Pruning florence fennel — FAQ
When should I prune florence fennel?
Remove flower stalks as soon as they emerge, typically in summer heat. Cut bolting flower stems at their base with clean scissors or snips. Harvest outer fronds as needed. When the central stem begins to elongate rapidly, harvest the bulb immediately rather than trying to delay it.
How often does florence fennel need pruning?
Monitor daily in warm weather; bolt-removal is reactive, not scheduled. Florence fennel is grown for its bulb, so pruning focuses on removing flower stalks (bolting stems) the moment they appear — bolting diverts energy from bulb development and turns the flavour bitter. Snip fronds freely for cooking. Once the plant bolts fully, harvest the bulb; fennel does not regrow usefully after flowering.
