Enter your average last spring frost date and first fall frost date, and the calculator returns the number of frost free days in between, which is your effective growing season. It also suggests a safe outdoor planting date a buffer of days after the last frost, since a late cold snap can still nip warm season plants like tomatoes, peppers and basil. Knowing the season length tells you whether a long maturing variety has time to ripen, or whether you should choose a quicker one.
