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. features:
