I know they are good for other plants (non-orchids) since they loosen the soil. I just wasn't sure about orchids. I've read about some people using worm tea for their orchids (not sure what it is, but I'm guessing something like fertilizer?), so I started wondering if worms were beneficial for orchids in some way. Then again, I don't know if they were the culprits for the roots being in pieces. It couldn't have been from shipping because the pieces were mixed thoroughly throughout the medium.
I wasn't sure if the medium was breaking down. It looks like small uniform sized bark chips. However, it's really dark and leaves dirt like residue when I was going through the pot (before I found the worms).
I did call the place where I got it from last night. I told him about the roots and sent him photos. He was very nice about everything and said to keep him updated on its progress and if it didn't survive, he would be able to offer me a substitution or refund (as he didn't have anymore den victoria-reginae).
I am very excited about my new cymbidium! I just watered it with it sitting in a wide bucket. I wasn't sure how to water it exactly, since I don't own a hose and couldn't get to the edges. I'm used to watering where I avoid a crown (as with phals) but saw no other option other than to pour water through a water bottle over the top. It seems pretty happy! Thank you for your advice!
