The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A way of getting a good idea when it's the best time to plant stevia is to examine the USDA zone info for Buffalo.

Planting Calendar for Stevia

Since stevia do not do well in cold weather it's important to wait until after the last frost has passed before you can plant them.

The earliest that you can plant stevia in Buffalo is May. However, you really should wait until June 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. If you are starting your stevia indoors then you might be able to get away with starting them a couple of weeks earlier.
