Why does your Cordyline fruticosa have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Cordyline fruticosa is a tropical plant that requires high ambient moisture. Dry air, often caused by air conditioning or heating, causes the leaf margins and tips to desiccate and turn brown.
Excessive buildup of salts from tap water (like fluoride or chlorine) or fertilizers can burn the sensitive leaf extremities of Ti plants. This often presents as necrotic brown tips even when watering is correct.
Allowing the soil to dry out completely between waterings causes moisture stress in Cordyline. This physiological drought leads to the death of the furthest extremities from the vascular system, which are the tips.
While dry tips are common in low humidity, overly saturated soil suffocates the roots of the Ti plant. Damaged roots cannot transport water to the leaf edges, resulting in brown, dying tips.
