Why does your Citrus myrtifolia have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Citrus myrtifolia is sensitive to dramatic shifts in soil moisture. Sudden leaf drop often occurs when the plant undergoes rapid dehydration or when roots are suffocated by overly saturated soil, triggering a defensive shedding response.
As a subtropical species, sudden exposure to frost or an unexpected heatwave can cause physiological stress. This rapid change disrupts the plant's metabolic processes, leading to the abscission of older leaves.
A soil-borne fungal pathogen that thrives in poorly draining conditions. It attacks the root system of Citrus species, preventing nutrient and water transport, which manifests as sudden wilting and leaf drop.
A lack of essential macronutrients can cause the plant to shed leaves to conserve energy. While usually more gradual, a severe deficiency in nitrogen or magnesium can lead to sudden thinning of the canopy.
