Good Companions for Shelling Pea
CarrotDaucus carota subsp. sativus

Pea nitrogen fixation benefits subsequent carrot growth. Both are cool-season crops. Pea vines provide light shade for carrot seedling establishment. Same mechanism as snap pea-carrot.
Sow together in early spring. Carrots continue after pea harvest.

Garlic organosulfur compounds inhibit Rhizobium bacteria that form nitrogen-fixing nodules on pea roots. Same allium-legume antagonism.
Applies to all pea types and all alliums.
