Bathe plants: Bathing plants (that is, washing them with hoses or shower heads) can drive away many pests. Bathing plants in late autumn can also remove dust from leaves. Be careful not to wash too hard, so as not to hurt branches and leaves. At the same time, care should be taken not to scratch plants when washing.
Change pots only when it is time to change pots: unless potted plants are full of roots and have nowhere to stretch, there is no need to change pots. It is best to change pots in early spring. At the same time, pay attention to the situation before changing pots, and then change pots when the soil is wet and dry.
Keep humidity: overheated and dry air is not good for potted plants, and it is easy to make tetranychus urticae more active.
To keep the humidity of potted plants, we might as well take these measures: (1) use a humidifier; (2) put the plants in the same place; (3) Put the plants on a tray filled with water and pebbles (water should not flood pebbles).
