When a growing root tip touches copper it stops lengthening, and the root branches out behind the tip instead of pushing on through. Nurseries use the same effect in copper-treated pots to keep roots from circling. Because the barrier is an open mesh rather than a plastic sheet, water and air still pass through it, so the soil on both sides drains normally.\u003c\/p\u003e\n\u003cp\u003eHow strongly roots respond varies by species and site, and roots can still travel under a barrier that is too shallow. For large or established trees, or work close to a foundation, check the plan with an arborist.\u003c\/p\u003e\n\u003ch4\u003eChoosing a width\u003c\/h4\u003e\n\u003cp\u003eThe roll width is the barrier depth, less the inch or two left above grade.
