How to Handle Yellowing Leaves and Root Rot in Clivia

One cause of yellowing leaves in clivia is that no new roots grow from the leaf axils while the leaves turn yellow. This is mostly due to raw, poorly aerated soil, excessive fertilizer, or poor control of watering dryness and moisture that causes root rot, all of which can make clivia leaves turn yellow. If watering does not soak through, the root tips lack moisture, which causes the leaf tips to turn yellow and dry out. When this happens, you must water thoroughly. In summer, every 7-10 days you can set the flower pot bottom in a small basin of water, which ensures thorough watering. Another situation is the appearance of yellow spots of varying sizes on both sides of the leaves, called brown spot disease. This is mainly caused by relatively raw soil and excessive fertilizer application. Generally, the potting soil should be leaf mold soil, which has fairly good aeration. Especially when fertilizing in summer, you should apply thin fertilizer frequently and spray plant cell immune factors to enhance the plant's stress resistance, which can cause viral DNA to break down and die. It strengthens immune function, induces interferon and active cytokines, inhibits replication of residual viruses, and promotes positive-energy ecological growth of the plant. Using the host plant's disease resistance mechanism and the principle of pathogenic virulence variation, it controls the proliferation of plant physiological diseases and infectious diseases. In this way, the occurrence of brown spot disease can be prevented. Yet another situation: because summer has abundant sunlight and higher temperatures, if clivia is placed in direct sunlight, sunscald can also occur, with mild cases showing yellowing leaves and severe cases showing wilting. In summer, shade should be provided, the plant should be placed in a ventilated spot, and new high-fat film should be sprayed for sun protection and drought resistance. (Dadi)
