Basal keikies but no roots
My Phal has two basal keikis, but the roots have all gone away except one very sick looking one. What do I do to encourage roots and still save the keilis. I have dipped the base in a rooting hormone paste, now do I put it under the grow light or do I put it in the dark? Do I keep it warm or cool? I have heard to soak the whole thing in fertilizer water for a half hour. It may not be worth saving, but if I don't try I will never learn.
