Went on a landscape est during the summer and the customer asked me if that was a good idea (pointing to a blue atlas cedar right up against the house). I immediately said no. "The roots will go into the foundation wont they". I said they probably will. Ive also seen Magnolias in the same position. I realize that those plants will have to be moved in 3-5 yrs but I never really heard of any probs. with roots going into the foundation. Have you?
