Sweet peas like cool weather and can be grown anywhere as long as you have composted
soil. Peas can be grown in spring and fall. Plant seeds every 3 to 4 weeks for
continuous harvest. Plant your seeds outdoors. Spring planting should occur as
soon as soil can be worked, and fall planting done in August, September, and
October. Most varieties require stakes, trellises, or other support for the
vines to climb. Plants can grow 1 to 6 ft tall.
