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.
Although they are most spectacular in spring, part of the attraction of dogwoods lies in their year-round beauty. They are truly a four-season plant, displaying rich green luster in the summer followed by deep red leaves in the fall. Bright red clusters of seeds decorate the tree in the winter months.
