You can recognize an infestation of the laurel cherry with downy mildew by the white-colored fungus on the underside of the leaf. Brown or purple discolored spots are often found on the upper side of the leaves. Downy mildew requires a lot of moisture to grow and occurs more frequently in wet weather conditions.
In the case of a mild infestation, it may be sufficient to cut off all affected parts of the plant and dispose of them in the household waste. You should refrain from composting, as downy mildew forms permanent spores that are spread in the garden when fertilizer is applied.
Before you resort to chemicals, you should tackle downy mildew with environmentally friendly agents. Spraying with garlic or onion broth has proven effective. Neem oil is considered the secret weapon against powdery mildew. When sprayed on the plant, it increases its resistance and kills the fungus. If the infestation cannot be contained, highly effective fungicides are available on the market.
