Has anyone here ever planted leyland cypress for a hedge. If so I would appreciate your input. I have seen suggestions on planting anywhere from 30" apart on up. What is the best planting distance? I know these trees get very large that is not a problem. Just want the best distance apart and maybe from the property line for a nice thick hedge. Also, I have searched and searched and maybe I overlooked this, and I know it is off this subject, but if anyone knows how many cubic ft are in a 40lb bag of cow manure or any conversion from pounds to yds of ft please let me know. Thanks to everyone here at lawnSite. I have learned so much in such a short time. It is so nice to have a place to go to share experience and knowledge. Thanks again everyone.
