When can I plant Peas in Zone 1a

The USDA Zone info is a great tool for gardeners to help us determine our gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

It's a good idea to determine when to plant peas by reviewing the USDA zone info for Zone 1a.

The earliest that you can plant peas in Zone 1a 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 peas and expect a good harvest is probably July. You probably don't want to wait any later than that or else your peas may not have a chance to really do well. Starting your peas indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

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

Since the USDA zone info for Zone 1a is an average our actual date of last frost can change quite a bit from year to year. Half of the time in Zone 1a there is a last frost after June 15 so be sure to be ready to protect your peas in the event of a late frost.
