The USDA Zone info is a great tool for gardeners to help us determine 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.

A common way of figuring out when to plant sutera is to use the USDA zone info for Zone 7b.

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.

Sutera can survive in very little cold which tells us that you can plant them slightly earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant sutera in Zone 7b is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant sutera and expect a good harvest is probably August. If you wait any later than that and your sutera may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your sutera indoors.

Last Frost Date

On average the last frost has passed is on April 15 in Zone 7b. You can expect an average low temperature of 5°F in the coldest months of winter.

Since the USDA zone info for Zone 7b is not always accurate the actual date of last frost changes from year to year. Half of the time in Zone 7b you get a frost after April 15 so make sure that you are prepared to protect your sutera if you have a surprise late frost.
