The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Erie you can estimate when it's the best time to plant crassula by reviewing the USDA zone info.

Planting Calendar for Crassula

Frost tolerance for crassula:	Not tolerant of frost.
When to plant:	After the last frost.

It's probably not a good idea to plant crassula until after the last frost has passed because they are not cold tolerant.

The earliest that you can plant crassula in Erie 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 crassula and expect a good harvest is probably August. You probably don't want to wait any later than that or else your crassula may not have a chance to fully mature. Starting your crassula indoors is a great way to get them started a little bit earlier.

Last Frost Date
