By June, your statement wisteria climber is done flowering and focusing on foliage growth. While it's easy to assume it can be left alone for the rest of the year, neglecting wisteria summer care can set up next year's display for disaster.
The truth is wisteria care is year-round, even if its blooms only stick around for a few weeks at a time in May. After blooming, deadheading, light pruning, and tying in new growth is essential to keep this climber in top condition and support the vigorous growth it's putting out. Plus, a little TLC now will help your plant conserve energy for next spring's blooms.
