An average tree has as much of a significant root mass beneath the ground as it has above. Most of the mass of the root system of a tree is in the upper 18-24 inches of soil. The roots can spread as far as the most distant tips of the branches while those with invasive roots can spread much further. If you are wondering what trees have the least invasive roots, you should read further.
Remember that invasive tree roots can be destructive. The roots can invade pipes since they have the chief factors to support life – air, moisture, and nutrients. When pipes develop a leak, the roots will seek out the source of the water and grow into the pipe. Roots that move through the pathways and pavements are also looking for moisture.
It is important to note that not all trees are suitable for residential properties. With this in mind, you should learn more about the ideal trees to plant near your house with non-invasive root systems. Problems with the tree roots that will affect your house depend on the overall tree size.
What Trees Have the Least Invasive Roots?
Problems with the tree roots typically come down to the size of the tree. If you are eager to add trees to your property, a key factor I strongly suggest is to begin at around 8 to 10 feet away from any structure for small trees and increase the distance when considering the mature stature and span of the tree.
If you have been eager to learn what trees have the least invasive roots, you can choose from any of the following. Aside from the non-invasive root systems, these trees impart an alluring element to your property.
Crabapple is the ideal choice if you are looking for a tree with a non-invasive root system that also boasts a thicker, rounder, and fuller appearance. It is a deciduous tree that showcases bright pink to burgundy blooms and prefers moist soil as long as there is adequate drainage.
The tree boasts resilience to some of the common diseases that affect apple trees, such as apple scab and fire blight. Crabapples are vibrant and fragrant during the spring and mature in the fall and winter.
The root system of a crabapple tree is non-invasive and non-aggressive that will not bury deep down in the ground and cause the formation of cracks in the pathways or sidewalks. Additionally, you will not worry that your home will be threatened by the tree roots that are searching for sources of water.
2. Trident Maple
The Trident Maple is a resilient and strong tree that works well in urban landscapes but has a steady growth rate. The tree is the best choice for properties that receive adequate sunlight. The tree can tolerate the elements present in any urban landscape including wind, air pollution, salt, and even drought.

Make sure that you will plant this tree under full sun or partial shade.

I suggest pruning the tree and train it to become a single-stemmed form.
4. American Hornbeam
The American Hornbeam tree has a compact form that fits perfectly in any home. The tree boasts resilient wood which rarely splits or cracks. As small trees, they have a variety of purposes on your property.

If you are going to plant the Japanese maple in a warmer environment, the leaves will lose their red or purple color and turn green.

It means that if the roots could not expand once it is planted, it will discontinue upward and outward above-ground growth.
