Wisteria may be famous for its spectacular spring flowers, but July is the month when a little care can make all the difference to next year's display. As summer temperatures climb – with parts of the US experiencing intense heat dome conditions and prolonged heatwaves – gardeners need to pay closer attention to watering, pruning, and protecting plants from heat stress.
While established wisteria is a resilient climber, extreme heat can put even mature plants under pressure. The right approach to wisteria care in July will help keep growth healthy, prevent the plant from becoming unruly, and encourage a stronger flush of flowers next spring.
