One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. 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 to plant sutera by using the USDA zone info for Richmond.

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 plants that might not handle the cold.

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