Why does your Anthurium andraeanum Dakota have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Excessive moisture in the substrate causes roots to suffocate and decay, preventing the plant from transporting water to leaves. This physiological stress triggers a sudden drop of older and even newer foliage as the plant enters survival mode.
Anthurium andraeanum is highly sensitive to cold drafts and sudden temperature fluctuations. A drop in ambient temperature below 15°C (60°F) can cause the plant to rapidly shed leaves to conserve energy.
These cultivars require high humidity (above 60%); when air becomes too dry, the plant experiences transpiration stress. Sudden leaf drop is often a response to the inability to maintain moisture levels in the leaves.
Over-fertilization leads to a buildup of mineral salts in the potting medium, which can chemically burn the delicate root system. This disruption in osmotic pressure causes the plant to drop leaves suddenly.
