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 estimating when it's a good idea to plant asparagus peas is to examine the USDA zone info for Zone 2b.

Planting Calendar for Asparagus peas

Frost tolerance for asparagus peas:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Asparagus peas do well in a little bit of cold which means that you can plant them a little bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant asparagus peas in Zone 2b is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant asparagus peas and expect a good harvest is probably August. You probably don't want to wait any later than that or else your asparagus peas may not have a chance to grow to maturity. Starting your asparagus peas indoors is a great way to get them started a few weeks earlier.

Last Frost Date
