Broccoli

Broccoli is a cool weather crop. Plant early in the spring, 3 or 4 weeks before the last spring frost date. Plant again 6 to 8 weeks before the first average fall frost date. To harvest broccoli cut the center head when the "buds" are lose but before they open. Rub your thumb across the head if the buds are tight let it continue to grow. As soon as they feel lose cut the head even if it seems small for once the head flowers it will go to seed and stop producing. Depending on the broccoli you planted it should continue to produce "side shoots' on the stem which will  develop  small heads. It will continue to produce until the head goes to seed. If you check and collect every other day you should have broccoli for a good while.
