USDA zone 9a planting guide

Zone 9a means an average annual winter low of 20°F to 25°F. That coldest-temperature band describes winter cold tolerance. Frost dates and growing-season length come separately from NOAA climate normals.

A typical location in zone 9a sees its last spring frost around March 2 and its first fall frost around November 26. Pick a crop for its zone 9a planting dates, or get dates for your exact ZIP.
