Parthenocissus quinquefolia problems — and how to fix them
Parthenocissus quinquefolia (Parthenocissus quinquefolia) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Excessive vigour
It grows very fast and can smother shrubs, block gutters and lift loose roof tiles. Cut back hard each year and keep it clear of structures in poor repair.
Damage to weak masonry
Sucker pads grip soft or crumbling mortar. Site only on sound brickwork and prune growth away from windows, gutters and painted surfaces.
Powdery mildew
Dry roots and stagnant air encourage a white leaf coating. Mulch to conserve moisture, improve airflow, and remove affected foliage.
Unwanted seedlings
Birds spread the berries and seedlings can pop up around the garden. Pull young plants promptly before they establish a foothold.
