I noticed one of the phals that my (very generous) boss gave me had a large yellow spot on the leaf (it only had one when I got it)
Today I pulled it out of the medium which was clay beads and spag packed around the root ball itself and there is a big black section on the part that joins the roots to the leaves.
PLEASE tell me that my poor phal can pull through.
I know that I'm supposed to pour peroxide over it, which I did, and heard a hissing noise when I listened. I put it in fresh clay beads once Id taken off any roots that looked dodgey and didnt water it as id rinsed the roots after cutting them.
any other advice? did I do the right thing? I'm worried, This was my second fave phal.
