I just bought a house that has two trees in the backyard that I'm told are Lombardi Poplars. They don't give much shade and send out intrusive roots that encroach on the garden, and I'm afraid, my house. I'm thinking about cutting them down (they are about 50 feet tall), but I hate to cut down trees for no good reason. Does anyone have any info on them? Are there any reasons I should NOT cut them down? If I do, are they good wood to burn in a stove?
