One of the first steps you take when you are getting a good idea your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A common way of getting a good idea when it's possible to plant stevia is to use the USDA zone info for Zone 12b.

Planting Calendar for Stevia

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

Stevia are not cold tolerant which tells us that it's important to wait until it warms up after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant stevia in Zone 12b is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant stevia and expect a good harvest is probably November. You probably don't want to wait any later than that or else your stevia may not have a chance to really do well. You can get started a few weeks earlier by starting your stevia indoors.

Last Frost Date

In Zone 12b it never frosts. In the coldest months of winter you can expect an average low temperature of 55°F.

Remember that the actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 12b and it can change quite a bit from year to year. Since it never frosts in Zone 12b you do not have to be ready to cover your stevia if you have a late frost.
