Companion planting: Fennel should not be planted near beans, tomatoes, kohlrabi and coriander. Wormwood will stunt its growth so never plant nearby.
Keep track on its growth as it can be invasive.
Likes moist, well-drained soil and full sun.
Perennial. Collect see heads as they form and are still green. Fennel blossom can be collected for its pollen.
