The leaves of the cherry laurel turn brown - what is the cause?
If the foliage of the laurel cherry turns brown and dry, there may be several reasons. We would like to help you to find out the reason and give you suitable treatment measures.
Damage due to frost or dryness during the winter months
Not all varieties of evergreen laurel cherry are completely hardy. Frost damage often does not appear until the following spring, when the leaves of the wood turn brown and dry out. As the cherry laurel evaporates a lot of moisture over the leaves on sunny winter days, drought damage is not uncommon. The frozen soil makes it impossible for the plant to compensate for the loss of fluid.
Cut frozen or dried shoots deep into healthy wood. As a precaution, you should provide the laurel cherry in very rough areas with sufficient winter protection. Pour the wood on frost-free days.
Error while cutting
Use motorized scissors when cutting the laurel hedge, as this will unnecessarily injure many leaves. The leaf margin turns brown, the leaves dried up and is subsequently dropped by the plant. Therefore, only use mechanical cutting tools when pruning the cherry laurel.
Diseases and pests
If the leaves of the cherry laurel show small reddish-brown spots, which are repelled by the plant after some time, it could be the shotgun disease. It is triggered by a fungus that can multiply explosively, especially in humid summers, and can lead to the complete dying of the plant.
In light infestation it may be sufficient to cut off the affected leaves and pick up fallen leaves from the ground. Destroy the parts of the plant in the household waste, as the mushroom survives in the compost and spreads out again in the garden when spreading the fertilizer. In case of increased infestation, the shot is treated with sprays of fungicides, which are repeated once or twice in the interval of fourteen days.
