Why does your Citrus myrtifolia have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
In citrus species like C. myrtifolia, iron deficiency often manifests as interveinal chlorosis, where leaves turn yellow while veins remain dark green. This is common in alkaline soils where high pH prevents the plant from absorbing micronutrients.
Excessive soil moisture deprives roots of oxygen, leading to a breakdown in nutrient transport. For Orange Myrtle, this typically results in uniform yellowing and eventual leaf drop as the root system begins to decay.
A lack of nitrogen prevents the production of chlorophyll, causing older leaves to turn a pale yellow before moving to newer growth. This often occurs if the soil is depleted or if heavy rains have leached nutrients away.
While primarily known for silvery trails, heavy infestations can cause physiological stress to the plant, leading to leaf discoloration and yellowing. The larvae feed on the internal tissue of the young leaves.
