Q.Virginia Creeper
We have a really established Virginia Creeper, at least 100 years old. It’s pictured on all Lincolnshire. This year it looks really poor. The new foliage is dying, with large bold patches. Please help.
Inspect the vine for signs of insects; scale, aphids, mites, leaf hoppers or Japanese beetle can all attack the plant.
Neem Oil can be used to treat generally any sucking pests.
Regular pruning is helpful to keep this fast growing vine healthy.

Also inspect for black or brown areas of leaves, or sunken areas.
Fungus could include Leaf spot, Anthracnose and Canker.
Keep the ground clear of any dead leaves or plant material and dispose of.
Make sure when watering you do not splash the leaves of the plant.
Pruning can help air circulation.
Neem Oil can also help with fungus issues or a fungicide treatment.
