One of the best tools that you have as gardeners to help us determine 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 Dover you can estimate when it's possible to plant evolvulus by using the USDA zone info.

When to plant:	After the last frost when the weather gets warmer.

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

The earliest that you can plant evolvulus in Dover 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. Any later than that and your evolvulus may not have a chance to really do well. Starting your evolvulus indoors is a great way to get them started a little bit earlier.
