Nip off the dying end and spray with 1 part rubing acholo/2 parts water, just a lite spray. Or paint brush the areas
with mold. To wet?? Do you have a fan for air circulation? Strip off the leaves!!! You just want the stalk at this point, the roots will come back. Or you can send to me what is left of the plant and I'll try to root for you. Glad to see you are still trying to root, you will get the hang of it if you keep trying.
