Yellow spots on Oncidiums

10 years ago

Hi there

One of my oncidiums has yellow spots on the leaves. Can one of you orchid mavens give me a diagnosis?

Thanks

Karen, what oncidium is this? Do you have a name, or photo of the flowers?

Sorry, no help, just the observation that my oncidiums get all kinds of spots. They still bloom though.

The orchid is Mtdm. Red Brick Road Arbec. I guess not strictly speaking an oncidium. My other Mtdm (Bartley Swartz (?) is also showing similar spots but far fewer).

I am hoping that it is not mites or some other horrible pest that will infest the rest of my collection, so I am feeling slightly reassured that your oncidiums get them too. The one with the most of these spots has just thrown up a spike for the first time since I got about 3 years ago

Thanks

Karen
