When used, germs [on a dirty washcloth] are then spread or reintroduced to the skin, which can cause irritation and even infection. To minimize the growth of bacteria and mold, hang the washcloth so that air circulates around it, drying it faster.
Dogwoods could live to be 60 or 70 years old, providing they stay healthy. I know of some that are probably 40-50 years old now. Unfortunately, they have many maladies. They suffer from Downy and powdery mildews, which coat the leaves reducing sunlight, slowly choking/starving them to death.
Inside the tree, they feed on the cambium, which is where water and food-carrying structures of the tree are produced. If the cambium is destroyed, branches or the entire tree will die. Leaves of dogwoods infested with the dogwood borer will often turn red and drop early. Bark sloughs off around holes on the trunk or branches. In late summer, a brown sawdust-likeborer frass (insect waste) may be seen near or below the holes.
