Zone 10a planting calendar

What to plant in May: zone 10a

A rule-of-thumb starting point for zone 10a: last spring frost around January 30, first fall frost around December 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.
