Why does your Tiarella cordifolia have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyTiarella cordifolia thrives in moist, humid woodland environments. When the surrounding air is too dry, transpiration exceeds moisture uptake, causing the delicate leaf margins and tips to desiccate.
Excessive mineral salts from fertilizers can accumulate in the leaf tissue. In foamflowers, this osmotic stress draws water out of the cells, leading to characteristic scorched-looking brown tips.
While Tiareella prefers moist soil, letting the root ball dry out completely before watering causes hydraulic failure at the furthest extremities of the leaf, resulting in tip necrosis.
Some cultivars of Tiarella are sensitive to high concentrations of chlorine or fluoride found in municipal tap water, which can manifest as tip burn.
