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.
Selecting where to plant your dogwood: Choose a site for your dogwoods that is well-drained but does not get extremely dry. Soil high in organic matter is best. Dogwoods can be planted in full sun or partial shade, though partial shade is best (morning sun in particular). Dogwoods are typically an understory tree in the wild. Dogwoods are easy care trees that will likely bloom by their second year, but sometimes will bloom in their first year. Planting your dogwood: Before you plant, cut off any damaged roots with a sharp knife, and soak plant roots in water for 3-4 hours.
