One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A common way of making a decision about when it's possible to plant sutera is to look at the USDA zone info for Peru.

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 do ok in moderate cold you can plant them just a tiny bit earlier in the year than other plants that might not handle the cold.

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

Last Frost Date

The average date of last frost is April 15 in Peru. In the coldest months of winter you should expect an average low temperature of -15°F.

Keep in mind that the actual date of last frost is not always accurate because it is based on the USDA zone info for Peru and it is different every year. Half of the time in Peru there is a last frost after April 15 so make sure that you are prepared to protect your sutera in the event of a late frost.
