The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Groves you can estimate when to plant dahlias by using the USDA zone info.

Since dahlias do not do well in cold weather it's necessary to wait until after the last frost before you can plant them.

The earliest that you can plant dahlias in Groves 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 dahlias and expect a good harvest is probably September. Any later than that and your dahlias may not have a chance to grow to maturity. If you are starting your dahlias indoors then you might be able to get away with starting them a little bit earlier.
