Whether you’re trying to lighten up a heavy container or want to save on potting mix, this new product is a great solution. At 1½ inches thick, one layer is usually enough for small containers. In larger containers, you may need several layers. Better Than Rocks is:

• Made of 100% recycled plastic and looks like a furnace filter
• Designed to hold soil in but still let water flow out of the hole in the bottom of the container
• Washable and reusable for years to come
