Common questions
When should I plant tomatoes?
Wait until soil has warmed to at least 16 °C and night temperatures stay above 10 °C. Tomatoes set fruit poorly below 13 °C at night and stop above 32 °C, which is why hot-zone gardeners run a spring + fall crop instead of one long summer. 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 tomatoes 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 tomatoes dates calibrated to that state's climate.
How are these tomatoes planting dates calculated?
Each state's dates come from that state's dominant USDA hardiness zone and NOAA average frost dates, then adjusted for tomatoes's cold tolerance and days to maturity.
