Before Planting

Choose a cool, full-sun site with rich, well-drained soil and afternoon shade where summers are hot. Incorporate compost and install a trellis before sowing. Soak seed briefly or nick hard seed coats if desired, but discard damaged seed and avoid prolonged soaking.

Planting

Direct sow sweet peas in early spring as soon as soil can be worked, or sow in fall where winters are mild. In very cold areas, start them indoors 4–6 weeks early in deep cells that protect the roots. Keep the medium evenly moist and cool. Transplant carefully, and direct climbing shoots onto their support as growth begins.

Watering

Once established, sweet pea prefers deep, infrequent watering. Let the surface dry between irrigations, supply extra moisture during extended heat, and avoid keeping the crown continuously wet.

Fertilizer

Fertilize sweet pea according to soil-test results, usually without added nitrogen. Excess nitrogen reduces nodulation and favors excessive foliage, while phosphorus or potassium may be needed on deficient soils.

Harvesting

Sweet Pea flowers are ready when stems are firm and blooms show mature color without fading. Cut during cool, dry conditions; for seed, leave selected heads until brown and dry.

Tips

Train sweet peas onto netting while stems are young and pick flowers frequently to extend bloom. Seeds and pods are toxic if eaten; clearly distinguish ornamental sweet peas from edible garden peas.

Pests & Diseases

Ascochyta blight, powdery mildew, downy mildew, Fusarium wilt, and viruses affect sweet peas. Use pathogen-free seed, rotate legumes, and keep vines dry. Remove plants with stem lesions, persistent wilt, or mosaic. Never save seed from spotted pods or allow diseased residue to remain.

Sweet Pea may attract sap-feeding aphids and leafhoppers, chewing beetles, weevils, and cutworms. Scout new growth and pods, use physical removal, and preserve lady beetles and other beneficial insects.
