Pea

Pisum sativum · Vegetable

A cool-season climber and one of the first crops to sow each year. Peas dislike heat, so timing matters more than anything else. Freshly picked pods are far sweeter than shop-bought, and the plants leave nitrogen behind in the soil.

When?

Sow outdoors as soon as the soil can be worked in early spring, about 4–6 weeks before your last frost. In mild-winter areas a fall sowing for a winter or early spring crop also works (estimated).

Step by step

  1. Soak seeds for a few hours before sowing to speed germination.
  2. Sow 1–1.5 in deep directly where they will grow; peas dislike transplanting.
  3. Set up netting or a trellis at sowing time, before tendrils start reaching.
  4. Keep the soil moist but not soggy until seedlings appear.
  5. Mulch lightly once plants are 4 in tall to keep roots cool.
  6. Skip heavy nitrogen feeding; peas make much of their own.
  7. Pick pods every couple of days; regular picking keeps plants producing.
  8. After harvest, cut plants at the base and leave the roots in the soil.

Common problems

White powder on leavesPowdery mildew, common in late season; improve airflow and grow resistant varieties.
Seeds not sproutingCold, waterlogged soil makes them rot; wait for drier soil or start in modules.
Plants stop floweringHeat has arrived; sow earlier next year or try a fall crop.
Chewed seedlingsBirds and mice; cover rows with netting until established.

Pets

Garden pea is not listed as toxic for cats or dogs. Ornamental sweet pea is a different, toxic plant, so do not confuse the two. If in doubt, ask your vet.
