Sowing and Growing

Sow in place in spring as soon as the weather is consistently warm. Thin seedlings to stand 12-18” apart. If you’re planting indoors, you can sow as early as 6 weeks before the last frost hits, just be sure to use a deep peat pot that can support its long tap root. Fennel can survive some drought, but does better with moderate water, especially when it’s planted in well-drained soil. Germination occurs around 2 weeks from the sowing date.


Snip off leaves anytime for fresh use and drying. Cut off flower heads when fully ripe. Separate and store in a glass jar in a cool, dark spot. The large, deep roots may be dug in spring or fall. This long lived perennial will also reseed itself and can become a nuisance if not controlled. Give it plenty of room and quickly remove unwanted seedlings.
