Why does your Citrus aurantium have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Nitrogen is a mobile nutrient in Citrus aurantium; when deficient, the plant moves nitrogen from older leaves to new growth, causing uniform yellowing (chlorosis) of older foliage.
Common in alkaline soils, a lack of available iron prevents chlorophyll production, resulting in bright yellow leaves with distinct green veins (interveinal chlorosis).
Citrus trees are highly sensitive to waterlogged soil, which suffocates roots and leads to yellowing foliage and eventual leaf drop due to impaired nutrient transport.
While primarily known for silvery trails, severe infestations on young bitter orange shoots can cause physiological stress and subsequent yellowing of the affected foliage.
