Red spots appear on kalanchoe in summer, affecting leaf growth - treat promptly for a safe summer
Many people like kalanchoe; its flowers are gorgeous and the flowering period is long. It is a succulent, so it is not very difficult to grow. However, if care is not proper, various small problems can still arise. Just like what a flower enthusiast said about the problem of red spots appearing on kalanchoe leaves. Here, Xiaonong will talk with everyone about kalanchoe care issues.
Red spots appear on kalanchoe
Because the flower enthusiast did not provide a photo of their kalanchoe, it is impossible to accurately determine what kind of disease their kalanchoe has. However, if kalanchoe develops leaf spot disease, spots will also appear, though the spots are brown in color. Leaf spot disease is a disease very likely to occur during kalanchoe cultivation. Kalanchoe with leaf spot disease is also contagious, and if not treated promptly, it can very easily cause large-scale damage to the kalanchoe plant.
For kalanchoe with leaf spot disease, do not be soft-hearted; promptly cut off the leaves that have already developed the disease to avoid contagion. Then spray the kalanchoe leaves with a 1000-fold dilution of carbendazim aqueous solution, and note that both the front and back of the leaves must be sprayed. Do this twice a week, and it will improve in about two weeks. If the kalanchoe leaf spot disease is relatively severe, flower enthusiasts may consider repotting the kalanchoe; before repotting, soak the kalanchoe in a 1000-fold dilution of carbendazim aqueous solution for about two hours. Then replace the soil and the pot to reduce fungal infection.
In addition, in summer, with high temperatures and relatively strong sunlight, kalanchoe is prone to sunburn, and at this time red spots or red leaf edges may also appear. At this time, flower enthusiasts should promptly move the kalanchoe to a shady place, and pay attention to cooling and shading.
What was said above are the treatment methods for kalanchoe leaf spot disease and sunburn. In addition, kalanchoe enters dormancy in summer, and at this time fertilization should be stopped, otherwise nutrients may not be absorbed and root rot may occur. Summer is relatively hot and stuffy, so flower enthusiasts should pay attention to maintaining the kalanchoe's growing environment with ventilation and air permeability, avoiding stuffy and hot soil in the pot and root rot. Watering should depend on the potting soil and weather conditions, generally watering thoroughly after the soil has dried completely.
