After lopping off their heads a few times with the lawn mower, they

from sprouting?


It most likely would have little to no effect, because most
pre-emergents used on turfgrass have no effect on woody weeds. Same
goes for post-emergent lawn weedkillers. Mowing is the simplest way to
deal with them. If you were really consumed with the desire to deal
with them, you could look for a growth inhibitor to spray on the tree
to keep the seeds from forming. See

They have spray stuff for suckers. Would that work?
