One of the first steps you take when you are estimating 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.

In Kingston you can determine when it's the best time to plant dipladenia by reviewing the USDA zone info.

Planting Calendar for Dipladenia

When to plant:	After the last frost has passed.

It's probably a bad idea to plant dipladenia until after the last frost because they are not cold tolerant.

The earliest that you can plant dipladenia in Kingston 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 little bit earlier.
