Try using coconut husk chunks. They last longer and don't plug up the mix.
Get the medium or large size for larger plants and for any that want a fast
drain but don't like to dry out.

A great culture article K, they call for "chunky peat" in the potting mix?
Anybody know where to get this special chunky peat?

Try this article by Yin-Tung Wang. IIRC it covers the basics.

Den. superbum had one fat active growth with leaves going up it and a
few back bulbs. Then all the leaves turned yellow and fell off and I
thought, great, killed another one. But I kept it around and kept
watering it and lo and behold, it started growing something out of the
top of what used to be the active growth. I figured it was a keiki,
but
no, it is a spike.

Is this normal behavior for this Den.? What do I need to do to bring
this spike to a happy conclusion while keeping the plant alive for
another season?
