Our black lava rocks are perfect for a variety of plant care applications. They can be used as soil additives or top dressing for succulents, cacti, bonsai trees, orchids, and more. Additionally, they serve as an excellent base layer or decorative element in aquariums, terrariums, and fish tanks.
These lava rocks are 100% natural, with no added dyes. Their color stays vibrant over time, and even during long-distance transportation, minimal dust may be present. However, this dust does not affect the usability of the rocks.
The porous volcanic rocks provide exceptional drainage for your plants, helping to keep the soil moist and prevent waterlogged conditions. They add weight to your plants, enhancing stability and support.
Before use, it is recommended to wash the volcanic rocks to ensure cleanliness. Rinse them with warm water 3-5 times until the surface is smooth and clean. When damp, the lava rock gravel will darken, ensuring a natural appearance.
Our package includes 10 lbs of black horticultural lava rocks, packed in a resealable ziplock bag. The average size of the lava rocks measures 0.2" - 0.3" (5mm - 8mm).
