The main threat to the health of dracaena comes from the scale insects and thrips. When a tree is infected with a spider mite, a premature shedding of leaves is observed.
Often, a brown spot forms on the leaf blades, after which the leaf dries completely. The plant loses its vitality and begins to ache. The reasons for these problems are the presence of dry air in the room and lack of watering.
With excessively bright lighting, foliage runs the risk of getting burns, which appear as dark spots. To avoid overheating, it is recommended to shade the flowerpots from the scorching sunlight.
