When to prune Wisteria

Wisteria is pruned twice a year, in July or August, then again in January or February.


How to prune Wisteria

Wisteria needs pruning twice a year to keep it floriferous and to prevent it from growing out of its allotted space.


Summer Pruning 


(JULY or AUGUST)
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 size of the wisteria, preventing it getting into guttering and windows, and encourages it to form flower buds rather than green growth.



Winter Pruning 


(JANUARY or FEBRUARY)

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.
