One of the first steps you take when you are making a decision about 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.

The first chance to plant dipladenia in Deer Park can be determined by referring to the USDA zone info.

Planting Calendar for Dipladenia

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

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

The earliest that you can plant dipladenia in Deer Park 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 dipladenia and expect a good harvest is probably September. You probably don't want to wait any later than that or else your dipladenia may not have a chance to grow to maturity. Starting your dipladenia indoors is a great way to get them started a little bit earlier.
