Hi, i have 3 orchids in the conservatory all together,2 are ok budding up and in flower but 1 is budding up turning yellow and dropping off.They are all treated the same and i am puzzled, is there anyone with an idea as to what is causing this.

The buds drop off if the plant has been stressed by being too dry or too cold recently

(Not necessarily right now)

Are they Phalanopsis ?

HI Sunshineband, thanks for answering yes they are Phalanopsis I do try to keep my eye on them with the watering but I did move them about 4 months ago that may be the answer.Thanks again

They also don't like overwatering or draughts
