For spring plantings, seed or set transplants 2 to 3 weeks before last spring frost date. If you transplant, calculate 10 less days for ripening or the “days to maturity.”For fall plantings, seed 85 to 100 days before your average first fall frost date. If you live in a warm place, a fall planting is best, as broccoli thrives in cool weather. Plant seeds in mid- to late-summer in most positions.Plant seeds ½ inch deep.Within a row, space your plants 12 to 24 inches apart with 36 inches between each row.You will need to thin seedlings to 12 inches apart to give room for the broccoli to fix.
