How to prevent and treat yellowing leaves in clivia? A detailed guide to edible mushroom cultivation techniques

Yellowing clivia leaves generally occur in several situations. If the bottom leaves produce new roots from the leaf axils and the leaves turn yellow, this is normal metabolism. In one situation, no new roots grow from the leaf axils while the leaves turn yellow; this is mostly caused by raw soil, poor air permeability, excessive fertilizer, or poor control of watering dry-wet levels leading to root rot, all of which can cause clivia leaves to turn yellow. If watering does not soak through, the root tips lack moisture, which causes the leaf tips to turn yellow and dry. 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; this is called the soaking method.

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 fertilization. Generally, the potting soil should use leaf mold soil, which has relatively good air permeability. Especially when fertilizing in summer, you should apply thin fertilizer frequently, and never drip fertilizer water onto the leaves; this can prevent the occurrence of brown spot disease.

In yet another situation, because summer has ample sunlight and relatively high temperatures, if clivia is placed in direct sunlight, sunscald can occur; in mild cases the leaves turn yellow, and in severe cases they wilt. In summer, shading should be adopted and the plant placed in a ventilated spot, with 50% shade being best. For a south-facing window at home, one layer of gauze can be used for shading.
