Pest management: Cauliflower cultural tips, pests, and diseases
The Basics
When to plant: Transplant into the garden Feb–Apr, Sep (maybe Aug or Oct). Plants are ready to transplant 8 weeks after seeding.
Harvest window: Harvest when the heads are of good size, usually 5 to 6 inches in diameter and still compact.
Care overview: As the heads enlarge, they may become exposed to the sun and discolor. Avoid this by folding the leaves over the heads or by typing the leaves together to protect the developing curd from the sun.
