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.

In Red Oak you can determine when it's the best time to plant sutera by using the USDA zone info.

Since sutera are barely cold tolerant you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant sutera and expect a good harvest is probably August. Any later than that and your sutera may not have a chance to grow to maturity. You can get started a little bit earlier by starting your sutera indoors.
