Why Do Leaves Fall Off Of Orchids?

Orchids often drop their leaves as they produce new growth, and some may lose a few leaves after blooming. Common causes of leaf drop include natural aging, advanced pest problems, root issues, inadequate lighting, and overwatering. Natural aging is a common reason for orchid leaf drop, particularly in older leaves at the base of monopodial or sympodial orchids.

Inadequate lighting is one of the leading causes of orchid leaf drop. Orchids require bright, indirect light to thrive and maintain their foliage. Phalaenopsis orchids are most common due to their tropical plant species, which enjoy plenty of moisture in the air, especially while growing new leaves, stems, or buds. Pleated foliage is almost always present.

As orchids age, they naturally shed older leaves to redirect energy towards newer growth and blooming. This process is normal and does not typically indicate a health problem. Orchids can drop leaves for various reasons, including dehydration, overwatering, pests, diseases, insufficient light, too much light, and cold. Drooping leaves are a sign of dehydration, either due to lack of watering or root death.

Orchids drop their flowers when they are no longer fertile, i.e., when they cannot generate seed. To fix this issue, it is important to feed orchids regularly with granular or liquid fertilizers. Additionally, it is essential to address any other environmental factors that may be causing leaf drop in orchids.
