Trees With Non-Invasive Roots: 6 Trees With Roots That Grow Straight Down
There are so many varieties and styles of trees that when considering which one to plant in your yard the task may seem extremely difficult and burdensome. Not only do you have to decide what look of tree you are after, but you must also consider factors and implications certain types of trees will have. Homeowners must be careful when planting trees because roots can affect things like your home’s foundation and pipes.
Two Types of Roots
Before we go into what types of trees are non-invasive for your yard, it’s important to understand that all trees follow one of these two types of root systems—tap root system and the adventitious root system. For the tap root system trees, roots will grow straight vertically down whereas in the adventitious root system the roots spread and sprawl. These roots spread and sprawl as they search for nutrients for the tree.
Non-invasive roots such as in the tap root system go deep down instead of out towards your house in search of water.
Top 6 Trees with Non-Invasive Roots
Japanese Maple
The Japanese Maple is an Ornamental Tree and is a very popular choice for many yards. These trees are easily manageable and a great solution for smaller yards. They also come in many different colors such as purple, red, orange and green.
Star Magnolia
When this tree comes into bloom, it is a true showstopper for any yard. The stunning magnolias appear weeks ahead of spring and are welcome sign of an upcoming thaw after long winters. You will want to choose a sunny location or partly sunny spot if you are in a really hot climate. The star magnolia grows to a height of 15-20 feet and a spread of 10–15 feet at maturity. The Star Magnolia grows best in acidic soil so it’s best to get a soil sample before planting.
Crape Myrtle
These trees are year-round showstoppers, from their summery flowery bushes to their colorful fall foliage and even in winter with their shedding and attractive bark. This tree also comes in a dwarf variety for those with smaller yards who may be short on space. The Crape Myrtle comes in several varieties from white to shades of red, purple and pink.

3 Trees to Avoid
Now that we have given you some great trees to plant with non-invasive roots, let’s talk about some trees that you should definitely avoid.
Eastern Cottonwood
When thinking about root structure, the Eastern Cottonwood should definitely be avoided. The roots of this tree are shallow and aggressive making this a very unstable tree. If the instability isn’t enough, this tree also produces fluffy cotton seeds that blow off and stick to everything making your yard a complete mess.
Sycamore
When it comes to trees and the term high maintenance, the tree that takes the cake is the sycamore. These trees grow massively large, pair that with their very aggressive roots, and then to top it off add in the dropping bark, the frequent falling seed-pods and the tremendous leaves falling that will litter your yard, this tree is a no-go for most home owners.
White Mulberry
When speaking of aggressive roots, the White Mulberry may be at the top of the list. The roots of these trees spread and become so aggressive they can even crack pavement. These roots grow horizontally as they search for both air and water nutrients. Aside from their root structure, these trees are known to be very messy and emit pollens that can be troublesome for those with allergies.
