The USDA Zone info is a great tool for gardeners to help us figure out 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.

The earliest that you can plant begonias in Zone 7b should be figured out by reviewing the USDA zone info.

If you are starting your begonias indoors then you might be able to get away with starting them a couple of weeks earlier.
