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.

One way of determining when it's a good idea to plant sutera is to refer to the USDA zone info for Calipatria.

Planting Calendar for Sutera

Frost tolerance for sutera:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since sutera are barely cold tolerant you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant sutera in Calipatria 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 sutera and expect a good harvest is probably September. You probably don't want to wait any later than that or else your sutera may not have a chance to grow to maturity. If you are starting your sutera indoors then you might be able to get away with starting them a few weeks earlier.

Since the USDA zone info for Calipatria is not always accurate the actual date of last frost changes from year to year. Half of the time in Calipatria there is a last frost after February 15 so always be ready to cover your sutera if you have a surprise late frost.
