Environment
Optimal conditions for rose powdery mildew are 16-27 degrees Celsius, with the optimal temperature for fungal growth at 23 degrees Celsius in a shaded area. They also do not need water to germinate and infect the rose. In fact, if there is too much water present on plant surfaces for a prolonged period of time the fungal growth is inhibited and the spores can actually die. Rose powdery mildew can also grow in any conditions where roses can grow and has been found everywhere from China to the United States.

“Maturity involves being honest and true to oneself, making decisions based on a conscious internal process, assuming responsibility for one’s decisions, having healthy relationships with others and developing one’s own true gifts.

—Mary Pipher (20th century)
