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 Edinburgh you can estimate when it's a good idea to plant chard by referring to the USDA zone info.
