My 4" pot lacunosa 'plant' (which I suspect was several pretty recent cuttings potted together before they had strong roots) spent its first week drooping quite a bit and also dropping more than a dozen leaves which turned yellow first.
It seemed quite stressed from its journey to me, during which it totally dried. I did not repot it, simply kept the soil moist.
Now is day ten, and over the past 3 days leaves stopped yellowing and dropping, and all the stems and remaining green leaves are perking up. Whew!
Definitely looking MUCH better today and I'm confident it'll do well now. 😺
