Hi All,

My Potted Mahachanok mango tree is suffering from gummosis. I've stripped the afflicted bark and painted the trunk with an interior latex paint. The paint helps locate the area that persist as it oozes with sap. I just removed that area and paint over it. Is there any thing else I can do to save my tree? Also the leaves are a bit yellow what nutrients are missing?
