Seed Starting Calendar Chart | When to Start Seeds Indoors

This calendar is based on an average last frost date of May 20. There should be less than a 10% chance of a frost after this date. Before moving plants outdoors on or around May 20, check the latest weather forecast to see if a frost is likely in the next few days. If the predicted low is under 40° F on any of the next few days, it is best to delay moving plants out until the chance of frost has passed. If a late frost is predicted after tender plants have been planted out, protect them with a layer of paper or cloth (not plastic) draped lightly over the plants.
