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 Monroe you can determine when you can plant pentas by reviewing the USDA zone info.

Planting Calendar for Pentas

Frost tolerance for pentas:	Not tolerant of frost.
When to plant:	After the last frost has passed.

It's probably not a good idea to plant pentas until after the last frost when the weather gets warmer because they are not cold tolerant.

The earliest that you can plant pentas in Monroe 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 pentas and expect a good harvest is probably August. You probably don't want to wait any later than that or else your pentas may not have a chance to fully mature. If you are starting your pentas indoors then you might be able to get away with starting them a little bit earlier.
