Question
My dog got to my Den. inagaki Pink orchid and destroyed the root ball and part of the plants. Is there a way to encourage new root growth?

Thank you

Answer
Debbie, most dendrobium orchids have a rest period before resuming new growth.  If your plant was not producing new growth prior to the accident, depending upon the extent of the damage, you should ensure that it is tightly potted in its pot and then water very sparingly.  If it had new growth emerging at the time the damage was inflicted, you still need to ensure that it is tightly potted but may resume watering and feeding on your regular schedule.  Be sure that any new tissue that is exposed is sealed against possible fungal growth by smearing an antifungal powder (eg powdered sulphur , roottone, etc) on the open wounds.  New roots growth will naturally occur once the plant resumes normal growth in its growth cycle. Roottone can also stimulate root growth but only when the plant is in its growth cycle. Old canes do provide sustenance to new growth so try to preserve those as much as possible.  When the plant is at rest, just spritz the canes from a misting bottle from time to time to prevent shrinkage.
