Extensive brown spots on cactus (south florida)
Hey yall, hoping i can get some insight on how to care for my cactus. I absolutely love this cactus and have had it for about 10-11 years. She survived outside with a massive hurricane and i just completely love her.
I've noticed these extensive and large brown spots on her and was concerned if i needed to change any of her care and recently stumbled on this subreddit. We're in south florida and shes always outside. The water she gets is only when it rains; i never water her because i figured cactus wouldnt need any more. She's in the sun during most of the day. The brown spots are hard and not mushy at all.
Looking at other posts it seems like this is corking and is a natural process given her age. Does this mean shes close to the end of her lifespan? i feel like there should be something i can do for her to grow green?
In addition, shes getting pretty tall and i may have trim her if thats at all possible? how could i go about doing that?
Thanks yall!
