🥬 Brussels Witloof Chicory

What it looks like

Why this variety

Brussels Witloof is the traditional variety for forcing — the finely textured, tightly packed chicon that defined Belgian endive, prized for a delicate, tangy flavor and a texture that stays crisp without turning woody. If you picture a Belgian endive in a shop, pale yellow and torpedo-shaped, you are picturing a Brussels Witloof type.

It is an open-pollinated heirloom, so you can save seed from plants you let flower — unlike the F1 forcing hybrids, which do not come true. It can also be cut young for baby leaf without forcing, but forcing is where it earns its reputation.

How to grow

Sow in fall in Florida, thinning to 8–12 inches apart, and grow roots through winter. Lift roots 1–2 inches thick at the crown, trim tops to an inch, and force in darkness at 50–60°F.

In Florida, witloof is a winter project, not a summer crop: sow in fall, grow the roots through the cool months, lift them in late winter, and force the chicons indoors in a dark, cool spot. Witloof needs 110–130 cool days to make forcing-size roots, and it bolts if planted in warm weather — so the Florida window is fall-sown roots, winter forcing, and no summer attempts. If you cannot give the forcing roots a dark place at about 50–60°F, a cool garage or a spare fridge shelf for the forcing stage is the honest workaround.

Water & feeding

In the garden, witloof wants steady, moderate water while roots size up — about an inch a week, at the base, with mulch to hold it. Do not overfeed: rich, heavily fertilized soil makes forked, hairy roots that force poorly. In the forcing stage, keep the growing medium moist but not soggy, and keep it dark — light is the enemy of a pale, mild chicon.

Common problems

• Premature bolting — warm weather or a late planting sends plants to seed before roots size up. Sow in fall for winter roots, and do not sow witloof for summer harvest.
• Green, bitter chicons — light leaking into the forcing area. Check for light leaks, cover containers completely, and harvest promptly; even brief light exposure greens the heads and sharpens the bitterness.
• Rot in forcing — soggy medium or warm forcing temperatures. Keep the medium moist, not wet, and hold forcing at about 50–60°F with airflow.
• Small roots, small chicons — crowded plants or poor soil. Thin properly, give roots a full season, and lift only roots 1–2 inches thick at the crown.
• Aphids and slugs in the garden stage — blast aphids with water, use beer traps for slugs, and keep the bed weeded so roots grow straight.

Harvest

Force roots for 3–5 weeks until chicons are 5–8 inches long, firm, and pale. Cut just above the crown. A second, smaller flush often follows. Use raw, braised, or grilled, and keep harvested chicons away from light so they stay pale.

Saving seeds

Brussels Witloof is an open-pollinated heirloom, so it comes true from seed — save seed from plants you let flower. The full method is in the Saving seeds section of the Witloof Chicory guide.
