I have lots of time I think. We planted a London Plane tree in the front yard for shade, it will take 50 years to reach mature size, and by then it will be too big for the yard. Of course, I will be long dead by then and won't have to worry about it. Hubby wanted it, when I eventually saw the mature size I said, "What the heck did we plant that one for on our 1/3 acre lot???". He is allowed to voice his wants, as they are often denied. Hey, he can park a road grader in our yard if he wants.
