Why does your Hibiscus rosa-sinensis Cheerleader Cerise Dark Eye have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Tropical Hibiscus are sensitive to high levels of mineral salts from tap water or excessive synthetic fertilizers. When these salts build up in the leaf tissue, they cause osmotic stress, leading to localized necrosis at the tips.
Hibiscus 'Cheerleader Cerise Dark Eye' requires consistent moisture to maintain cell turgidity. Fluctuating between bone-dry soil and saturated conditions causes the delicate leaf margins to desiccate and turn brown.
As a tropical species, this cultivar thrives in high humidity. In dry indoor environments or during winter heating seasons, transpiration rates exceed water uptake, resulting in tip burn.
If the roots are compromised by overwatering or poor drainage, they cannot transport sufficient water to the leaf extremities. This lack of hydraulic pressure manifests as browning at the furthest points from the stem.
