American wisteria

American Wisteria plants should be watered deeply once every week or 2 during the growing season. This plant thrives in moist, well-drained soil, so allow it to dry out slightly between waterings. During periods of intense heat and dryness, you may need to water more frequently. Water thoroughly at the base of the plant, rather than spraying from above. Furthermore, in the winter months, reduce watering but do not allow the soil to dry out completely.

American wisteria prefers to grow in full sun, meaning it should receive at least 6 hours of direct sunlight per day. Ideally, it should be in an area with full sun during the entire growing season (late spring through early fall). In some cases, however, the plant may be able to tolerate partial shade, particularly if it's in a hot climate. Additionally, American wisteria can tolerate high temperatures and humidity, so it can thrive even in climate zones as hot and humid as USDA zones 4-9.

American wisteria should be pruned twice a year - once in early summer shortly after flowering and again in late winter. In early summer, remove any wispy growth and any dead or unruly branches, and prune back any overly long branches. In late winter, prune back the plant to half its current size. This will ensure healthy growth and good air circulation. When pruning, be sure to follow the natural shape of the plant, while aiming to create a balanced, open shape.
