Goldliguster is characterized by high robustness. So we can enjoy its golden-green leaves, the fragrant flowers and the small berries in autumn for years without a hitch. But an existence without any diseases would be too good to be true.
The Goldliguster very rarely gets sick
brown leaves
Brown leaves are often interpreted as a symptom of disease. But a closer look is necessary here. If the new shoots are brownish in spring, a bright location is very likely responsible. The leaves have to get used to the sun first.
If brown leaves also appear at other times, care is usually not correct. Extensive fertilization in particular can cause the leaves to turn brown. Another possible cause is a long extremely dry or wet period.
powdery mildew
Goldliguster can occasionally suffer from powdery mildew in summer. A mealy-white matter becomes visible on the leaves. Although the disease is so visible, privet sprays are not usually necessary.
leaf spot disease
Numerous brown to black spots on the leaves indicate an infestation with the leaf spot fungus. Humid summers favor the onset and spread of the disease. Leaf loss can occur. Act promptly after discovering the disease to stop it from progressing and affecting more parts of the Goldprivet.
- cut off all affected parts
- Clean and disinfect scissors beforehand
- Do not compost what is cut off, dispose of it as residual waste
- In the case of severe or stubborn infestation, spray a preparation containing copper
tips
Be careful not to fertilize the gold privet too much with nitrogen. In this way, the plant tissue does not become spongy, which would promote the spread of the fungus.
wilt fungus
The wilt fungus, technically correct Verticillium, rages in the soil in the root area of the golden liguster. His presence there goes unnoticed at first. However, the damaged roots can soon no longer adequately supply the above-ground parts of the plant.
The leaves curl up, show color changes, dry up and fall off. Entire shoots can also die off. If the disease is not contained, further growth is very slow and the gold privet shows sparse foliage.
The fungus cannot be controlled chemically. Soil replacement in the root area can make sense. Injuries to the flat roots should also be avoided so that the fungus does not get any further entry points.
