Tie outer leaves over the developing head to blanch it and keep it white. Sensitive to temperature swings — heat causes premature bolting.
Brassica napus subsp. rapifera
vegetableA fellow Brassicaceae — similar growing habits to Cauliflower
Start Cauliflower indoors about 6 weeks before your last frost, keeping seeds in cooler soil (around 10–18 °C). Seeds usually come up in around 7 days. Move seedlings out once the danger of frost has passed, in full sun, spaced about 50 cm apart. Expect to harvest in roughly 80 days.
Cauliflower seed rarely stays viable beyond 5 years — track what's still worth sowing.
Water: Medium · Height: 70 cm · Soil: Rich, moist, firm, slightly alkaline (pH 6.5–7.5)
Coccinellidae
The one predator here where the adults hunt as hard as the larvae do.
Aleyrodidae
A puff of white when you brush the leaf, and stickiness underneath.
These three thrive alongside Cauliflower — and alongside each other.
