Know before you buy
Orchids require significant airflow around their roots to prevent rot, which traditional soil often restricts. Lava rock provides a porous, inorganic structure that ensures excellent drainage and aeration while still retaining enough moisture for the plant to thrive.
No. Because it is an inorganic material, this lava rock will not decompose or compress, meaning you won't need to repot your plants as frequently due to media breakdown.
While it can be used as a standalone medium for certain orchids, it is most commonly used as a base for custom inorganic mixes. You can easily blend it with other components like charcoal or perlite to tailor the water retention to your specific plant's needs.
A 2-quart bag is generally enough to repot two to three standard 4-inch orchid pots. If you are using it as an amendment in a larger mix, it will go significantly further.
It is good practice to rinse the lava rock before use to remove any fine dust or debris accumulated during shipping. This ensures your potting mix remains clean and prevents the drainage holes in your pots from clogging.
