Went to the store again. It was still there so...
Dead leaves removed from the pot and from the plant's underside, so to speak. Will have to be repotted as it is difficult to balance it at the moment and I presume the soil it is in might not be the best for it.
The bad news is that a small part of the plant broke off when I was carrying it.
My question would be, could that part be planted along with the main plant?
If so, what should be done for it to have any chance of survival? How long can it lie on a shelf (indoors) like this?
