First let me say that I enjoy our show, found your site and enjoy it too. I'm not a home owner but rent a place in a small town. Some years back, before my time here, the owner was forced to cut some tree's down and left the stumps at ground level. These stumps have been busy underground all those years and are now poping up as treelets all over the yard. I don't even know what kind of tree it is but every year I have to cut several of the invaders back to the ground. I'm not totally sure if these roots are the cause of the leaky roof the house had a couple of years back, as I have noticed some settling at the center of the house. The tree's were in the back yard withing 10 feet of the house and there is a retaining wall about 6 feet from the front of the house. The treelets have started breaking the surface there. They have nearly killed 3 of the bushes and a cedar tree next to the front of the house.

The stumps are breaking down in the back yard.

I know the easiest way; the costly way is for me to move.
Is there anything that I can do to eliminate unwanted tree growth.
