You can determine when to plant sutera in Exeter by checking out 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 plants that are more sensitive to the cold.

The earliest that you can plant sutera in Exeter 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. Starting your sutera indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is February 15 in Exeter. You can expect an average low temperature of 25°F in the coldest months of winter.

Keep in mind that the actual date of last frost is not always accurate because it is based on the USDA zone info for Exeter and it will vary from year to year. Half of the time in Exeter you get a frost after February 15 so make sure that you are ready to cover your sutera if you have a late frost.
