How does a cauliflower curd develop?
Cauliflower is a Brassica oleracea cultivar group grown for its compact modified inflorescence. Curds are often white, but orange, purple, and green cultivars also exist. These colors are not automatically signs of spoilage.
Temperature-sensitive development
Cultivars differ in temperature requirements for curd formation. Unsuitable seasons, old or stressed transplants, and interrupted growth can produce small or loose curds. Provide fertile, draining soil and consistent moisture without saturation. Adequate spacing matters. Extra nitrogen alone may not solve failure to head; cultivar adaptation needs checking first.
Blanching and harvest
Some white cultivars benefit from leaf coverage to protect curd color, while others are self-blanching. If leaves are tied, avoid trapping moisture that promotes decay. Harvest compact curds before they become loose or grainy. Cooking and storage behavior vary. Most cauliflower cultivars should not be expected to provide repeated side-shoot harvests like some broccoli varieties.
