To pick the best tree that won’t harm your foundation, it’s important to select trees that do not have an invasive root system that causes problems. Before deciding on a particular tree that you think will be excellent, make sure you find out all about its root system, especially about the anticipated depth and spread of its roots. Trees can destroy your property.
What kind of trees should not be planted near a house foundation?
Trees that grow long, lateral roots should not be installed near house. By growing under your structure and forcing it upward. This can cause your foundation to heave. What’s more, because trees need water to sustain them, they will rob your soil of much needed moisture and this can be damaging to your structure.
As a general rule, it’s best to plant trees that have taproots. This group of trees includes oaks, walnut trees, hickory and conifers. A second group of trees, such as maples, ash trees and cottonwoods, are known for growing invasive, lateral trees roots and are not good choices. Deciduous trees tend to have a deep root system and are best avoided.
It’s important to note that soil conditions also affect the growth of trees roots, too. Highly compacted soils have less oxygen in them and, as a result, roots do not tend to become exceedingly large. Trees planted in hard compacted soils generally grow near the surface of the soil and pose less threat of harm to your property.
How Far Should You Plant A Tree Away From The House?
They should be installed a safe distance away, as possibly as far away as fifteen feet. If you intend to plant a tree that has a large root system, it should be positioned a minimum of 25’ away from your house and 50’ away, if possible. Remember: the spread of tree roots can be two to four times greater than the drip line of the branches. This means that a massive root system can easily form under your foundation.
While roots can harm your foundation, they can cause other problems, too. It’s imperative to keep tree roots away from underground utilities. To be on the safe side, make sure trees are installed a minimum of 5’-10’ away from utilities. Where driveways or sidewalks are concerned, it’s best to plant them at a distance of 6-7’ away if you’re installing a medium-sized tree, and up to 20’ away if the tree is known for having large, encroaching roots. It may be beneficial to install a root barrier to protect your house or driveway from damage.
