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

A way of determining when you can plant pea is to refer to the USDA zone info for Wyoming.

Planting Calendar for Pea

Frost tolerance for pea:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Pea tend to make it in pretty solid cold which means that you can plant them earlier in the year than other frost tender plants.

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

The last month that you can plant pea and expect a good harvest is probably September. Any later than that and your pea may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your pea indoors.

Last Frost Date

In Wyoming the average date of last frost happens on April 15. You can expect an average low temperature of -15°F in the coldest months of winter.

Since the USDA zone info for Wyoming is not always accurate the actual date of last frost will vary from year to year. Half of the time in Wyoming last frost occurs after April 15 so make sure that you are ready to protect your pea in the event of one of those late frosts.
