Zone 8b planting calendar

What to plant in July: zone 8b

A rule-of-thumb starting point for zone 8b: last spring frost around March 20, first fall frost around November 25. Zones are set by winter lows, not frost dates, so two gardens in the same zone can be weeks apart. Measure your ZIP below for dates from your area's own 30-year record.

These are zone-average dates. Check an area-level frost estimate from thirty years of nearby weather history and this calendar retimes itself.
