Like most of the brassica (cabbage) family, broccoli is best grown as a cool weather crop. As it matures fairly quickly, broccoli is often a 'double' crop for spring and fall. Although broccoli can be direct sown, best results are often from starting indoors, for both early and late crops. For early, plant 1/4 inch deep 5-6 weeks before transplanting, generally around time of last frost. For late, start early to mid summer, timing crop to mature before cold weather. Broccoli needs a rich soil and consistent moisture. Best germination is at soil temperatures of 60-75 F.
