About Florence Fennel 'Zefa Fino'

Foeniculum vulgare var. azoricum 'Zefa Fino' · also called Zefa Fino fennel, bulb fennel · edible

'Zefa Fino' is a bolt-resistant Florence fennel grown for its swollen, crisp white bulb of overlapping leaf bases with a sweet aniseed flavour, topped by feathery edible fronds. The bred-in bolt resistance suits cooler and variable climates. Sow after midsummer, keep it growing steadily, and earth up the bulbs as they swell.

Ideal humidity: Ambient outdoor

Watch for — Bolting before bulbing: The most common failure: early sowing, cold checks, transplant shock or drought trigger flowering before the bulb forms. Sow after midsummer, sow direct or with minimal root disturbance, and never let plants dry out.

The watering schedule, season by season

Florence Fennel 'Zefa Fino' crops best on deep, regular soaks rather than light daily sprinkles — steady moisture at the roots is what fills and sizes the harvest. The base rhythm for florence fennel 'zefa fino' is every 3-5 days; never let the soil dry out, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Florence fennel is thirsty and bolt-prone: any drought check makes it run to seed before bulbing. Keep the soil consistently moist with regular, even watering, mulching to conserve moisture in warm spells.
