Description
A large, long-lived climber so choosing the right site is important. Can be grown informally through a large tree or more formally against a house wall.
Wisterias will grow in most soils that are moist but well-drained.
Pruning: Wisterias can be left to ramble unchecked where space allows but will usually flower more freely and regularly if pruned twice a year.Cut back the whippy green shoots of the current years growth to five or six leaves after flowering in July or August.Then, cut back the same growths to two or three buds in January or February (when the plant is dormant and leafless) to tidy it up before the growing season starts and ensure the flowers will not be obscured by leaves.
