What does the weather mean for your garden?
A full forecast — temperatures, rain, wind, radar and maps — plus the part other weather apps leave out: what to actually do about it.
Covers the United States. Forecasts and alerts from the National Weather Service; soil, evapotranspiration and 30-year climate history from Open-Meteo.
Frost, properly
Forecast lows are measured in a ventilated box five feet up. On a clear, still night your plants sit several degrees colder than that — which is how people lose tomatoes on a night the forecast said 36°F. We score the night your plants will actually get.
Water by the numbers
Half an inch of rain in cool weather is a week's supply; the same half inch before a hot windy spell is two days'. We track what the soil lost against what it got and tell you whether to turn the hose on, and how much.
Soil temperature, not the calendar
Seed rots in cold ground. We show soil temperature at seeding depth against what each crop actually needs, and how many days until it gets there.
Heat, wind and disease pressure
Tomatoes drop blossoms above 90°F. Late blight needs cool, wet leaves. Both are in the forecast if you know what to look for — so we look for you.
