Planting Calendar for Sweet Peas

Frost tolerance for sweet peas:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since sweet peas are barely cold tolerant you can plant them slightly earlier in the year than more sensitive plants.

The earliest that you can plant sweet peas in Anderson 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 sweet peas and expect a good harvest is probably September. You probably don't want to wait any later than that or else your sweet peas may not have a chance to really do well. If you are starting your sweet peas indoors then you might be able to get away with starting them a couple of weeks earlier.
