Trees that Heave Patios & Walkways
Getting ready to plant trees? Near a deck, patio or pathway? Here are some general guidelines to allow for adequate space root growth: (All info. from: Roots Demystified, change your gardening habits to help roots thrive.)
- It’s best not to plant trees between paved areas with less than three feet of soil to grow.
- Use trees that mature at less than 30 feet tall when you have a space with three- to four-feet between paved areas, such as between a sidewalk and the street next to a patio or foundation.
- If you’re lucky enough to have a space of five to six feet between paved areas, you can plant trees that mature as high as 50 feet tall.
- With trees higher than 50 feet you’ll need at least eight feet between paved areas. [Prepared by Sherry Rindels, Department of Horticulture Iowa State University, Ames, Iowa.]
