Linden Tree ailing

Question

Symptoms of Linden Tree problem. Branches have turned bright brown and are drooping to the ground; the leaves are curled into a cylinder shape; some leaves have a shiny appearance but the ones I can reach aren’t sticky; I’ve checked all the lower leaves and see no insects on them; The tree was planted around 1975 and is huge. Any suggestions on what the problem is?

Answer 1

Cankers are sunken areas of dead tissue that may appear on an American linden’s trunk or branches; they are sometimes very noticeable and other times hardly visible. The leaves on infected branches will turn yellow or brown and wilt; cankers kill branches or stems that they completely girdle. These dead spots are caused by fungi or other factors. To address cankers on branches, prune off the problematic branches as soon as you notice the damage, making any cuts well below the bottom of each canker into healthy tissue and positioning cuts just above stem junctions or next to a branch collar, the area of raised tissue where a branch meets the trunk or a larger branch. Once cankers appear on a tree’s trunk, there is no way to address the canker, but providing the tree with excellent cultural care will prolong its attractive life.
