One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Sahuarita you can estimate when to plant sutera by using the USDA zone info.

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 slightly earlier in the year than other frost tender plants.

The earliest that you can plant sutera in Sahuarita 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. Any later than that and your sutera may not have a chance to really do well. If you are starting your sutera indoors then you might be able to get away with starting them a few weeks earlier.
