Worried about overwatering? Have the perfect planter...without a drainage hole? Our Lava Rocks are your solution. Because of their porous nature, they absorb excess water and slowly release it back into the soil, protecting your plants from their biggest threat: root rot. Even if your planter has a hole, lava rocks are a great addition to any potting mix for added absorbency and aeration.
Our lava rocks are ready-to-use right out of the bag—just add a layer to the bottom of your planter. These 2-quart (1.7L) resealable bags are available in packs of 2 or 4. Please remember to recycle!
