The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Kingman you can estimate when it's possible to plant bidens by using the USDA zone info.

It's a bad idea to plant bidens until after the last frost because they require warm weather.
