Wisteria pruning is done twice a year, first in July or August and then in January or February. The tendrils of this fast-growing climber are cut back to just a few inches during the summer.
In the fall and winter, Prunings are trimmed back again, this time to about a quarter of their original length. In the spring, they are re-trimmed to the same length as they were at the beginning of the growing season.

How far back can I cut my wisteria?
The new shoots and flowers will be beared by these buds. Pruning overgrown wisteria can be done as well. In this case, wisteria trimming can be accomplished by lopping and cutting as much as you want, down to about 1/3 of the plant’s height.
Wisterias can also be pruned to make them more attractive to birds and other wildlife. This is done by cutting off the top branches and leaving the lower branches bare. The leaves can then be trimmed back to the desired length.
Can you cut back wisteria in the summer?
Cut back the whippy green shoots of the current year’s growth to five or six leaves after flowering in july or august. This controls the wisteria’s size so that it doesn’t get into windows and guttering, and encourages it to grow flower buds in the fall.
Dry out the plant by covering it with a thin layer of mulch, or by placing it in a cool, dark place for a couple of weeks. It’s best to do this in late summer or early fall, when the weather is cooler and the soil is more moist.
If you don’t have a place to dry out your plant, you can use a garden hose to spray it down with water until it dries out completely.
Does wisteria bloom on old wood?
Wisteria produces its flowers buds during the previous growing season (“blooms on old wood”). The buds of the plants would be ready for harvest in late spring or early summer if the plants were pecked from late fall to early spring. If the plant is grown in a greenhouse, the blooming season can be extended to late summer or fall, depending on the type of greenhouse and the amount of light it receives.
Should you deadhead wisteria?
The fruits of wilted flowers do not mature as quickly as those of other plants. Keep the soil moist, but not soggy, during the growing season, especially in the spring and summer when the flowers are in bloom. This helps to keep the plants from drying out and to prevent them from becoming stunted and dying.
Can you keep wisteria small?
A large amount of growing space is required by wisterias. However, their lacy foliage and exceptional beauty in bloom can still be enjoyed in small gardens, if they are trained as a standard, with their flowers hanging down to the ground.
How do I bring wisteria back to life?
You don’t need to be afraid when you see leaf scorch on your plant. The plant will revive itself in a couple of months. If it’s summer, just water the plant and it will come back to full health.
