We asked our certified arborists what shade trees they would recommend.
Over 133 years ago, Dr. Joseph T. Rochrock documented Pennsylvania’s largest and most magnificent trees. His purpose was to increase the public’s awareness and interest in the importance of trees to our well-being.
In wet weather, a fungus can more easily infect the needles of the trees for an extended length of time. The temperature and air moisture level are two factors present during the spring growth period that determine how well a fungus will grow, and the severity of an infection for each tree.
I remember, as a child, visiting friends who had moved from our old leafy neighborhood in Northwest Philadelphia to new homes in the Northeast. I was shocked by the glare of the summer sun on the bare streets and sidewalks.
