The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

It's a good idea to figure out when it's a good idea to plant sutera by looking at the USDA zone info for Concord.

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 are barely cold tolerant which means that you can start planting them slightly earlier than more sensitive plants.

The earliest that you can plant sutera in Concord 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 grow to maturity. Starting your sutera indoors is a great way to get them started a few weeks earlier.

Last Frost Date

In Concord the average date of last frost happens on February 15. It might get as low as 25°F during the coldest months of winter.

Since the USDA zone info for Concord is not always accurate the actual date of last frost is different every year. Half of the time in Concord there is a last frost after February 15 so make sure that you are prepared to cover your sutera if you have one of those late frosts.
