Hi every one at O.B. I've been growing orchids for about 25 yrs. My collection has a fairly wide range. I like to concentrate on species. Every thing from leafless dendrophylax to vanda. My paph fairrieanum which I've had for about 5-6 yrs. has developed scale. It still grows and flowers well, so I would like to eliminate this pest as safely as possible for the plants health. thanks for the help.
