as long as it is planted in a place where the wind doesn't blow. Seriously, it's her place and her tree. She can do what she wants. However, one of the purposes of this board is advise and, hopefully, the advise is based on knowledge and experience. It's a heck of a lot easier to get rid of the willow tree now than when it gets bigger and really becomes a problem. There are many good trees, linden is one example, that are cheap and friendly. There are many more that offer great interest like blossoms or good winter color but usually are more expensive. I would just like to see her really look at the options and chose a tree with assets instead of a "moocher" tree that will eventually cause problems.
