🌞 How to Grow
-
Direct Sow Outdoors: Fennel dislikes transplanting — sow where it will grow.
-
Timing: Sow in spring after the last frost, or in late summer for an autumn crop.
-
Sow ½ inch deep in fertile, well-drained soil.
-
Thin Seedlings to allow space for bulbs to swell.
💧 Care Tips
-
Watering: Keep soil moist, especially while bulbs are forming.
-
Feeding: Enrich soil with compost before sowing.
-
Mulching: Helps retain moisture and suppress weeds.
-
Avoid Root Disturbance: Fennel does best when left undisturbed.
🌼 Growing Sustainably
-
Pollinator Friendly: Umbel flowers attract bees, hoverflies, and lacewings.
-
Multi-Purpose: Every part of the plant — fronds, bulbs, and seeds — is usable.
-
Low Waste: Ideal for zero-waste gardening.
✂️ Harvesting
-
Bulbs: Harvest when they’re firm and tennis ball–sized, before flowering.
-
Leaves: Snip as needed for salads and garnishes.
-
Seeds: Allow flower heads to dry on the plant, then collect and store in jars.
Tip: Mound soil around the base (like leeks) to blanch the bulbs for a sweeter taste.
❄️ Overwintering
-
Hardy in mild regions; in colder climates, treat as annual or mulch heavily.
-
Allow some plants to flower and self-seed for natural regrowth.
