You can estimate when you can plant stevia in California by reviewing the USDA zone info.

Since stevia are not cold tolerant it is important to wait until after the last frost before you can plant them.

The earliest that you can plant stevia in California 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. Any later than that and 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 little bit earlier.
