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 Zone 11a you can determine when it's the best time to plant geranium by referring to the USDA zone info.

Last Frost Date
