Grow in poor to average, slightly acidic, well-drained soils in full sun. Plants have some tolerance for dry soils. Best performance occurs in cool summer areas. Some part afternoon shade is appreciated in hot summer areas where plants will be stressed by prolonged stretches of high temperatures. Avoid fertilization which tends to increase foliage output but decrease flower production. By reputation, nasturtiums are easy-to-grow annuals that are tolerant of a certain amount of neglect. Sow seed directly in the garden near last spring frost date, or in pots about 4-6 weeks prior to last spring frost date. Propagate by cuttings or by seed. Plants will self seed in the garden.
