Are Landscaping Rocks Safe to Put Around Trees?
River rocks can be safe for trees as long as you choose the right ones. River rocks are ideal for trees because they’re smooth and rounded enough to avoid damaging tree roots. If you live in an area with extreme heat, lighter-colored river rocks are the best choice, since they absorb less heat. The Mexican beach pebble Raleigh homeowners often select for tree borders offers this same light coloring, keeping roots cool in hot climates.
How Deep Should River Rocks Around Trees Be?
In most cases, a depth of 2 to 3 inches is recommended. This is enough coverage to prevent gaps and stop weeds from growing through. At the same time, this level of coverage isn’t heavy enough to cause any issues for tree roots. Avoid using a layer of more than 4 inches so you get proper drainage around your tree.
How Far Away Should You Place Your River Rocks from Trees?
For smaller trees, you can start your river rock coverage around 6 inches away from the tree trunk. For larger trees, you may want to leave 12 inches of soil bare around the tree. The Mexican beach pebble Miami landscapers recommend for tree rings works well within this 6- to 12-inch guideline. This spacing allows you to use river rocks to keep weeds from damaging your tree while still allowing enough airflow around the bark on the trunk.
Should You Put Decorative Rocks Over Exposed Tree Roots?
You can place river rocks over exposed tree roots, but keep in mind you don’t want to put your decorative rocks too close to the trunk. For the best results, choose rounded rocks, clean your tree roots carefully, and gently place a thin layer of smaller river rocks over the roots.
Choosing the right rock, depth, and spacing makes all the difference in protecting your trees for years to come.
