Why does your Hibiscus rosa sinensis Cheerleader Red Dark Eye have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyExcessive buildup of mineral salts from fertilizers in the soil can draw moisture out of the leaf tissue via osmosis, causing the tips to desiccate and turn brown. This is common in Hibiscus when high-nitrogen fertilizers are used without regular flushing.
Hibiscus 'Cheerleader Red Dark Eye' requires consistently moist but well-drained soil; when the growing medium dries out completely, the plant cannot transport enough water to the furthest extremities of the leaf.
As a tropical species, this cultivar thrives in high humidity; dry indoor air or air conditioning can cause rapid transpiration that the root system cannot keep up with, leading to tip necrosis.
Hibiscus can be sensitive to the high levels of chlorine, chloramines, or fluoride often found in municipal tap water, which accumulates in the leaf tips as the plant transpires.
