Choose the Best Regional Version of the Gardening by the Moon
To select the best regional version for your local climate, you should know your average frost free dates. Remember, average means that frost will occur up to fifty percent of the time before or after this date. It is not the last possible date of frost.
Frost is also effected by the proximity of water, wind shelter, altitude, and microclimates. These are the approximate areas recommended for each of our different versions. Speckled areas may require some adjustments of planting dates due to extremes of altitude, temperature or humidity.
Other ways to find your frost dates:
- Ask your neighbors, they may know about microclimate effects in your area
- Consult the local agricultural extension or master gardeners program
- Search weather.com to find weather data by zip code (US only). Type in your zip code, weather related to Lawn and Garden, and look for Monthly Averages and Records.
Below is a map of the USDA average last spring frost dates that will give you general guidelines.
