Set plants 3 feet apart in full sun or partial shade. Itea is widely adaptable to soil type, tolerating wet or dry conditions. Full sun and dry soil will produce more compact growth and more brilliant fall color.
Prune in early spring to remove weak shoots, old woody growth, and winter killed branches. In the north it should be pruned to ground level in winter, treating it much like a Buddleia. New growth will produce the next spring. Provide a mulch for winter protection.
