I am a student at University of Tennessee at Martin. I am a Landscape Design major. I have a mid-term due in a Landscape Management class, my question involves tree and shrub management. The question in the paper is, as a landscape manager I have come across a job where the area is suffering from unknown non-infectious tree problems. After making a visit to the site I have to come up with the solution within 30 days. Any personal insites or hints that would be of help to me I would appeciate it very much.
