When can I plant Snow peas in Zone 1a

One of the best tools that we have as gardeners to help us estimate our gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

The USDA zone info for Zone 1a should be looked at to determine when it's a good idea to plant snow peas.


Planting Calendar for Snow peas

Frost tolerance for snow peas: Very tolerant of frost.
When you should plant them: Up to 7 weeks before last frost.

Snow peas do well in cold which means that you can get them planted much earlier than other plants that might not handle the cold.

The earliest that you can plant snow 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 snow peas and expect a good harvest is probably July. You probably don't want to wait any later than that or else your snow peas may not have a chance to grow to maturity. Starting your snow peas indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 1a the average date of last frost happens on June 15. In the coldest months of winter we can expect an average low temperature of -60°F.

It's important to remember that our actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 1a and it changes from year to year. Half of the time in Zone 1a we get surprised by a frost after June 15 so always be ready to cover your snow peas in the event of one of those late frosts.
