Why does your Rhododendron bureavii have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Rhododendrons are sensitive to high concentrations of salts and minerals in soil. Excess fertilizer buildup or hard water irrigation causes osmotic stress, leading to necrosis at the leaf margins.
Bureau's Rhododendron requires consistently moist but well-draining soil. When the substrate dries out completely, the plant cannot transport water to the furthest extremities, causing leaf tip burn.
While brown tips often suggest dryness, poorly draining soil can lead to root rot. As roots decay, they lose the ability to supply water to the leaves, mimicking drought symptoms through tip necrosis.
In very dry indoor or greenhouse environments, the transpiration rate can exceed water uptake. This causes the edges of the leaves to desiccate and turn brown.
