One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The USDA zone info for Zone 2a can be read to figure out when it's the best time to plant green beans.

Planting Calendar for Green beans

Frost tolerance for green beans:	Not tolerant of frost.
When to plant:	After the last frost when the weather gets warmer.

It's probably a bad idea to plant green beans until after the last frost has passed because they are not cold tolerant.

The earliest that you can plant green beans in Zone 2a is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant green beans and expect a good harvest is probably August. 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

In Zone 2a the average date of last frost happens on May 15. In the coldest months of winter you should expect an average low temperature of -50°F.

Keep in mind that USDA zone info for Zone 2a is an average and the actual date of last frost is different every year. Half of the time in Zone 2a there is a last frost after May 15 so make sure that you are prepared to protect your green beans in the event of a late frost.
