Q.tree shoots or suckers in our lawn
We have what appears to be tree shoots or tree suckers throughout our yard. Every week we mow them down but they don’t die and seem to be everywhere. Is there a product we can use to kill the shoots, but not the trees? The trees in our yard are crab apple, pin oak and a maple.

Single stem young saplings can simply be cut off at ground level and they will die. More established saplings that have already branched will need to be cut off and their cuts painted with Roundup to prevent them from regrowing.
