Whenever summer comes, it seems like the arrival of the succulent死神, with all kinds of situations popping up. Here's a summary of some situations, hoping to serve as a reminder to everyone.
Succulents are prone to producing tiny white bugs called "scale insects" during summer. They survive by absorbing the sap of the plant, which can cause withering and mold infections. Due to their hard, horny shell, general insecticides are of limited effectiveness. When there are a few, they can be manually removed, and scale insects can be wiped with a cotton ball soaked in vinegar or alcohol. For larger numbers, specialized insecticides such as dinotefuran can be used.
Succulents are also prone to "powdery虱" during summer, which not only absorb water from the leaves but also excrete honeydew that can bring various molds. Affected leaves often accompany black mold disease, which can lead to the infection and death of the entire plant. Early detection and quick isolation can prevent the spread to other plants. If insecticides must be used, please wear a mask and wash your hands promptly. A slow-release granular insecticide is recommended, which can be mixed into the soil for preventive purposes.
If you find that some leaves suddenly turn black and are covered with a layer of black mold, it may be "sooty mold." Since it can cause the entire plant to turn black and rot, affected leaves should be removed immediately, and improving ventilation is key. Also, do a good job of pest control and spray some fungicides. There are also some mysterious leaf drop phenomena, such as blackening of the stem or base of the leaves, or not yet blackened but leaves falling off when slightly touched. This is also a sign of mold infection. Think about whether the ventilation has been insufficient or watering too frequently lately. This situation is very common in summer, and the planting material must be very breathable.
Succulents may also lose their original stocky shape and experience excessive stem and leaf growth during summer, a phenomenon called "etiolation," primarily caused by insufficient sunlight, overly dark lighting, and relatively frequent watering. Already etiolated plants cannot revert to their original shape. You can wait for the spring and autumn growing seasons, cut off the top, let the wound dry, and then propagate by stem cutting. Always remember to get plenty of sun (except for noon in summer), and if sunlight cannot be guaranteed, slightly reduce watering.
The above shares a comprehensive introduction to some diseases and pests that may occur in succulents during summer, hoping to bring some knowledge about green plants to plant enthusiasts.
