Have you ever been on vacation and wondered why that beautiful tree or plant won't grow here in Pittsburgh? It's not all about the weather. In fact, although the USDA classifies Pittsburgh as "Hardiness Zone 6," it also warns that other factors are important when deciding what to grow. Light, moisture levels, humidity and the length of consecutive cold days also plays a role. To understand the many factors that go into investing in plants and trees for you home, you should talk to an educated and experienced landscaper, like Hecht's Landscaping and Design. If, however, you are looking to do research on your own about the best plants to choose for this area, Better Home and Gardens Magazine offers a wonderful website; simply type in your zone and see what may work. Once you have compiled ideas, we look forward to discussing if they will thrive in Pittsburgh's environment and how to best incorporate them into your outdoor living space.
