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.
Flowering Dogwood (C. florida). Mature Height/Spread: The flowering dogwood will grow 40 feet tall when grown as an understory tree in a woodland setting. In the sun, the same tree may only grow 15 to 20 feet tall and wide. Spread can be greater than height at maturity. It can be grown as a single or multi-trunk tree.
