Why does your Hydrangea macrophylla Magical Flamenco 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 the air is too dry, the plant cannot move water to the leaf margins fast enough, causing the tips to desiccate and turn brown.
Excessive buildup of mineral salts from fertilizers or hard tap water can cause osmotic stress. This prevents the 'Magical Flamenco' hydrangea from absorbing water effectively, leading to necrotic leaf edges.
Strong or dry air currents can rapidly evaporate moisture from the leaf margins of large-leafed hydrangeas faster than the roots can replenish it, resulting in crisp, brown edges.
While brown tips often suggest drought, overwatering can lead to root decay. As the root system fails due to lack of oxygen, it loses the ability to supply water to the leaf extremities, causing tip dieback.
