"Q: ... Dendrobium... The potting media... some type of rock/lava material. Where can I get more?...
Answer [Arthur Chadwick] : The best place to get lava rock is... Hawaii... Hawaiians often use crushed lava rock and/or shredded coconut husk in their potting media. Many of their fertilizers are derived from fish and seaweed. ... we have found that the best potting media for Dendrobium orchids in Virginia is fir bark chips -- small size for young or compromised plants and medium size for everything else. Soak the bark in water for 24 hours before use. Combine with clay pots that are slightly larger than the root ball."
