New USDA Zone Map Released

USDA Zone map

The USDA has released their new zone map of the country. The first new map since 1990, and some zones have been changed. Maragret Roach explains the nuances of the changes at “A Way to Garden”.

Out west we use The Sunset Western Garden Zones, which are much more detailed than the USDA zoning, accounting for hills, valleys, and micro-climates. According to Sunset we are in zone 7, while according to the USDA we are in zone 8B.  Seems that always confuses newer gardeners out here.

  1. I don’t bother with the USDA zone map now that I am on the California coast but it is interesting that my fathers zone back in NJ has shifted from 6b to 7a.

  2. We use the A to Z Encyclopedia of Garden Plants here on the North Coast of California as it has tons more photos of plants and I love it’s propagating information. It uses only USDA zones, so it’s good to know Sunset and this one.
