Plant several varieties of Brussels sprouts that have different maturity dates at the same time, and harvest in succession.
The less cold-hardy Brussels sprouts varieties are faster-growing, and the more cold-hardy Brussels sprouts varieties are slower-growing.
Each variety will mature in its appropriate seasonal slot from a spring planting. Growers in regions with a long growing season can typically make more plantings of the variety with the longest days to maturity, Diablo.
Varieties are selected for quick growth so they develop full heads.
