USDA Plant Hardiness Zone Map
Input your zip code to find your zone. The city of Pittsburgh will be warmer than outlying areas.

According to the Men's Garden Club of Pittsburgh, the average last hard frost for Pittsburgh is April 20 and for outlying communities, April 30. Because Pittsburgh lies west of the Allegheny Mountains, its gardening climate is often more similar to that of the Midwest than the MidAtlantic, which is tempered by the ocean and not as cold.
