Please do not be alarmed: White spots on the leaves of plants are not always a danger. There is a mushroom behind it - but often you don't have to fight it.
Cologne (dpa / tmn) - Especially when it is dry and warm longer, white spots form on the leaves of many plants in the garden. Powdery mildew is a fungus that occurs, for example, on the spindle shrub, roses, cherry laurel, hydrangea, rock pear and trumpet tree.
But the infestation is not always strong enough to cause serious damage to the plants. Rather, the crop protection service of the North Rhine-Westphalia Chamber of Agriculture believes that control is "often not necessary".
Hobby gardeners recognize a very strong infestation by the fact that the leaves also turn brown and die as a result. Otherwise there are only single white flour-like spots on the green, which increase in number and size until the leaves are completely covered with them.
But of course it doesn't look nice. If the fungal infestation bothers you, you should remove the affected leaves and dispose of them in the residual waste.
