Fennel

Crunchy, anise‑flavoured bulbs (Florence fennel). Likes sun and steady moisture; hot, dry spells can make it “bolt”.

Things to look out for

  • Hot, dry spells can cause bolting — water regularly
  • Give each plant space so bulbs can swell
  • Earth up bulbs lightly to keep them pale

What to sow

Sow outside in shallow lines or start a few seeds in small pots. Keep soil damp. Thin or pot on so plants have space.

UK window: Apr–Jul (direct or modules)

What to plant out

If started in pots, move outside once plants are sturdy and nights are mild. Plant gently to avoid root damage.

UK window: May–Jun

How to care

Water well in dry weather. As bulbs swell, pull a little soil around them to keep them pale and tender.

When to harvest

Cut bulbs when they reach about tennis‑ball size. Use feathery leaves as a herb.
