About Peas

Peas are cool-season crops that prefer the shoulder seasons — they dislike both hard frost and summer heat.

Sow directly as soon as soil can be worked in spring — peas tolerate frost. Provide a trellis. Harvest frequently to encourage production. Sow again in late summer for a fall crop.
