The first chance to plant peas in Tucson should be figured out by using the USDA zone info.

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

Since peas are one of those plants that can tolerate quite a bit of cold weather you can plant them quite a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant peas in Tucson 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 peas and expect a good harvest is probably October. You probably don't want to wait any later than that or else your peas may not have a chance to really do well. You can get started a few weeks earlier by starting your peas indoors.

Last Frost Date

In Tucson the average date of last frost happens on February 15. You can expect an average low temperature of 25°F in the coldest months of winter.

Keep in mind that the actual date of last frost is just an average because it is based on the USDA zone info for Tucson and it is different every year. Half of the time in Tucson you get a frost after February 15 so always be ready to protect your peas in the event of a late frost.
