Oncidium help-- Sherry baby sick?

[orchidsamore]

I agree with the nursery's advice, it is the same advice I would give to my customers. The plant does not need re-potting and can last in that pot for quite a while longer.

I grow hundreds of Sharry Baby each year and there is nothing unusual in the photos you posted.

Sharry Baby have generic characteristics that make them susceptible to fungal spots and poor leaves. Fortunately this does not hurt the plant but they can get to be ratty looking leaves. The flowers make up for it.
