Direct-sow pea plants outside Mar 24 – Apr 7 — they shrug off frost.

- Last frost (typ.)
- May 5
In Minneapolis, MN, the typical last frost lands around May 5, and pea plants are cold-hardy — so unlike tomatoes, you don't wait for frost to pass. Sow 28-42 days before the last frost: Mar 24 – Apr 7, as soon as soil is workable and around 45°F.

Why
Cool-season crops get a second season: sow again Jul 27 – Aug 10 for a fall harvest — many gardeners find the fall crop sweeter and less bothered by pests.
- Pea plants germinate in cold soil (~45°F) and tolerate frost that would kill warm-season crops — waiting until after the last frost wastes their best growing weather.
- The 50% frost date is a planning midpoint — for hardy crops an early start risks little.
When this doesn't apply
- Peas hate heat more than cold — late sowings that mature in summer heat produce poorly.
- Cold, waterlogged soil rots seed — 'workable' means it crumbles in your hand, not mud.
