Why Grow It
A delicious, white, aniseed-flavoured bulb that will be ready to eat in four months. Worth growing for its pretty foliage alone. It’s a little tricky to grow, but definitely worth a try.
Sowing
- Florence fennel is a Mediterranean crop that needs warm growing conditions, so it should be grown in the summer.
- If exposed to fluctuating or low temperatures it will be at risk of bolting.
- Florence fennel can be sown in modules for later transplanting or directly into soil.
- If sowing in modules, sow one seed per module from late April to July.
- If sowing direct, sow from late May till July, 1cm deep, thinly, in rows 30cm apart.
Growing
- Plants will be ready for transplanting when they around 10-15cm high.
- Space 30cm apart in rows 30cm apart and thin direct sown crops to the same spacing.
- Don’t allow the soil to dry out as this can encourage bolting
- Florence fennel will grow in any reasonably fertile soil.
Harvesting
- Expect bulbs to be ready 14-16 weeks after sowing (the bulb should be 7cm across).
- Cut the bulb off at ground level. Further, feathery shoots will appear, which can be used as celery/dill-flavoured seasoning in the kitchen.
- Snip the leaves off the bulb – if you leave them on, they draw the moisture out of the bulb.
TIPS
- Urbanites rejoice, for fennel can be grown in 13cm-deep pots.
- The bulb, the celery-like stalks and the feathery leaves can all be eaten.
Problems
- Slugs are a problem at seedling stage. For more info on dealing with pests click here.
