Plant after danger of frost. Plants can tolerate some light frost, but plants should be transplanted outside whenever daytime temperatures are around 50 degrees. Space plants 24″ apart in rows 3′ apart in fertile soil that has some lime worked into it. Plants often reach 2′-4′ high so plan accordingly. Broccoli may experience trouble with garden pests if planted in the same area year after year, so be sure to rotate planting sites each year. Keep plants well watered as a dry spell can trigger premature heading.

Broccoli culture –
Broccoli is a plant in the cabbage family, whose large, green flower head is used as a vegetable. The stalk and leaves of the broccoli plant may also be eaten. The word broccoli means “the flowering top of a cabbage”. Broccoli is high in vitamin C, as well as dietary fiber and is usually steamed or boiled, but has become popular as a raw vegetable in hors d’œuvre trays. Broccoli closely resembles cauliflower, which is a different cultivar group of the same species.
Harvest the central cluster before it blooms. To tell if the cluster is ready for harvest, rub your thumb over the closed buds on the broccoli head. As long as the buds feel tight, the cluster is still growing. As soon as the buds start to loosen and spread out, cut the cluster with stem attached, using a sharp knife. You should cut the head even if it is small once the buds start spreading as the head will not continue to grow larger once this process starts.
Several days after the central cluster has been harvested, your plant will send out side shoots (smaller versions of the central cluster). These are equally delicious and can be viewed as a second crop. Check plants every 2-3 days and keep cutting shoots regularly. If a plant gets away from you and blooms, it will stop making these side shoots and is finished producing. At this time, you should pull up the plant and place in the compost pile.
