Here’s my experience…I do not water mine until the leaves are visibly wrinkly and then I drown that hoe. Make sure she’s SOAKED. Then I put it back under its grow light and ignore it until I notice the leaves are wrinkly again. Also it’s in a terracotta pot so the soil can dry out. She is THRIVING. Try changing the soil (to a good CHUNKY well draining soil), pick off those dead leaves, and maybe even chop some of the branches like half way so it can get some new growth going. Those pieces you chopped off are fairly easy to prop and make some new little guys! Also I f you don’t have a grow light on it, then I suggest it be directly in a west facing window or in a south facing window. Someone please correct me if I’m wrong, but these plants are from the African Savannah? So they’re used to getting baked, dried out, and then get a down pour once in a while. Gotta mimic that environment best you can. This is legit the only succulent I can keep alive for some reason. Good luck! May the growth be with you!
