Just Natural Organic Soil Conditioner is basically a composted bark fine that makes a wonderful top dress for your landscape beds. It is easy to apply and does not float away in a rain event. The largest pieces are about thumb nail size. After the season, you do not have to remove this product. It can be turned into the bed as a soil amendment without interfering with the ph balance of the bed. Once you try this product, you won't go back to mini pine bark nuggets.
