The Allure of Fennel Romanesco

Fennel Romanesco, scientifically known as *Foeniculum vulgare* ‘Romanesco’, is a captivating variety of fennel. Its distinctive beauty lies in its bulb, which features a series of tightly packed, spiraling florets that resemble miniature Romanesco broccoli. This unusual structure adds a touch of whimsy to any garden and makes it a conversation starter.
Beyond its visual appeal, Fennel Romanesco offers a delightful culinary experience. The bulb, when cooked, boasts a mild anise flavor that complements a range of dishes. Its tender florets can be enjoyed raw in salads, sautéed, roasted, or braised. The feathery foliage, known as fennel fronds, adds a delicate anise fragrance and flavor to soups, stews, and sauces.

Choosing the Right Spot for Your Fennel Romanesco

Fennel Romanesco thrives in sunny conditions, requiring at least six hours of direct sunlight per day. Select a location in your garden that receives ample sunlight and has well-drained soil. Fennel prefers a slightly acidic to neutral soil pH, ranging from 6.0 to 7.0.
Before planting, amend your soil with compost or aged manure to enhance its fertility and drainage. Fennel is a heavy feeder, so enriching the soil will ensure its healthy growth.

Starting Fennel Romanesco from Seed

Fennel Romanesco can be started from seed, either directly in the garden or indoors for a head start.
Direct Sowing:

• Timing: Sow seeds directly into the garden after the last frost in spring, when soil temperatures have warmed to at least 60°F (15°C).
• Method: Space seeds 12 inches apart and 1/4 inch deep. Water thoroughly after planting.
• Germination: Expect seedlings to emerge in 10-14 days.

Starting Indoors:

• Timing: Start seeds indoors 4-6 weeks before the last frost.
• Method: Use seed trays or individual pots filled with seed-starting mix. Sow one seed per cell or pot, and cover lightly with soil. Keep the soil consistently moist.
• Transplanting: Once seedlings have developed two sets of true leaves, transplant them into the garden, spacing them 12 inches apart.

Caring for Your Fennel Romanesco

Fennel Romanesco requires consistent care to thrive. Here’s a breakdown of essential practices:
Watering:

• Regularity: Water your fennel regularly, especially during hot and dry weather. Aim to keep the soil consistently moist but not waterlogged.
• Depth: Water deeply, ensuring the roots receive sufficient moisture.

Fertilizing:

• Frequency: Fertilize your fennel every 4-6 weeks with a balanced fertilizer, such as a 10-10-10 formula.
• Application: Apply fertilizer around the base of the plants, avoiding direct contact with the stems.

Weeding:

• Regularity: Keep the area around your fennel free of weeds, as they can compete for nutrients and water.
• Method: Hand-pull weeds or use a hoe to remove them.

Pests and Diseases:

• Pests: Fennel can be susceptible to aphids, leaf miners, and spider mites. Monitor your plants regularly for signs of infestation and treat promptly with insecticidal soap or neem oil.

Harvesting Your Fennel Romanesco

Fennel Romanesco is ready for harvest when the bulbs have reached a diameter of 3-4 inches. The florets should be tightly packed and the bulb should feel firm to the touch.
Harvesting:

• Method: Cut the bulb at the base of the plant, leaving a few inches of stem attached.
• Storage: Store freshly harvested fennel Romanesco in the refrigerator for up to a week.
