In addition to knowing about the various growing zones, it is important that you know your area’s last frost date. Every locale has a beginning frost date and a last frost date. The last frost date is the point at which your area is unlikely to receive any additional frosts or freezes.

The National Climatic Data Center is the governmental agency that keeps up with all the climate data.
