One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

It's a good idea to estimate when it's a good idea to plant stevia by looking at the USDA zone info for Concord.

Planting Calendar for Stevia

Frost tolerance for stevia:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

It's a bad idea to plant stevia until after the last frost when the weather gets warmer because they require warm weather.

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