Fennel ‘Mantovano’ (Foeniculum vulgare Miller) is a prized mid-early heritage variety, valued for its vigorous growth and exceptional quality. It produces large, crisp, and aromatic white bulbs (pods) with a hollow stem (“empty cane”), perfect for salads, roasting, or grilling. Its strong aniseed flavour is a cornerstone of Italian cuisine. This variety is known for its reliability and deliciously perfumed bulbs.
🌱 Sow directly Mar-May. Prefers well-drained, fertile soil.
☀️ Requires full sun. Essential for good bulb development.
💧 Water consistently and deeply. Crucial to prevent bolting and ensure juicy, swollen bulbs.
📏 Forms large, plump bulbs. Harvest from the base when bulb is tennis-ball sized.
