I’m looking to do a decorative live fedge in my backyard, from the house foundation straight back to the fence. I’ve read that willow should not be used close to houses or cisterns due to their aggressive roots. What else would be suitable for this project. I was thinking dogwood, but I don’t want a thick hedge, and the trees seem to have the potential to become quite large. I’m looking more at a sculptural application to separate a small section of the backyard from the rest, for a little sanctuary. Area to span is approximately 6m (20’) and we will be creating an opening in the fedge to enter this area. hardy zone 5b, sun to partial shade. There are a few walnut trees and an American basswood tree along the fence line.
thank you for your help.
