Black spots on roses and leaves: causes and treatment
Black spots appeared on the flowers. This usually happens for several reasons. The main thing is to understand why this happened, to respond quickly and reanimate the rose. The most common cause of black spots on roses and leaves is a fungal infection.
This can happen due to the wrong choice of a place for planting seedlings. For example, roses were planted too close to each other, which led to a violation of air exchange. Also, the rose garden could be placed on a damp, poorly ventilated area. Another cause of black spots on roses can be the wrong dosage and untimely application of dressings.
As soon as you find the cause, immediately proceed to treatment. Treat the rosary at least once every two weeks with such preparations as: Profit, Skor, Oksikhom or other fungicides.
