This 15oz bag of Mixed Lava Rocks contains all-natural, organic lava rocks that make the perfect soil amendment for pots without drainage holes.
These rocks should be placed at the bottom of the pot underneath the soil so any excess water can pool away from the roots. The porous rocks will absorb and then slowly release excess water to keep the soil perfectly moist.
Size: 15oz Bag
The Lava Rocks create excellent drainage and root aeration.
