Common questions
When should I plant potatoes?
Potatoes are planted as certified seed potatoes (not supermarket tubers) 2-4 weeks before the last spring frost, once soil temperature reaches at least 7 °C; they tolerate light frost in the ground but emerging foliage is killed below -2 °C, so hill soil over any shoots that break through during a late freeze. In zones 9-11 potatoes are a winter or early-spring crop, planted in late January-February to mature before summer heat forces them dormant. Days-to-harvest ranges from 70 days for early/new-potato types to 110-120 days for maincrop storage varieties. 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 potatoes 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 potatoes dates calibrated to that state's climate.
How are these potatoes planting dates calculated?
Each state's dates come from that state's dominant USDA hardiness zone and NOAA average frost dates, then adjusted for potatoes's cold tolerance and days to maturity.
