The color is not as dark green as it used to be and some of the branches are stunted and some stopped growing leaves. There are dead and dieing leaves on the ends of the branches also. I do not want to lose a 60 year old tree. I need advice quick!!
Chlorosis gets its name from the lack of chlorophyll, the pigment responsible for healthy plants' green color. When chlorophyll is not present, the resulting color is usually yellow. The major cause of chlorosis in landscape plants is a deficiency of either iron or manganese. Both are considered to be plant micronutrients, meaning they are needed in small quantities by plants.
Hope it helps, and hope your tree gets better! =/
