USDA zone 6a planting guide

Zone 6a means an average annual winter low of -10°F to -5°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 6a sees its last spring frost around April 29 and its first fall frost around October 16. Pick a crop for its zone 6a planting dates, or get dates for your exact ZIP.
