Hedges not only ward off the curious glances of neighbours, they also take on important ecological functions, by providing sanctuary for animal and plant species that would otherwise not exist in many gardens.
Hedges - a versatile part of our gardens. They demarcate land and at the same time form an effective visual and noise protection. But what do you do if your favourite hedge falls ill?
Powdery mildew on the underside of the leaves
The evergreen cherry laurel is one of the most popular hedge plants: It grows fast, is robust, can be easily cut back and tolerates wintry frost as well as summer drought. For some years, however, the popular cherry laurel is becoming more susceptible to powdery mildew, which settles on the underside of the leaf and not, as usual, on the leaf top. This often leads to wrong diagnoses and thus to wrong treatment with avoidable consequences. In any case, rapid action is required in cases of infestation with these typical hedge diseases - from large-scale cutting back of the affected areas to the use of suitable fungicides.
Act quickly against damage by insects.
In addition to fungal infections, hedges often suffer from damage by insects. One of the most common pests is the small winter moth, which has a special preference for beech and hornbeam hedges and likes to fill itself up on the tender leaves. The caterpillars of the small butterfly can often be clearly seen. As soon as the first night frosts occur in late autumn, the insects hatch from their hiding places and the females lay their eggs on the young shoots. In the spring, the larvae hatch from the eggs - the first feeding damage is then just a matter of time. In order to avoid permanent or even irreparable damage to hedges, the targeted use of pesticides is recommended in the event of a visible infestation of insect pests.
Whether it's insect damage or fungal infection - quick action is advisable. From large-scale pruning to the use of suitable pesticides, your hedge will thank you.
Checklists & tips
If you notice any obvious damage to the youngest leaves of your cherry tree hedge, look no further than powdery mildew
A whitish deposit on the underside of the leaves and curling of the leaves are clear signs of powdery mildew.
The picture is quite different with downy mildew: Visible discolouration from yellow to brown can be observed on the upper side of the leaf.
