my moms house the neighbors down one house has scrub bushes/vines etc. hanging over 5-6 feet into the yard unable to mow down there. A few years ago they did a good job cutting them all down but left the roots. 2-3 years later they are back up and annoying as ever. If going to go thru all that work a whole 60 feet or so 10 feet tall why not dig up the roots and do it right vs. scalping them down few inches up from the ground?
I feel like cutting them down and tossing the remnants onto their own property to see how they like it?
