When I was gardening we used to do a 12' tall Yew hedge at one of the houses. It was about 30' long across the front of a walled garden and was sided up and the top squared off every year. We didn't refuse to do any of it because we weren't "tree surgeons". Why did your man set on tree surgeons to do a gardening job. I read your tirade in the original post and come to the conclusion you just like to have a rant. Did they do what they were asked ? Yes and you say they did a shoddy job yet you have to go and fix their otherwise tidy work as a favour. Why do you get yourself involved and worked up over something that is not your problem?. The landlord should have been there or told them exactly what he wanted and if he isn't happy with the job he should get them back to finish it. Some landlords suck, some tree surgeon/gardeners suck and if you're lucky you might get a woman that does if that is your inclination
Yesterday I fixed a neighbour's pressure washer just for a thank you. A repair shop told him it was not worth it, they probably suck as well but I didn't think to post a rant about it anywhere. I'm retired and don't mind helping anybody out and it only took me about an hour. He's a friend and we have been neighbours for 30+ years and I would rather do anyone a favour than a disservice, just get on with it and calm down and stop posting your rants as you know how it's going to end. Think of butterflies and calm blue oceans before you start typing your thread titles and remember that if you can't say something nice sometimes it's better to not say anything at all.
