Gardening Zones in Coronado – 10 & 24

I was confused about gardening zones, but after doing a little research, I have realized that there are two basic guidelines you need to pay attention to: the USDA Hardiness Zone Finder and Sunset’s Garden Climate Zones. The difference is that the U.S.D.A. maps tell you only where a plant may survive the winter; Sunset climate zones show where that plant will thrive year-round. Sunset also takes other factors into account: latitude, elevation, ocean influence, mountains, hills, and valleys.

So…. Coronado zones are 10 (USDA) and 24 (Sunset).
