Problems with phalaenopsis orchid - Yellow leaves and blooms dying

[stefpix]

I agree with King -
now i have a few dendrobiums and i guess will have t to see which ones go dormant and which ones not.
But my point was that those mass market Dendrobiums are sold potted in bark or coconut slabs.
if the Phals at the same store on sale on teh same shelf would be sold potted in the same media they would have more chances. Usually the more upscale the florist the more moss i see in an even larger pot.
more money more moss same Phal that you can but at Home Depot.

Anyway the Dendrobiums from costafarms or kerry's are usually Dendrobium phalaenopsis from Thailand - so probably can be cared more or lessas Phalaenopsis...
anyway i was looking for a couple of pieces of birch firewood to mount my box store phals. I mounted one on half coconut husk and hung it sideways like phals in the wild.
oconut husk is great because once dry you can open some cracks and sticks the roots in the fibers...

Anyway, I wonder what is this moss fixation with expensive florists...
