Tree question: I got a quote to have a very large tree trimmed (high up dead branches trimmed & some large "widowmakers" cut down). Quote included, and of course says tree needs, deep root fertilizing. Has anyone had this done? Whole job is just under $1,000, and almost $400 for the fertilizing alone. I'd sure appreciate hearing from anyone who has had this done & if this company's price seems high. Thanks in advance.
