What tree can I plant next to a wall?
Certain tree species have less invasive root growth, making them ideal for planting near retaining walls. Examples include Japanese Maples, Dogwoods, and Ornamental Grasses. These trees tend to have compact and less aggressive root systems, reducing the likelihood of conflicts. Ficus trees, for example, have very aggressive root systems and even a small ficus tree planted close to a structure could cause foundation damage. Oaks and maples have massive root systems, but actually may cause less damage because their roots generally go around obstructions rather than through them.
