The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Edna you can estimate when it's the best time to plant sutera by looking at 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 one of those plants that can tolerate a tiny bit of cold weather you can plant them just a tiny bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant sutera in Edna 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 fully mature. Starting your sutera indoors is a great way to get them started a little bit earlier.

In Edna the average date of last frost happens on February 15. You should expect an average low temperature of 20°F in the coldest months of winter.
