Disease control

Leaf drop symptoms

First, it is because of management problems. Improper management will cause the plant roots to rot and the leaves to become wrinkled and shrunken. This situation is caused by high air humidity and poor ventilation. At this time, you need to spray some fungicide and control the dosage of the fungicide. If leaves fall off or turn yellow in a short period of time, this may be caused by temperature imbalance and insufficient light, so provide sufficient light on time.

Developmental failure

When planting, if alkaline soil is used, the plants will be short and their growth will stop. Sometimes it is also caused by the alkaline water used for irrigation. In this case, you can loosen the soil regularly, remove the top layer of soil, add some new soil, and then add a small amount of diluent to improve the soil properties.

Viral diseases

Viruses are substances that are invisible to our naked eyes. They can parasitize in the living cells and tissues of plants, and then transfer to various parts of the plant along with organic matter. When encountering this situation, we need to remove the diseased plants in time and choose plants in good health for cultivation.

Pest Control

Grubs are generally called scarabs and have white flesh. It can feed on the roots of the plant and gradually damage the plant. The way to prevent and control this pest is to remove the insects you see when repotting, and then use an insecticide to sterilize the roots.

Mole crickets are insects that spread through water. They can cause a gap between the roots of plants and the soil, making it difficult for the plants to absorb water. When handling, remove the visible ones, and then use wheat bran to lure and kill them.
