Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. 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 figuring out when it's possible to plant field peas is to consult the USDA zone info for Pasadena.

When to plant:	Up to 5 weeks before last frost.

Since field peas do well in moderate cold you can plant them a little earlier in the year than other plants that might not handle the cold.

The earliest that you can plant field peas in Pasadena is January. However, you really should wait until February if you don't want to take any chances.

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