Help! Newbie with severely damaged cactus
I just acquired this 5 foot cactus and it's in awful shape. Apparently it was neglected in a basement without light, water, or heat for a few months. I'm new to cacti but I'm desperate to save this plant!
Numerous arms have fallen over at the joints, some large stems are getting soft and have spots of mold, the base still feels hard but has spots of mold here and there and isn't a healthy color. The tips are the only thing that seem healthy.
Can I save this? What do I do?
