1, temperature control, potted apple trees are suitable for growing in a warm environment. In winter, potted apple trees can be placed indoors, and the temperature can be controlled above zero, or in a heated room, the temperature can be controlled below 20 degrees.

2. Reduce watering. Apple trees need a lot of water in the process of growth, but in winter maintenance, it is necessary to reduce the water supply to avoid yellowing of leaves due to excessive watering. At the same time, when watering, you can spray a small amount of water on the leaves to keep the environment moist.

3, proper pruning, apple trees grow slowly in winter, you can properly prune, cut off the densely growing or poorly growing branches on the plant, and cut off the longer growing branches at the same time, save nutrients for the plant, control the growth direction of the plant, and make the potted plant more beautiful.

4, disease prevention, indoor air is not circulated in winter, and the growth environment of apple trees is relatively humid, which provides a good environment for the propagation of pathogenic bacteria. Therefore, infected plants must be cut off immediately, the planting soil should be changed and replanted, and kept in a warm and ventilated environment.
