I received some dens from Hawaii in August. They're potted in lava rock and perlite. I've read that the lava rock does not decompose so just wondering if this media can be cleaned and reused when time comes to repot. The roots are all over the tops of the pots and flowers still blooming.

Perhaps they're all blooming now because they were grown in a much warmer climate. Looks like they may remain in bloom for awhile so I'm not sure when to expect any new growth, check the roots and repot, if necessary. At any rate, I'm curious how often the lava rock needs to be replaced or IF it needs to be replaced? Anyone using this media?
