Why does your Citrus sinensis have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Loss of turgor pressure in citrus leaves is most commonly caused by drought stress or root hypoxia from waterlogged soil. While underwatering causes wilting to save moisture, overwatering leads to root rot which prevents the tree from absorbing water.
This soil-borne pathogen attacks the root system of Citrus sinensis, specifically targeting the bark and roots. As the root system decays, the tree loses its ability to transport water to the canopy, resulting in permanent drooping.
A lack of essential nutrients like Nitrogen can cause overall foliage decline and drooping. Iron chlorosis, often caused by high soil pH, prevents the tree from producing chlorophyll, weakening the leaf structure.
The larvae of this pest tunnel through the leaf tissue, creating serpentine tracks. This damage disrupts the vascular flow and structural integrity of the orange leaves, causing them to curl and droop.
