Florence fennel stands out from ordinary leaf fennel by developing thick, layered pale‑white swollen bulb‑like leaf bases underground. Both the crisp bulb, feathery green fronds and young stems carry a soft sweet anise‑like aroma. The bulb can be roasted, braised, sliced fresh for salads or used as a unique flavour ingredient for side dishes, while delicate fronds serve as fresh garnish. When growing florence fennel, steady moisture is critical; uneven watering easily causes premature bolting before bulbs fully swell. It brings interesting texture and flavour variety for home gardeners who enjoy experimenting with specialty vegetables.
These vegetable‑herb seeds thrive under cool sunny conditions. Extended hot weather triggers early bolting and stops bulb development. Loose, fertile, well‑drained soil promotes plump bulb growth. Avoid over‑rich nitrogen fertilizer which favours leaf growth over bulb formation. Planting Instructions Specifications Botanical: Foeniculum vulgare var. dulce Growth cycle: Approximately 85‑110 days from sowing to bulb harvest Germination rate: ≥78% Storage: Seal seeds and store in cool dry place away from direct sunlight
Planting Guide Choose fully open sunny locations. Prepare loose fertile loam mixed with moderate‑amount well‑decomposed compost, guarantee good drainage. Neutral to slightly alkaline soil pH performs well. Sow in early spring or late summer. Sow directly into garden soil at shallow depth, cover lightly with fine soil. Transplanting should be done with caution, as fennel does not tolerate root disturbance well. Keep 25‑35 cm spacing between individual plants. Optimal germination temperature:15‑22°C; keep substrate evenly moist, germination takes 10‑18 days. Maintain consistent soil moisture, do not let soil completely dry out. Apply balanced low‑nitrogen fertilizer during bulb‑swelling phase. Keep planting area free of weeds. Watch for aphids and caterpillars. Harvest bulbs when they reach full rounded size before flower stalk emerges.
FAQ Q: Why does florence fennel bolt without forming bulbs? A: High temperature, water shortage or root damage will trigger premature bolting; select proper cool sowing time and maintain stable moisture.
Q: Can florence fennel grow in containers? A: It needs deep pots; shallow containers cannot support bulb expansion.
Q: Are fronds of florence fennel edible? A: Yes, feathery green fronds can be used as fresh aromatic garnish for dishes.
Q: Should fennel seedlings be transplanted? A: Direct sowing is preferred; transplant may shock roots and induce bolting.
