Customers use (untreated and unscreened) whole tree chips in Livestock Paddocks to help control mud and are great for erosion control on steep terrain. Wood chips are also placed to control woodline brush and can help with Tick control. Whole tree wood chips are also a visually pleasing method to maintain woods trails. While contractors sometimes use wood chips for Truck/Construction access matting for sensitive, wet areas. NOTE: Whole tree chips are fine for use under blueberry bushes and shrubs but are not recommended as a substitute for landscape mulch used in flowerbeds.
