That's kind of strnage that you are beating up on netree for saying that the tree needs to be removed.
All that aside, I can't believe how badly they butchered that yard. All that can be done now is either removing the ceder and putting in a nice flower bed or something, or wait until it dies, then remove it.
I dunno what you're gonna do with that maple. Probably remove it cuz it's a danger to the house now.
That must be a huge disappointment becuse obviosly you love the trees you have noble, and you only have a small property, and there's no way to replace them now.
