Zone 3a planting calendar
What to plant in February: zone 3a
A rule-of-thumb starting point for zone 3a: last spring frost around May 30, first fall frost around September 10. 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.
Typical last frost: May 30
Typical first frost: September 10
Winter lows: -40 to -35 °F
Plan & order
- Inventory and order seed3 sowings: Feb 7 and Feb 14 and Feb 21
Sort what you already have, toss anything over 3 years old, and order early while varieties are in stock. Sowing again a few weeks later keeps the harvest coming instead of arriving all at once.
Dormant care
- Sharpen and oil toolsaround Feb 28
Clean, sharpen and oil blades while there's time. Dull tools bruise plants and slow you down.
