Customer called me this morning and left a message indicating that the Leyland Cypress we installed in mid April is now browning. She wanted to know what to do. A few things come to mind that would cause this. First, the tree may not have been adequately watered. Second, roots damaged upon installation. Third, improper installation. Finally, some type of disease or stress on the tree. The tree is 10-12 ft. tall..Good size. Is there anyway to diagnose the tree and save it?
