Frequently asked questions

What does the 50% last frost date mean?

In half of years the last 32°F freeze of spring happens after this date. It is an average, not a safe date.

What is the safer 10% date?

Only 1 year in 10 has a freeze after this date, so it is the cautious choice for tomatoes, peppers and other frost-tender plants.
