Rose is not honest in summer, often sick, timely spraying can save!

If the rose in the black spot, only near the lower and middle of the leaf appeared some small black spots. Then you can spray the plants with a thousand times diluted mancozeb or multi fungus liquid for treatment. If the plants get black spot, most of the leaves grow black spot, and many of the leaves turn yellow or wither. Then we need to cut off all the diseased leaves first, and then spray some 1000 times diluted multi fungus liquid around the plant and its flower soil for treatment.

Why do you get black spot?

The main reason for the black spot of rose is that the environment is not suitable for maintenance. If the place where it is raised has poor ventilation, frequent rain and high air humidity, it is easy to breed bacteria. If it is not sprayed with a low concentration of liquid medicine in time to prevent it from curing, it may suffer from black spot.

II. Treatment method when the disease is mild

If the condition of the plant is mild, only a few small black spots appear on the leaves near the middle and lower parts, and the other leaves are still healthy. It can be treated by spraying some fungicides, such as mancozeb or carbendazim. Before spraying, use 1000 times volume of clear water to dilute the solution, so as not to damage the plant with too thick medicine.

III. treatment methods for severe illness

If the disease is serious, the leaves of the whole plant appear black spots, and many leaves turn yellow or wither directly, then it is necessary to cut the leaves. Prepare a pair of sterilized scissors and cut off all the leaves with black spots, yellowing or withering. Then spray some 1000 times diluted multi fungus liquid around it and flower soil to eliminate the residual bacteria.
