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.
The height ranges from 15 to 20 feet tall (flowering dogwood in the sun) to 40 feet tall (flowering dogwood in the shade). The spread may be even greater than the height. Growth Rate: Dogwoods grow at a slow to moderate rate (about 20 feet in 25 years).
