Thanks, Paul, I'll have to consider that when I cut it up. Some of the stubs are pretty big (about 6" long and 2-3" diameter), but the pockets could be useful for bigger orchids.

Thanks, Roberta. By the way, it's a Cyathea medullaris (Black Tree Fern). It has very large coarse frond stubs at the trunk, which might limit the usefulness of the outer part. But I guess I'll find...

Harvesting dead tree fern

Grrr...

Raccoons seem to enjoy playing with my outdoor orchids, ripping them apart looking for bugs maybe. Cymbidiums are too big for them, fortunately.

I use a Brother PT-H100 printer, which is about $20. The printing doesn't fade, it's perfectly legible, and for making more than 2 or 3 labels it's faster than writing by hand.

I've never seen any at TJ stores here in San Francisco. For one thing, they're not very forgiving of unfavorable environments, and if they aren't kept moist they'll croak pretty quickly.

I grow mine as a houseplant 70-80F days, 60-65F nights, ~50% RH, mix of potting soil and fine bark (sphagnum is OK too), moist but not soggy, very low light ~100-200 ft-candles.

I had those once before, but I don't know what they are. One dunk in Bayer Insect Disease and Mite Control (imidacloprid) got rid of them completely.
