how much are you charging to vertimulch? ive been charging 160-300 for trees depending on size... us the verti from phc, peat moss, fert, and compost. to refill with. i have only been using the drill. dont have 2,000.00 for the supersonice knife and another 10,000 for the compressor...
i have had excellent results with this system saved a lot of trees that were in real bad decline from retard home builders that decided to drive the heavy equipment all over the place.
