darks spots on my cymbidium and shriveled bulb

[jamesgang]

I'd like to hear from someone about the black spot too! I have a zygo orchid that has getting worse and I have been treating with Physan 20 (1 t to a gal ) Hope to see some improvement how? black turns to brown is good? what is a sign of healing from black spots ? JD

Generally, I really monitor any dark spots. If they seem to be growing, I cut that part off. If you can get rid of the majority of the infection, then the fungicide/bactericide is just preventative.

That said, Cymbidiums are sensitive to water on the leaves, and can develop dark spots. That's ok. It's ugly, but not life threatening.
