How to Grow and Care
Most species have spectacular, colorful flowers and are often grown as ornamentals, and a number of cultivars have been developed. In the garden, Ipomoeas need moderately fertile, well-drained soil in full sun. Provide shelter from the wind. Prune climbing species in spring. Under glass, provide full light with protection from the hottest sun. Water freely and fertilize monthly during the growing season, but water sparingly in winter. Climbers and trailing species need support. Chip seeds with a knife, scrape with sandpaper or soak in water for 24 hours before sowing at 64° F (18° C) in spring.
Root softwood cuttings of perennials or shrubs in spring or summer, or take semi-ripe cuttings in summer. White blister, rust, fungal leaf spots, stem rot, thread blight, charcoal rot, and wilt can occur. See more at How to Grow and Care for Ipomoea.
