Hi Kara, and a great big
to ATP. So glad you found your way here.
I see we have 4 members that have Echeveria Chroma. I think one of them could give you the help you need. I will see if Trish or Dave can move this thread to the Cactus and Tender Succulent Forum.
Seems like you are doing some of the things your lovely plant needs to help heal.
Cinta is correct, your plant is not a Sempervivum but probably Echeveria Chroma.
Lets see if we can get
@Ecograndma,
@MagerRooRHammer,
@webesemps and
@GigiPlumeria to help you out with this plant.
I look forward to seeing the advice that will come from some of our other members that know this plant. Another learning experience for many of us.
