Trees add beauty and value to a property, and paving over their roots can put them at risk. A tree’s roots provide it with all of the nutrients and water the plant needs to survive, as well as air, so burying them in concrete or tar will impair the tree’s health substantially, or even kill it.
How close to a tree can you pave?
Paving should be kept out of the dripline and no closer than 15 feet from the tree trunk. If at all possible, use a porous paving material such as brick with sand joints, open bricks, bark, gravel, etc., which will allow some water penetration and gas exchange.
How do you landscape a tree with exposed roots?
Cover them with mulch or wood chips
Mulch or a wood byproduct is the quickest and easiest way to cover exposed tree roots. Rim the circumference of the tree with a three to five-inch high strip of edging or brick. Once in place, cover the roots with three to four inches of mulch or just enough to cover the roots.
Can you put in a driveway around a tree?
In general, the taller the tree, the further away from the driveway it should be planted. Small trees that won’t grow more than 30 feet tall can be planted as close as 3 feet from the pavement. Medium-size trees that grow to a maximum average height of around 50 feet should be located at least 6 feet from the driveway.
How do you get rid of roots without killing a tree?
So, if your tree has a diameter of 3 feet, only cut tree roots 15 feet away from the tree. Mark the area you’ll cut, and dig a hole all the way around the root until it is completely exposed. Use a pruning saw to cut the root cleanly. Carefully pull the cut root up and away from the tree until it comes out.
Can I put pavers over tree roots?
Surface-level tree roots can reach the pavers themselves, or large tree roots deep in the earth can shift the ground under your patio and cause pavers to rise, sink, or crack. However, even though these backyard regulars are longtime foes, pavers are still one of the best options when installing a hardscape near trees.

It’s healthier for a tree to be surrounded by mulch than by grass. Don’t pile mulch against the bark of a tree; that can lead to rot or disease. Always spread it evenly.
How do you lay pavers around a tree?
Allow about 1 foot of horizontal space around the trunk for every 10 feet of vertical height of the tree. This gives the roots room to grow and breathe under the soil. A tree that will grow as tall as 30 feet needs about 3 to 4 feet of space between the trunk and the ring of pavers.
How much root damage can a tree take?
If enough of the root system is destroyed or detached, the tree will die. As a general rule, 20% of the root system can be destroyed before the tree will show signs of injury. If 40% of the root system is lost, the tree will probably die.

Keep in mind that as the tree matures, the concrete will likely crack.
How do I protect tree roots in my driveway?

DON’T crowd the tree with a deck or patio.
The inside border of a patio (because it’s solid and will block water and air) should be three to seven feet (or more) away from the tree to give the roots plenty of surface area to absorb water. Plants or rocks can be used to landscape the space nearer the trunk (see above).
How do you stop tree roots from damaging concrete?
Some effective methods are:
- Putting down a layer of pea gravel under the new concrete allowing the roots to expand.
- Reinforcing the concrete with rebar so the roots have to lift several slabs at once to cause damage.
- Creating a sidewalk that bends or slopes around the tree, giving the trunk and roots room to grow.
