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

The first chance to plant stevia in Zone 10b should be estimated by reviewing the USDA zone info.

Planting Calendar for Stevia

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

Stevia require warm weather which tells us that it's necessary 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 10b is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant stevia and expect a good harvest is probably September. Any later than that and your stevia may not have a chance to really do well. You can get started a couple of weeks earlier by starting your stevia indoors.

Last Frost Date

On average all chance of frost has passed is on January 31 in Zone 10b. You can expect an average low temperature of 35°F in the coldest months of winter.

Since the USDA zone info for Zone 10b is not always accurate the actual date of last frost will vary from year to year. Half of the time in Zone 10b there is a last frost after January 31 so make sure that you are ready to cover your stevia in the event of a surprise late frost.
