A third of a long row of our mature privets were really bent over by heavy snow 2 years ago. A landscaper cut them down a few feet and tied rope around them to straighten them, but it has been in place for almost a year with no results. It seems like there could've been a stronger effort to retrain them. The privets are at least 8 -10 feet tall. Any suggestions on how best to proceed?
Thank you in advance.
