One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

It's a good idea to determine when it's the best time to plant evolvulus by referring to the USDA zone info for Peru.

Planting Calendar for Evolvulus

Frost tolerance for evolvulus:	Not tolerant of frost.
When to plant:	After the last frost.

Since evolvulus do not do well in cold weather you really should wait until after the last frost has passed before you can plant them.

The earliest that you can plant evolvulus in Peru 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 evolvulus and expect a good harvest is probably August. You probably don't want to wait any later than that or else your evolvulus may not have a chance to really do well. You can get started a couple of weeks earlier by starting your evolvulus indoors.

Last Frost Date

In Peru the average date of last frost happens on April 15. It might get as low as -15°F during the coldest months of winter.

Since the USDA zone info for Peru is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Peru you get surprised by a frost after April 15 so make sure that you are ready to protect your evolvulus in the event of a late frost.
