Pests and diseases

Listed here is every problem for which the sources name this plant as a host. The problems are not listed in order of how common they are.

Honey fungus

disease
Signs
The plant dies suddenly, often in mid season and without any decline beforehand. Peel the bark at ground level and under it there is a white or cream sheet of fungal tissue, thin as the skin of a mushroom. In the soil there are black or brown strands like bootlaces. In late summer and autumn tufts of honey brown mushrooms with a whitish ring on the stalk appear by the stumps or over dead roots.
Prevention
The fungus spreads through the soil with its strands, from a few centimetres to a good hand's width below the surface, and infects the roots of a living plant when it touches them. So do not leave stumps and dead roots in the ground. No plant is completely resistant, but the source names privet, lilac, viburnum, weigela, forsythia, butterfly bush, rhododendron, thuja and walnut as particularly susceptible.
What to do
There are no products. The only thing that works is digging out and removing every infected root and stump, which takes away the food without which the strands in the soil do not grow. A vertical barrier of rubber or thick plastic sheet, buried about half a metre deep and standing a few centimetres above ground, stops the spread into an unaffected part of the garden.

Vine weevil

pest
Signs
The half round notches along the leaf edges in summer are the work of the adult beetles and do the plant little harm. The larvae are the danger: white grubs with a brown head eat the roots, the plant suddenly drops its leaves and dies, most often between autumn and spring.
Prevention
Most at risk are plants in pots and troughs. In a bed the damage is rarer. At repotting check the roots and the compost and pick the larvae out. You find the adult beetles in the evening with a light, when they crawl over the plants.
What to do
Pick the adults off in the evening, set sticky traps indoors and change the compost, removing the larvae as you go. There is no insecticide. As biological protection, water beneficial nematodes into the compost at the end of summer, while the larvae are still small.
