Growing Tips

  • One of the first seeds to sow — they can handle frost.
  • Inoculate with pea/bean inoculant for bigger yields.
  • Provide support early.
  • Pick pods when plump but before seeds bulge.
  • Plant a second crop in late summer for fall harvest in zones 6–9.

Common Mistakes

  • Planting too late — peas hate summer heat above 75°F.
  • Not providing support — even bush varieties tangle without a trellis.
  • Soaking seeds too long — 4–8 hours max, or they rot.
  • Watering overhead during flowering — reduces pollination.

Companion Planting

Companion planting improves growth, deters pests, and makes better use of garden space.
