1. Lack of water: If there is no watering for a long time during management, the leaves will become dull and turn yellow. When there is severe water shortage in the later stage, it will start to curl. This is the state it shows in order to protect itself from water loss. If you don't replenish water in time, the leaves will easily fall off. It is important to water as soon as possible, keep it moist during the growing season, and be sure to water it thoroughly when it is dry, and also sprinkle water frequently.

Common insect pests are scale insects and red spiders, which should be checked and dealt with as soon as possible. If it is infected with scale insects, spray it with scale killer. If it is red spider mites, just remove the infested leaves directly.
