How Do You Kill Arborvitae Roots

Paint the surface of the fresh cut stump and the cambium layer with the glyphosate herbicide solution. Apply the herbicide within a few hours of cutting the arborvitae or immediately, if possible, for best results.

What kills an arborvitae tree?

Most often, arborvitae trees brown and die due to either over-saturated soil or extreme drop in temperature. Another potential reason for your tree dying could be due to not having enough sunlight. Each tree is different, but arborvitae generally doesn’t do well in extremely cold or overly shaded environments.

Will arborvitae stump grow back?

Arborvitae can sometimes re-sprout even after being cut back severely, and the wood, while soft, is fairly resistant to decay. This means you may be waiting quite a while for nature to take care of the problem for you, even if it doesn’t manage to regrow its top.
