Cauliflower is trickier to grow in some climates than its cousin, broccoli, but the effort is well worth it. And the reward of harvesting a large, attractive head from your garden will give a great sense of satisfaction.
Plants grow best in cool (below 70 degrees F) weather. In most locations it's best to plant it 90 days before the first fall frost so heads will mature during cool weather. Traditional white-headed cauliflowers required gardeners to tie leaves over the developing head to ensure mild flavor and development of snow-white curds. Some newer varieties have outer leaves that naturally cover the head, eliminating the need for blanching. Varieties that develop colored heads of orange, purple, or chartreuse also need no blanching.
how to grow Cauliflower
For types that need blanching, cover the developing head when it is 2 inches in diameter. Harvest the head about 10 days later when it reaches 6-8 inches in diameter. Harvest heads of self-blanching and colored types when they reach full size and before curds begin to separate.
