I was given this poor thing by a close friend & want to bring it back to life...
Can somebody please advise me what it is... is it a cactus or succulent..?
As you can see she was in a pretty bad way when I got her (2/3 weeks ago) but she now seems stronger and doesn\'t have so many flaky bits on her. I think she was parched, and needed a really good drink. I understand that she needs a good drink but what else can I do to help her..?
Will she flower or grow extra limbs..?
I have no experience at all :(
Thank you so much for all your advice in advance ladies & gentlemen.
Below photo is how she was when I got her..!!
