In the previous blogs, I covered the merits of planting up slopes and the visual delight of terraced slopes. But which method works best for your site? How do we decide? According toUniversity of Nevada Coop Extension, the slope angle decides the method!
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.
