One of the best tools that you have as gardeners to help us estimate 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.

In Ligonier you can estimate when you can plant stevia by looking at the USDA zone info.

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 fully mature. If you are starting your stevia indoors then you might be able to get away with starting them a couple of weeks earlier.
