Rolled leaves are an indication of aphid infestation
Why do Leaves of the Liguster roll in?
If the privet gets rolled-up leaves in the spring, the garden owner must assume that a pest has attacked the shrub or the hedge. Why are the leaves rolling and how dangerous is that for the privet?
Privet - Leaves curl up
The problem that the leaves of the leaflet curl up, dry up and finally fall off occurs primarily in spring.
The sight is not very pretty, but you do not have to worry about the privet suffering from a serious illness. The cause is a pest infestation by the privet louse.
Healthy privet hedges get along well with an infestation alone. So you do not necessarily have to do anything, as long as the privet louse does not appear in epidemics.
Fight privet louse
If the pest infestation is very strong, you can try to use special pesticides. It is even better if you count on natural enemies of the louse, ladybugs and lacewings.
But most of the spook is over after a few weeks and the privet expels new, healthy leaves.
Cut off affected shoots
If the sight of rolled, dried leaves disturbs you, cut off all affected shoots generously. Privet can easily tolerate a strong pruning.
Do not throw the cut remnants on the compost, but dispose of them in the household waste. This also applies to the fallen leaves that you should rake up and put in the garbage bin.
Prevention is difficult
The rolling up of the leaves of the Ligusters by infestation of the privet louse can hardly be prevented. Make sure the shrub is healthy. Do not plant the privet in the hedge too tightly and clear the shrubs regularly:
For very nutrient-poor soils, you should give additional fertilizer from compost and horn shavings. This strengthens the privet, so he overcomes the infestation without any problems.
Tips
If the privet loses its leaves in autumn and winter, this is a natural process. The shrub is not evergreen. In the spring, the foliage repels.
