Zone 1b planting calendar

What to plant in February: zone 1b

A rule-of-thumb starting point for zone 1b: last spring frost around June 15, first fall frost around August 15. 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.
Typical last frost: June 15
