"tree of heaven" conundrum
We moved into this home this past winter. Through the "name that plant" link on here, I was able to identify this particular tree as Ailanthus altissima, aka, "tree of heaven". I can attest to the invasiveness of this tree, as I have dozens surrounding two sides of my property, most with trunks between 2-4". I've already begun the battle of cutting down, and covering the stumps with herbicide in an attempt to kill the young root systems.
Now here's what has me stumped(pun intended)lol...I have two rather large specimens, approximately 30-40', that are pretty close to the house. They are imbedded in an embankment about 10-15' or so from the front of house. It should be known that, since moving in I've had to spend thousands to fix my basement slab. There were massive voids underneath that caused cracks and heaving and I had to have a company inject polyurethane to fill the voids to support the slab.
TMI I realize, but it looks like these two large tree of heavens root systems "may" have at least contributed to the slab issues, yet they actually look nice where they are, very nice actually. I'm also concerned that if I cut them down, I might stimulate more root activity, doing more harm than good.
Do you guys think these trees, being probably 15 or so years old, will continue to do damage under my slab, or should I have them cut down, and then try go use a stump/herbicide method for killing the roots, OR maybe try the "cut and squirt" method of killing tree first, then cutting it down.
Sorry for the long post. I did say it was a conundrum! Lol
