Parthenocissus tricuspidata problems — and how to fix them
Parthenocissus tricuspidata (Parthenocissus tricuspidata) 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.
Damage to walls and gutters
Adhesive pads can pull at soft mortar and the dense cover invades gutters and under eaves. Keep growth cut back from roof lines, windows and brickwork in poor repair.
Powdery mildew
A white coating appears on leaves in dry, crowded conditions. Improve air movement, water at the base in dry spells, and remove badly affected growth.
Over-vigour
It grows fast and can swamp neighbouring plants and structures. Prune in summer and winter to keep it within its allotted space.
Leaf scorch
Hot, exposed positions with dry roots can scorch leaf margins. Mulch to retain moisture and water young plants through droughts.
