any time for use both fresh and dried. Umbels of yellow flowers are followed by the tan, ribbed seeds. Harvest when they begin to turn brown. Florence Fennel, F. vulgare var. azoricum, grows shorter and has a thickened leaf base, but is otherwise similar. Harvest the celery-like stalks in the fall just before the flowers open. Blanch them by piling soil around them for 2-3 weeks. Eat them raw or cooked
