Why does your Chrysanthemum Barbosa have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Nitrogen is a mobile nutrient; when lacking, the plant pulls it from older leaves to support new growth, causing uniform yellowing of the bottom foliage. This is common in Chrysanthemums during periods of rapid growth.
Excessive moisture in the substrate displaces oxygen, leading to anaerobic conditions that damage the fine root hairs of Barbosa Chrysanthemums. This disrupts water and nutrient transport, resulting in chlorosis.
If the soil pH is too high (alkaline), Chrysanthemums cannot absorb iron effectively. This presents as interveinal chlorosis, where leaves turn yellow but the veins remain dark green.
This soil-borne fungus invades the vascular system of the Chrysanthemum, blocking water flow. This often manifests as progressive yellowing and wilting of stems.
