Few questions. 1st off, What's the best way to prune sago palms to keep them healthy? next what about tall palms. 24 ft ladder and 12 ft pole saw is barely getting it. have you guys heard of anyone climbing it like the power guys climb power poles, spike shoes and a strap and useing a hand saw? last, all the ends of the branches against the trunk of the tree can be pulled or shaved off pretty easily, is that bad for the tree?
