Locust Trees, while nice foliage etc., have very lousy surface roots.
Further if you don't cut back the shoots that pop up from these runners,
you'll get a new locust tree with thorns (the primary form). I have been
cutting locust tree roots for years now off my tree and it doesn't seem to
hurt it at all. Also the roots will destroy whatever lawn you have. In
Australia, the locust tree is a predatory tree and is hunted to elimination.

I will try using this brush killer concentrate. Do I have to go to a
special
store to get this?

Thanks for your help....

We recently had several trees cleared from the back of our property. A
couple of them were locust trees. The roots have these tremendously
long
runners that are about the size of a water hose that run under the
surface
of the soil. The tree service told us to keep applying round up
concentrate
at a rate of 4-5 oz. of round up to a gallon of water. Apply every two
weeks until the tree is dead. We actually ended up getting Bonide Brush
Killer Concentrate because it kills woody type brush along with poison
ivy,
oak, etc. My poor husband can attest to that. I haven't noticed any
new
sprouts anywhere.

I had a locust tree in my backyard. We had it taken down because it
was
blocking the sun to one of our favorite beech trees. The tree was
removed
two years ago and we have yet to have the stump ground down. This
tree
was
in a lawn area. Ever since we removed the tree, during the spring and
summer, sprouts of locust shoots are everywhere. The entire root
system
of
the tree is apparent. I have even severed some of the roots, that
were
close to the surface, and I still see these shoots and have to mow
them
down
(they grow quite rapidly). I am afraid that even when we remove the
stump
we will have a problem with the roots. Has anyone experienced this?
