• Regular watering
Blooming in bright colors, pastel shades, and white, snapdragons range in size from 6- to 8-inch dwarfs to 3-foot-tall giants. There are several flower forms; besides the familiar “snapping” type with upper and lower “jaws,” you’ll find snapdragons with double, bell-shaped, and azalea-shaped flowers.
Space dwarf plants 9 inches apart, taller kinds 15 inches apart. Snapdragons are prone to rust, so choose rust-resistant varieties. Also avoid overhead watering, which can spread rust spores. (Don’t let plants dry out, though; the disease spreads faster in hot, dry conditions.)
