Why does your Rhododendron kaempferi have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Excessive moisture or poor drainage in acidic soil leads to fungal pathogens attacking the root system of the Azalea. This prevents water uptake, causing the plant to shed leaves rapidly as a stress response.
Rhododendron kaempferi is sensitive to sudden shifts in temperature or radical changes in humidity. Moving the plant to a location with direct afternoon sun or extreme frost can trigger an immediate leaf drop.
Azaleas have shallow root systems that are highly susceptible to drying out. If the soil substrate becomes completely desiccated, the plant will drop leaves to reduce transpiration and conserve moisture.
Accumulation of mineral salts from tap water or excessive synthetic fertilizers can burn the delicate roots. This physiological stress often manifests as sudden wilting and leaf abscission.
