did you know?

The sweet pea patch is one of Martha's favorite places in the garden. Sweet peas were also beloved by gardeners in Edwardian England, who grew the plants for their color and fragrance. More than 260 varieties had been cultivated by the end of the 19th century.

general maintenance:

Help plants climb their support by loosely securing with ties if necessary. Mulch to keep soil cool, maintain moisture, and suppress weeds. Deadhead spent blooms to promote flowering.

pests/diseases:

Snails, slugs, aphids, and powdery mildew may occur.

controls:

Handpick slugs and snails, or spread diatomaceous earth around plants. Regularly hose off aphids with a directed stream of water, or apply insecticidal soap, following label directions. To discourage powdery mildew, space plants to improve air circulation and avoid wetting leaves when watering. Pick off diseased leaves where practical, and remove and destroy severely infected plants.

how to sow/plant:

In frost-free areas, direct sow in late summer to fall for early spring blooms; in areas with colder winters, sow in early spring. To encourage germination, soak seeds overnight or nick seed coats with a sharp knife. Choose a sunny, well-drained site, and amend soil with compost or well-rotted manure before planting. Plant 2?3 inches apart and 2 inches deep, pressing the soil down lightly. Erect a webbing-covered trellis or other support at planting time to avoid disturbing roots later. Thin young plants to 9?12 inches apart.

water and fertilize:

Maintain soil moisture all season. Apply a balanced, water-soluble fertilizer biweekly, following label directions.

garden hint:

To encourage sweet peas to continue blooming, clip the flowers every few days.
