Organic Lava Rocks Care & Information
Have a planter with no drainage hole? When placed at the bottom of the planter, lava rocks create a place for excess water to pool away from your plant's roots! Lava rocks have the additional bonus of being porous; they can absorb and slowly release excess water over time.
- Ingredients: organic lava rocks
- Bag contains enough lava rocks to line the bottom of 4-5 small 5” diameter planters or 2-3 medium 7” diameter planters
- Not applicable to discounts and promotions
