Underwatering / Drought Stress

This cultivar has large, thin leaves with high surface area that lose moisture rapidly. If the root ball dries out completely, the plant sacrifices the leaf tips to conserve water for the main stem.

Very Common

Salt Accumulation (Fertilizer Burn)

Excessive buildup of mineral salts from fertilizers can draw moisture out of the leaf cells via osmosis. This typically manifests as distinct, scorched-looking brown tips on the hydrangea leaves.

Common

Root Damage or Container Boundness

If the roots are circling the pot or have suffered damage from compaction, they cannot supply enough water to the extremities of the large 'Magical Colordream' leaves. This results in tip necrosis.

Common

How to confirm: Gently lift the plant from its container to inspect if the roots are tightly coiled or if there is any dark, foul-smelling rot.
