Why does your Hydrangea macrophylla Magical Bolero 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. In dry air or intense afternoon sun, the plant loses moisture faster than the roots can replace it, causing the delicate tips to desiccate and turn brown.
Magical Bolero requires consistently moist soil. Allowing the root ball to dry out completely before watering causes physiological stress that manifests as crispy brown edges on the foliage.
Excessive use of synthetic fertilizers can lead to a buildup of mineral salts in the growing medium. This increases osmotic pressure, making it harder for the hydrangea roots to absorb water, resulting in tip burn.
While they love moisture, stagnant water deprives roots of oxygen. If the roots begin to rot due to poor drainage, they lose the ability to transport water to the leaf margins, causing them to turn brown.
