Why does your Citrus medica have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Citron trees have high nutrient demands; a lack of nitrogen prevents the production of chlorophyll, leading to uniform yellowing of older leaves first.
Citrus medica is sensitive to 'wet feet'; excessive soil moisture displaces oxygen in the rhizosphere, causing root suffocation and leaf chlorosis.
Common in alkaline soils, a lack of available iron prevents chlorophyll synthesis, specifically affecting the leaf tissue between veins.
While primarily known for lesions, severe bacterial infections can disrupt nutrient transport and cause systemic yellowing and premature leaf drop.
