1. The simplest and most direct method is to spray water on the plants and the surrounding ground frequently. If possible, spray it 2-3 times a day, and it is best to use an atomized sprayer. The misty water can surround the plants like a mist, forming a small environment with high humidity.


2. Put the flowerpot in a shallow tray with water, cover the tray with gravel, and pad the flowerpot so that the bottom of the flowerpot cannot touch the water in the tray. As the water evaporates, the humidity around the flowerpot is increased. Or place a shallow water tray near the flowerpot. The larger the water surface, the better the effect. 

3. The deep basin evaporation method is to place the plants in a large, high and deep container with a small amount of water to obtain a stable high humidity environment. 

4. Put the flower pot in a larger-diameter set of pots, and put water-absorbent materials, such as shredded paper, rags, peat soil or sawdust, in the gap between the two pots. These materials will gradually release water vapor and surround the plants.

5. Cover plastic film. You can cover the flowerpot with a transparent plastic bag or a film in the cover while putting a pot of warm water 20°C higher than the room temperature to increase the air humidity in the small environment. In households with heating equipment, a damp cloth can also be laid on the radiator to heat it to produce water vapor, which can also create a locally humid environment.

However, it should be noted that no matter what the above methods are used in the winter, the plants must not be placed near the heater, otherwise the pot soil will be dried quickly and the plants will die due to loss of water. In addition, if you can frequently scrub the leaf surface, you can also remove the dust clogging the stomata and make the leaf contact more water vapor.
