I got this cactus from my Dad and have had it almost a year. I'm wondering if it's still alive. Sure the top is green, but the bottom seems so dead. Can I cut it in half and replant it? Should I do anything to help it out? Thanks.
Yeah, I'd cut the top, removing it from the bad growth that looks as though it's gone to a higher place. Wait to water until the healthy portion has re-rooted.
