What if there are white spots on plants?

Timely medication can play a preventive and therapeutic role.

White spots on flowers and leaves are generally caused by the destruction of plant growth environment and the infection of pests and diseases, or by the lack of nutrients in pots.

If the place where potted plants are placed is poorly ventilated, the humidity is too high and the temperature is relatively high, plants will breed pests and diseases in a hot and humid environment. Therefore, it is necessary to improve the conservation environment in time, adjust the means of conservation, and then use drugs to kill pests and diseases. For scale insects and cotton scale insects, it is usually used to melt or kill scale insects, diluted with water and sprayed with pesticides.

The scale of grass or cotton belongs to wax shell, and pesticides are added to enhance the efficacy and adhesion. Generally, it is sprayed once a week and continuously for 2-3 times to play a preventive role.

Precautions for plant protection:

1, light

Insufficient light will cause the leaves of plants to fall off or shrink, especially in winter when sunshine is scarce, and each plant has different requirements for light. Some plants like sunshine, while others like shade. Proper illumination should be given according to the living habits of different plants, but for most plants, it is not suitable for direct sunlight.

Step 2 avoid drought

If the soil in the pot is dry, the buds fall off and the leaves of the plants are exposed, it is necessary to water it. The simplest and most common way to check whether the soil in the basin is dry is to put your finger on the soil, but this method is not completely reliable, because it is likely that the soil above is dry and the soil below is wet. Pick up the flowerpot. If it feels light, it means that the soil is almost dry, which means that the plants need watering.
