Easy-to-grow broccoli bears over a long season. Start seeds indoors 6 weeks before planting time; or buy transplants. In early spring (or in mid- to late summer, for a fall crop), set out plants 15 to 24 inches apart in rows spaced 2 to 3 feet apart.Or sow seeds directly in the garden, spacing them 4 inches apart; thin seedlings to 15 to 24 inches apart.
Harvest 50 to 100 days after setting out plants, 90 to 140 days after sowing. Cut the heads before the buds begin to open. After the central head is harvested, side shoots will produce additional smaller heads.
