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 just a tiny bit earlier in the year than other frost tender plants.

The earliest that you can plant sutera in Potsdam is April. However, you really should wait until May 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. Any later than that and your sutera may not have a chance to fully mature. If you are starting your sutera indoors then you might be able to get away with starting them a little bit earlier.
