Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Seal Beach you can figure out when it's the best time to plant arabis by referring to the USDA zone info.
