How to use this tool

Your USDA hardiness zone is based on your average annual minimum winter temperature. You can look it up at the USDA Plant Hardiness Zone Map.

Once you know your zone, select it above. For each crop in your zone we show whether it can be direct sown after your last frost date, whether it needs a head start indoors, or whether the season is too short even with indoor starting.
