Planting Fennel

Young fennel is sensitive to frost, and will do best if planted 6-8 weeks before your first frost date or shortly after your last frost date. Plant seeds 0.5cm (1/4") deep, 10cm (4") apart with 30cm (12") between rows. Fennel prefers rich, well-draining soil, and prefers full sun.

Growing Fennel

Once the seedlings are 3 weeks old, thin them to allow 30cm (12") between each plant. Feeding with a nitrogen-rich fertiliser every 3 weeks after thinning will help with leaf development. Once the bulb begins to develop, heap soil or mulch around it to keep it out of the sun, which will help to keep it flavourful and tender.

Harvesting Fennel

Thinned seedlings have plenty of flavour, and can be used in salads. Leaves can be harvested as needed once the plant is established, being careful to leave enough for the plant to continue growing. Once the bulb reaches 8cm (3") in diameter, gently dig up the plant and cut away from the roots. Trim any remaining leaves 2cm (1") from the top of the bulb.
