I recently made my annual visit to my grandparents' graves. While there, I couldn't help but notice that the plant that my great-aunt had planted by my great-grandparents' grave was overgrown to the point of having moved the (insanely heavy) grave marker. I think it's time for this bush to go, and my dad agrees with me.
My dad removed a lot of the small branches with a hedge clipper, removed all the small branches at the top; however, we could not hack through the heavy, thick "trunk" of the bush. (see picture)
So, we have to find some way to get rid of this overgrown trunk. The logical thing to do (I assume) would be to dig under the thing, and take it out from the roots. However, Jewish law proscribes digging into the ground under a grave (besides for the fact that I don't really want to.....).
What can I do to get rid of this plant, without digging?
