The majority of oak tree roots grow in the top 18 inches (45 cm) of soil. These roots spread laterally from the tree, 3–7 times wider than the spread of the branches. The deepest root of the oak tree is the taproot, which typically grows straight down beneath the trunk to a depth of 3–5 feet (1–1.5 meters).
- The majority of the roots that support your oak tree are within the top 18 inches of the soil. The only oak root that grows downward is the taproot, which grows straight down into the soil, typically to a depth of 3–5 feet. Oak roots grow mostly outward, not downward.

How deep are the roots of an oak tree?
Most oak tree roots lie only 18 inches under the soil. They may spread, though, to occupy a space four to seven times the width of the tree’s crown. Root hairs, located just back from the tips of the smaller roots, absorb water and minerals and send them circulating through the root system.
Do oak trees have deep tap roots?
The slow-growing trees grow in most regions of the United States, from coastal southeastern states to the Pacific Northwest. Oak trees develop deep tap roots. An oak with a healthy root system can grow into a majestic, round-crowned shade tree.
How deep is a tree tap root?
Trees must spend their energy developing a diverse root system. In some trees, the taproot will only end up being about 3 feet deep, while the other roots, which grow out of the taproot, grow much further out and down.
Which oak trees have tap roots?
White Oak has a tap root that grows beneath the trunk in soil that drains well, but this is not present on most trees planted on clay or compacted soil. The availability of new nursery production techniques to control root growth should help growers of nursery plants make more of these native trees available.
Do oak tree roots grow out or down?
The majority of the roots that support your oak tree are within the top 18 inches of the soil. The only oak root that grows downward is the taproot, which grows straight down into the soil, typically to a depth of 3–5 feet. Oak roots grow mostly outward, not downward.
How close can you plant an oak tree to your house?
This question all comes down to tree size. After all, the wide-root oak tree that’s 70 feet tall needs much more room than the modest Japanese maple. A good rule of thumb is to start at about 8 to 10 feet away from your home for small trees and scale up to account for the tree’s mature height and spread.
What causes oak tree roots to grow above ground?
These roots have feeder roots growing off of them. Both types of roots take in oxygen for the tree. Oaks and other trees often send roots above the surface for greater access to oxygen. Covering these roots incorrectly will only starve the tree and lead to issues with rot.
Are oak trees bad for houses?
Unlike pine trees, oaks and elms have shallow roots which can potentially damage your foundation. They tend to grow pretty quickly – a trait that makes them extremely popular. They grow quickly because they drain a lot of water from the soil. Without proper maintenance, this may require foundation repair.
Are silky oak tree roots invasive?
Silky oaks have been declared an environmental weed in parts of New South Wales and Victoria where it grows outside its native distribution range. They’re also considered an invasive or invader plant in Hawaii and South Africa.
Which trees damage foundations?
While oaks, poplars, and ash trees are undoubtedly the most common causes of foundation issues, there are many other types of trees that can cause issues. Some are deciduous trees, such as the black locust, boxelder, Norway maple, silver maple, sweetgum, sycamore, and tuliptree.
Which trees roots grow straight down?
Taproots are large roots that grow straight down below the trunk of the tree. Compacted soil makes it difficult for trees to develop such a root. Most trees will never establish a taproot, but instead grow a sprawling network of woody and feeder roots, usually no deeper than 12 to 24 inches.
What trees have no invasive roots?
Which Tree Types Have Non-Invasive Roots?
- Japanese Maple.
- Crape Myrtle.
- Eastern Redbud.
- Cornus Mas.
- Kousa Dogwood.
- Japanese Tree Lilac.
- Dwarf Korean Lilac.
How wide do oak tree roots spread?
Roots of the Oak trees spread up to 3 to 7 times the diameter of the tree’s crown, therefore they need a wide space, not just above the ground but under the ground as well to thrive to their fullest. They lie around 18 inches from the ground.
How do you stop oak tree roots from growing?
To remedy the situation, use the same steps you used while safeguarding your foundation:
- Install root barriers before the roots reach the concrete.
- Cut the roots and dam them with root barriers to prevent further growth.
- Cut down the tree and remove the root system so you can make a smooth, level surface again.
Can an oak tree regrow from a stump?
You may not believe it, but a tree can grow back from a stump and become a full tree. It happens because roots are still present there. The only thing is roots are not active. But its is possible that there are enough nutrients in the roots to regrow the tree by the sprouts sticking to the ground.
