Questions about my new cymbidium. (black spots and potting mix)
Hello everyone, and thanks in advance for your generous help.
I was recently forced to purchase this cymbidium (forced by the great deal I got due to supermarket clerk apathy), but I've only grown phalaenopsis orchids before, so I'm kinda out of my element here.
I noticed after I got home that a good portion of the leaves have these small black spots on the underside (see attachment). The picture is of the worst one I found. The spots are only on the undersides of the leaves and aren't even detectable from the top. Some of them have very few spots, about a third have none at all, and then there are a couple like the one pictured. Is this a disease? I'm sure it isn't normal, and I'm curious if I should keep it away from my phalaenopsis orchids until I have it pinned down.
Also, and forgive me for not making another post in a more appropriate section, I was wondering what you guys thought of the potting mix it's in (other attachment). I think it looks terrible, and I'm a bit concerned it may just have fertilizer or something thrown on top of it. I'm not familiar with the medium cymbidiums would be best grown in, and was hoping for some thoughts on this also. And on a related note I was wondering, if I were to repot, are these all separate plants? Should I keep them together or repot them all individually?
Again, thanks for all the advice.
