What to Do When a Christmas Cactus Drops Its Leaves? Cause Analysis and Solutions

Flowers & Gardening 0 views
When a Christmas cactus drops its leaves, there are mainly four situations. The first is that the temperature is too high, so the temperature needs to be kept within 30°C. The second is too much fertilizer or too high a concentration, so the concentration needs to be lowered and the amount of fertilizer reduced, especially in summer. The third is that too much water is usually given. In that case, watering needs to be controlled. The last one is caused by pests or diseases, so the corresponding pesticide needs to be sprayed.

1. Temperature problems

(1) Specific cause: If the temperature is too high, above 30°C, and lasts for a relatively long time, then leaf drop is very likely. Especially in summer, this situation occurs quite often.

(2) Solution: In summer, appropriate cooling measures must be taken. For example, move it indoors where the temperature is more suitable, or lower the temperature by spraying water, etc. Never leave it in a high-temperature environment without attention. Specifically, it needs to be below 30°C to avoid leaf drop.

2. Fertilizer problems

(1) Specific cause: There are several possibilities. First, the amount of fertilizer is too large; second, the concentration is too high; third, raw fertilizer has been applied. Their consequences are all the same: they cause the plant to drop leaves.

(2) Solution: Corresponding to the three situations above, you need to reduce the amount, lower the concentration, and apply fully decomposed fertilizer respectively. In this way, fertilizer damage can be effectively avoided. Especially in summer, when it is dormant, you can simply not fertilize at all.

3. Water

(1) Specific cause: This mainly refers to too much water, that is, waterlogging. This aspect also mainly occurs in summer, because this is the dormant stage.

(2) Solution: Strictly control the amount of water in summer, and then strengthen the management of fertilizer and water in autumn. Also, after finding that leaf drop is relatively serious, it needs to be moved to a ventilated and shady place for care.

4. Pests and diseases

(1) Specific cause: If it suffers from disease or pest damage, and the main target of the damage is the leaves, then it may also cause the plant to drop leaves, and the situation is more serious.

(2) Solution: The earlier it is discovered, the better. After discovery, promptly remove the affected leaves and spray the corresponding pesticide.
