Carol, I looked up your new orchid and see is is a synonym for Den. harrisoniae. I also found this interesting tidbit:
GROWING MEDIA: B. harrisoniae grows well mounted on slabs or rafts if
high humidity can be maintained and sufficient water can be provided.
Medium sized fir bark produces good results for most growers who use pots.
Successful growers suggest that these plants grow well in a potting mix
more like one used for Paphiopedilum than one used with Cattleya. They
further indicate that fir bark with a little coarse sphagnum and some
perlite added produce excellent results.
MISCELLANEOUS NOTES: Because these plants are intolerant of being
disturbed once established, repotting should be done only when necessary
and then only when new root growth is starting. When dividing, each
division should consist of 4-5 pseudobulbs. Growers report that they have
never found what initiates blooming, and that some plants never bloom.
Whether or not they were providing the conditions indicated above is not
known.
Good luck,
Jim
