One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. 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 estimating when to plant field peas is to consult the USDA zone info for Spring Grove.

The last month that you can plant field peas and expect a good harvest is probably September. Any later than that and your field peas may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your field peas indoors.
