Hi, I need some help regarding a mule ear oncidium problem. Over the years I have seen a number of bloom spikes of various hybrids or species mule ears reach 12 or more inches and then simply collapse or bend in the middle of the spike; ending blooming for that growth. Some do bloom normally. I have been told that sunlight could cause this, doing something to the sugars in the stem, but putting plants in a shady area did not make a difference. Some of those shaded also collapsed.
We have just been through a heatwave and one spike of 4 has now collapsed, but I do not know if it is heat related. The greenhouse was in the 90's during the worst of it. (The evaporative cooler can only do so much with the high humidity present also. But other spikes are still intact. But could something else cause this?
