Positive | On Dec 3, 2013, Rickwebb from Downingtown, PA wrote: Gray Birch is not quite as ornamental as other white-barked birch species, but it is still a pretty plant. It grows in an irregular fashion or habit. It is fast growing, about 2 to 2.5 ft/yr. It is relatively short-lived for a tree, about 30 to 50 years. It does not get Bronze Birch Borer because it can tolerate heat over 85 degrees F. A lot of Gray Birch have been planted in southeast Pennsylvania; more than Paper Birch. It is definielty good for USDA Zone 6b in southeast PA and seems fine in Zone 7a in Delaware. When it gets old, the bark on the lower trunk does get grayish. There are lots of wild trees in the Poconos and northeast Pennsylvania. |
