Summer/fall bloomFrost tender
In late spring once weather is warm and settled and nights stay above 50°F (10°C), plant seeds in a sunny spot in ordinary garden soil 6 inches apart and 1 inch deep. Firm soil over seeds. Keep seedlings well weeded and watered.
Sow indoors 4 weeks before last expected frost in individual pots of seed starting mix. Cover 1 inch deep and keep warm and moist as seedlings emerge over 7 to 10 days. Provide a strong light source until seedlings are ready to plant outdoors.
Transplant very carefully once nights stay above 50°F (10°C) before plants get too crowded. Space seedlings 6 to 8 inches apart. Avoid disturbing roots as much as possible when transplanting.
Erect heavy netting, a strong trellis or a sturdy open wood or wire fence 8 to 10 feet tall at planting time to support these warm weather climbers. Guide the first young tendrils to twine onto supports. Combine with morning glories or climbing nasturtiums for a glorious summer display of flowers and pretty pods.
