I gave up on Stubby. He stopped growing after being potted and never picked back up. The growing tip on the roots kept shrinking so I pulled him out of the pot and the base of the new roots was shriveled and blackened. They didnt adjust to the medium.
I was going to chuck him in the garbage but I changed my mind and just buried him with one of my other phals. I dont have to take care of him anymore, see? That's him on the bottom. I will take care of my other phal, which is happy and growing, and Stubby can continue to die as slowly as he likes :-) It works.
That is an interesting resolution. I grow seedlings in compots as these tiny plants seem to grow better with company. So why wouldn't that work for ailing, older plants? Good idea!
I would be afraid that i may be transferring bad to the other plant. Believe me i hope it works. I have a little phal in icu with same problem. I put a little rootone on the remaining root.
