Reasons for the complete defoliation of "Le碰碰香" leaves

1. Improper care

One of the reasons for the complete defoliation of "Le碰碰香" leaves is improper care. Here are some common care issues:

(1) Overwatering or underwatering: Overwatering can lead to root rot, which in turn affects leaf growth; underwatering can cause the soil to dry out, resulting in the leaves losing moisture and drying up.

(2) Insufficient lighting: "Le碰碰香" plants enjoy ample sunlight. If they are kept in a dark environment for an extended period, the leaves will gradually turn yellow and dry up.

(3) Improper fertilization: Both excessive and insufficient fertilization can affect the growth of "Le碰碰香" plants, leading to leaf drop.

2. Pest and diseases

The complete defoliation of "Le碰碰香" leaves may also be due to the invasion of pests and diseases. Here are some common pests and diseases:

(1) Aphids: Aphids will absorb the sap of the plant, causing the leaves to turn yellow and dry up.

(2) Spider mites: Spider mites will absorb sap from the back of the leaves, causing the leaves to turn yellow and dry up.

(3) Root rot: Root rot can lead to root decay, which in turn affects leaf growth.

Methods to prevent the complete defoliation of "Le碰碰香" leaves

1. Improve the care environment

(1) Proper watering: Water according to the dryness or moisture of the soil, avoiding too much or too little water.

(2) Increase lighting: Place the "Le碰碰香" plant in a sunny location, ensuring at least 4 hours of direct sunlight per day.

(3) Proper fertilization: Fertilize according to the instructions on the fertilizer, avoiding too much or too little.

2. Treat pests and diseases
