Common questions
When should I plant brussels sprouts?
Brussels sprouts are a long-season crop — transplant outdoors 2–3 weeks before the last spring frost once seedlings are 10–15 cm tall, or start a fall crop by counting back 90–100 days from the first fall frost and setting transplants then. Flavour sweetens after the first hard frost (below -2 °C), making them one of the few vegetables that actually improves with autumn cold. Zones 9–10 can grow them as a winter crop but the lack of hard frost reduces flavour development. Because the right window depends on your local frost dates, pick your US state above for a calendar with exact sow, transplant, and harvest dates.
Does the best time to plant brussels sprouts vary by state?
Yes — planting dates swing by several weeks across the US because each state sits in a different USDA zone with its own frost window. Every state page here gives brussels sprouts dates calibrated to that state's climate.
How are these brussels sprouts planting dates calculated?
Each state's dates come from that state's dominant USDA hardiness zone and NOAA average frost dates, then adjusted for brussels sprouts's cold tolerance and days to maturity.
