This Oncidium Tsiku Maguerit CT Romantic Fantasy is very close to blooming but I noticed mold is growing on the bark and roots. Gadzooks! Am I in trouble here? What should I do?
Don't worry. That kind of mold attacks dead organic matter. The commercial growing cycle of these leads to the medium being very old at the time of first flowering. If you water a few times with chlorinated tap water it may knock down the fungus and will not harm the plant.
Repot after flowering, when new shoots form.
