A layer of bark under lfs

The remainder is filled with chopped live LFS ..........The redwood (cedar would work as well) has a natural antiseptic quality that discourages anaerobic processes, and this is reinforced by the use of live sphagnum as a medium.

here: Regia Topic

I found some bark out in our garage that we used for mulch in our garden and I was wondering if this would have the same effect. I'm not sure what kind it is, and it doesn't appear to say on the bag, it just says, "Supreme Walk-on-Bark". This is my first D. regia and am looking forward to transplanting it in a nice big pot of pure LFS and hopefully the right kind of mulch at the bottom.

My experience is with using "chopped redwood bark" for this purpose. I would be quite reluctant, to say the least, with any other bark or bark byproduct. They may work even better than "chopped redwood bark", but I cannot recommend them. I have only ever used "chopped redwood bark". It works very well, and lasts for many years in this situation.

Chopped redwood bark is distributed for use as an ingredient for orchid culture. I obtained mine about 25 years ago from J. T. Dimmick, Forest Products Company. It is available from several nursery supply companies.

Here are some suppliers:

Actually, I believe most orchid mixes are fir bark, as are a goodly portion of all "walk-on" type barks. I think the most popular redwood product are "redwood chunks" or something to that effect.
