How to prune florence fennel 'romanesco'

Remove flower stalks as soon as they emerge; harvest bulbs when plump, before flowering. Cut or snap emerging flower stems at the base promptly. Remove dead or yellowing fronds with scissors or secateurs. Harvest by cutting the bulb at soil level with a sharp knife, retaining feathery fronds for culinary use.

Bolt removal as needed; one harvest cut per plant. Florence fennel 'Romanesco' forms a large, rounded bulb and has the same minimal pruning needs as other fennel varieties. Bolt control is the priority: remove any emerging flower stalks immediately to preserve bulb quality. Trim yellowing fronds as needed for tidiness. Harvest the whole bulb by cutting at soil level when it reaches tennis-ball size.
