This plant improved a lot when I potted it in Dendrobium mix I got from Repotme.com
I inherited this mounted and it wasn't happy during winter months.
I also noticed the vivid color of the flowers and the size have become bigger than when I first acquired it.
The canes have also become more plump.
I have to thank Ronald Hanko for introducing me to Ray's fertilizer which might have helped make this plant happy and healthy.
This is a seven year old plant.
