One way of estimating when it's possible to plant pea is to look at the USDA zone info for Fergus Falls.

When to plant:	Up to 7 weeks before last frost.

Pea can survive in pretty solid cold which means that you can plant them earlier in the year than more sensitive plants.

The earliest that you can plant pea in Fergus Falls is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant pea and expect a good harvest is probably August. You probably don't want to wait any later than that or else your pea may not have a chance to grow to maturity. If you are starting your pea indoors then you might be able to get away with starting them a few weeks earlier.
