There is a product called Superthrive that appears to do a good job
stimulating new root growth. Be careful not to overdo it -- too much can
cause deformed new growths in the next season. This used to be readily
available in many garden centers, but lately I have had trouble finding it.

DynaGrow sells a root stimulant called K-L-N which we have also used with
apparent success [no controlled studies, just my eyeball appraisal].

Good growing,

This query relates to my D. carronii query. If root
disturbance/maintenance may be a serious problem, are there any
preparations that specifically promote root growth in orchids?
Similar to the concept of cutting powders to stimulate growth of roots
with garden cuttings. I'm reluctant to dive in & use such a powder on
an orchid I have only just acquired after lusting for it for so long.
