You can figure out when it's the best time to plant dahlias in Woodland by using the USDA zone info.

Planting Calendar for Dahlias

It's probably a bad idea to plant dahlias until after the last frost has passed because they require warm weather.

The earliest that you can plant dahlias in Woodland 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 dahlias and expect a good harvest is probably August. Any later than that and your dahlias may not have a chance to fully mature. You can get started a few weeks earlier by starting your dahlias indoors.
