The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of determining when to plant dipladenia is to refer to the USDA zone info for Clemson.

Planting Calendar for Dipladenia

Frost tolerance for dipladenia:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

It's a bad idea to plant dipladenia until after all chance of frost has passed because they do not do well in cold weather.

The earliest that you can plant dipladenia in Clemson 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 dipladenia and expect a good harvest is probably August. Any later than that and your dipladenia may not have a chance to really do well. Starting your dipladenia indoors is a great way to get them started a few weeks earlier.

Last Frost Date

On average the last frost has passed is on March 15 in Clemson. It might get as low as 10°F during the coldest months of winter.

Since the USDA zone info for Clemson is not always accurate the actual date of last frost is different every year. Since half of the time in Clemson last frost occurs after March 15 be ready to protect your dipladenia if you have a surprise late frost.
