The last month that you can plant green beans and expect a good harvest is probably July. You probably don't want to wait any later than that or else your green beans may not have a chance to fully mature. Starting your green beans indoors is a great way to get them started a few weeks earlier.

Last Frost Date

The average date of last frost is June 15 in Zone 1a. It might get as low as -60°F during the coldest months of winter.

It's important to remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 1a and it can change quite a bit from year to year. Since half of the time in Zone 1a we get a frost after June 15 be ready to cover your green beans in the event of a surprise late frost.
