Broccoli is an annual cool-season crop hardy to frosts and light freezing, often overlooked and overcooked. Broccoli is sensitive to the heat, if the weather is too hot, it will flower quickly and won't produce an edible head, it tends to grow best in the fall due to the more predictable cool weather. To prevent spreading clubroot and other soil-borne diseases, don't compost brassica roots. Some gardeners won't compost any part of the plant. Also, rotate the placement of brassica plants in your garden so they aren't in the same 10-foot radius for at least 3 consecutive years. Some experts recommend a rotation of 7 years. Headed broccoli is the most common form in the United States, with big central heads closely packed with buds. How to Grow Organic Broccoli from Seed »
