Today, I discovered that lady's lawn service tried to prune a tree, cutting branches off a few days before I arrived to complete the work that the lady accepted an estimate for. The flush cuts show a lack of education regarding proper pruning and proper tree care. The bark damage shows either a lack of education or carelessness, since there were several of those bark cuts. The company that did this too, was working out of their class, because Oregon set a limit for cut sizes, above which someone needs a state license. These cuts exceeded that. Not all ignorant yard care pruning exibits this kind of bark damage, buy quite a few exibit improper horticulture, like poorly time crown reduction, or exceeding foliage removal guidelines. Here's questions that various services can chime in on, because some lawn care providers will know how to prune, and other won't... How do you estimate when you are qualified to provide proper pruning, or not qualified? What are your company policies to avoid pruning for which your company is not qualified. If you are qualified, what convinced you that you reached the threshold of proper horticultural pruning? Regarding other lawn companies that you work near, how many go beyond lawn care into shrub and tree pruning with minimal experience or education that cover those needs?
