Can American bittersweet roots cause damage when planted against a house?
I planted an American bittersweet next to my front entry about 7 years ago for the eye catching attraction and not realizing just exactly how big they grow. This year I have noticed that some of the outside cement plaster at base of my house is crumbling and the maple floor boards near the front door entry inside my house are warping - is it possible that the bittersweet roots are under my house and pushing up my floorboards? If so, then what?
