Why does your Hydrangea macrophylla Magical Bride have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Hydrangeas have large, thin leaves with high transpiration rates. When soil moisture is insufficient or ambient air is too dry, the plant cannot transport enough water to the leaf margins, causing tissue necrosis.
Excessive buildup of mineral salts from fertilizers or hard tap water can create osmotic stress. This pulls moisture out of the leaf cells, leading to characteristic browning at the extremities.
While 'Magical Bride' is hardy, intense afternoon sun can overheat the leaf edges faster than the roots can supply water. This thermal stress causes the marginal cells to die.
If soil remains saturated, roots begin to decay and lose their ability to function. This paradoxical 'drought' symptom occurs because damaged roots cannot uptake water even if the soil is wet.
