Sawdust
Sawdust can be effective for a soft surface for paddocks, beds and as a blueberry mulch. When used for mulching blueberry plants, paddocks, equestrian arenas, and trails, sawdust can be very effective in lessening the impact of falls or impact strain. Sawdust also controls mud and moisture preventing slips. Sawdust provides an inexpensive, environmentally friendly surface for any area or path.
