When to plant Fennel in Leeds

Sow seeds thinly around 10th April - 8th May on a fine, raked seedbed, then cover with only a light dusting of soil. Keep the soil just moist during germination. Sow a fresh batch every 21 days for a longer picking period.

When seedlings are large enough to handle, thin them so each plant has room to make a strong root. Keep the best seedlings and remove the rest cleanly to avoid crowding from 24th April to 5th June.

Direct-sown fennel needs no transplanting. Once the seedlings are established, thin them to 30 cm apart in full sun and free-draining soil, and use a cloche or fleece if cold weather returns around 8th May - 24th June.

Keep plants evenly moist from 8th May to 2nd November, especially in dry spells, but do not leave the soil soggy. Pinch out the growing tips regularly so the plants stay bushy and are less likely to bolt.

Pick young leaves from 3rd July and keep cutting little and often to encourage fresh growth. Leave some plants to flower for seed, then collect ripe heads through 2nd November once they turn brown and dry.
