Why does your Rhododendron atlanticum have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Atlantic Azaleas are sensitive to high levels of salts from tap water or synthetic fertilizers. These salts accumulate in the leaf margins, drawing moisture out of the tissue and causing tip necrosis.
As an acid-loving shrub, Rhododendron atlanticum requires consistent moisture. When the substrate dries out too deeply, the plant cannot transport water to the furthest extremities of the leaves, leading to brown tips.
Atlantic Azaleas prefer humid environments; extremely dry indoor or garden air can cause rapid transpiration that exceeds the root's ability to resupply water, resulting in desiccation at the leaf edges.
Applying high-nitrogen fertilizers too close to the root zone or in excessive concentrations can cause osmotic stress. This draws water away from the leaf tips, causing them to turn brown and crisp.
