The 'Plant dried up' disease significantly impairs the health of Kentucky coffee tree, causing dehydration, leading to progressive browning and eventual death of the plant. This disease caused by multiple factors can be challenging to control but not impossible with meticulous care.

Branch withering

Branch withering is a disease impacting the health and vigor of Kentucky coffee tree, leading to branch dieback and potentially tree loss. It results from both biotic and abiotic factors, impacting plants' aesthetic and ecological roles.

Black mold is a fungal disease that compromises the health of Kentucky coffee tree, leading to reduced vigor, aesthetic damage, and potential branch dieback.

Leaf rot is a common fungal disease that significantly affects the health and vigour of the Gymnocladus dioica (Kentucky coffee tree). It primarily targets the leaves, causing discoloration, wilting, and premature death of the tree if not treated promptly.
