Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of figuring out when to plant snap beans is to examine the USDA zone info for Zone 2a.

Planting Calendar for Snap beans

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

Since snap beans require warm weather you need to wait until after the last frost before you can plant them.

The earliest that you can plant snap 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 snap beans and expect a good harvest is probably August. If you wait any later than that and your snap beans may not have a chance to fully mature. If you are starting your snap beans indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

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

It's important to remember that USDA zone info for Zone 2a may not be accurate from year to year 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 snap beans if you have a late frost.
