Why does your Citrus junos have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Yuzu trees have a high demand for nitrogen during their active growth phases. A lack of nitrogen causes chlorosis, specifically appearing as uniform yellowing of older leaves while veins may remain slightly greener.
In alkaline or high-pH soils, Yuzu cannot effectively uptake iron. This results in interveinal chlorosis, where the leaf tissue turns yellow but the veins remain distinct and dark green.
Yuzu is highly sensitive to 'wet feet.' Excessively saturated soil deprives roots of oxygen, leading to root decay which inhibits the plant's ability to transport nutrients, manifesting as general leaf yellowing.
The larvae of the Citrus leafminer tunnel through the leaf tissue. As these tracks mature, the affected areas can turn yellow or bronze, eventually leading to necrotic spots and overall leaf discoloration.
