Pittsburgh, Pennsylvania surprised me. The city has a whooping 42 percent tree canopy! In comparison, Washington DC has 36% and Portland, Oregon in the wet Pacific Northwest has mere 30% tree cover. Even Canadian cities known for their leafy nature have less tree cover– Toronto 33%, Vancouver, Ottawa, and Montreal all at 20% tree cover. But enough about trees!
Another visual surprise is Pittsburgh’s topography. Hilly. Steep slopes. It’s a great place to see how gardeners tame their slopes. Since there’s too much information to cover in one blog, I’ve divided it this entertaining topic into three blogs.
