Took about an hour and a half… I got a telescoping trimmer last year. Got me almost to the top. Still had to go a few steps up a ladder to crown it. Breaks over. Time to get the wheelbarrow and clear the clippings befor I go to paid work.
I have a pole trimmer too. Worx GT. It is a bit heavy and it gives your shoulders and arms a work out but there's no way to trim the middle of mine. They need to come out but the house would look awful bare until new bushes would grow.
