best way to kill grass round tree trunks
Trying to mow grass under a tree can be a challenge. You have to dodge low branches and avoid visible roots because the mower blade can carve into them and damage the tree, and the mower as well. The same is true of a string trimmer -- touch the trunk or roots with the string, and you chop away bark and wood.hoose a day that's not windy. Glyphosate won't hurt most trees if it touches the bark, but any that drifts onto the leaves can kill them. If enough gets blown onto the tree, it can kill the tree. Glyphosate doesn't leach into the soil, according to herbicide manufacturer Monsanto, so it's safe to spray beneath a tree.
