Why does your Dracaena marginata have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Dracaena marginata is highly susceptible to root rot if the substrate remains saturated. Excess moisture causes roots to suffocate and decay, preventing water uptake and leading to systemic yellowing of the leaves.
Insufficient light prevents the plant from photosynthesizing effectively, causing older leaves to lose chlorophyll and turn yellow. Conversely, sudden exposure to intense direct sunlight can scorch the red edges and cause yellowing.
Dracaenas are sensitive to fluoride and minerals found in tap water. As these salts accumulate in the leaf tissue, they cause yellowing and eventual browning of the leaf margins.
A lack of nitrogen prevents the production of chlorophyll, resulting in a pale, uniform yellowing across the entire leaf surface, often starting with older growth.
