A rule-of-thumb starting point for zone 2a: last spring frost around June 5, first fall frost around August 20. 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: June 5
Typical first frost: August 20
Winter lows: -50 to -45 °F

Turn in compost, cut down cover crops, and let the soil warm two weeks before the first sowing. Sowing again a few weeks later keeps the harvest coming instead of arriving all at once.
