What is the disease of rose leaf curling? What should I do if the leaves curl?

1. What is the disease

Its curling leaves may be infected with leaf spot disease, which will cause the leaves to necrotize, have yellow spots, and slowly curl. This phenomenon occurs on both new and old leaves. In addition, it may also be caused by insect pests. Some common pests include red spiders and scale insects. If there are pests on the leaves, they will suck the juice inside and gradually cause curling.

2. Causes of the disease

The above-mentioned diseases and pests are mostly caused by improper management. During the management period, a humid and stuffy environment is provided, which is easy for pathogens and pests to breed, and the plants will be infected. In severe cases, it may even cause death, so treatment must be given as soon as possible to prevent further deterioration.

3. What to do

Once pests and diseases are discovered, measures must be taken to treat them. All diseased leaves should be cut off and destroyed completely to prevent further infection. You also need to change your environment, move to a well-ventilated place, and increase ventilation. Usually, let it get more sun, control the amount of watering, and do not overdo it. The soil must not accumulate water. It can be kept dry and wet, and spray water frequently to increase the humidity. In addition, pesticides should be sprayed for treatment. Just spray the disease with general disinfectant. Imidacloprid can be used to treat insect pests, which is more effective.
