Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of getting a good idea when it's the best time to plant sutera is to look at the USDA zone info for Seward.

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 do ok in mild cold which tells us that you can plant them a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant sutera in Seward 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. You probably don't want to wait any later than that or else your sutera may not have a chance to grow to maturity. Starting your sutera indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Seward. You should expect an average low temperature of -15°F in the coldest months of winter.

Since the USDA zone info for Seward is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Seward it frosts late in the year after April 15 so make sure that you are ready to cover your sutera if you have a late frost.
