I walked by a shopping cart at WalMart full of these, dead and dying. I asked the clerk what was going to happen to them. "Trash" was what I was told, so I asked how much. I got them for a .25. I brought them home, separated, and re potted them. The roots were Very dried out. I soaked from the bottom up, and took off all the brown/yellowish leaves that didnt fall off during the handling.
That was 3 weeks ago, and I have only bottom soaked them once since re potting them. The tip of a few of the leaves are still drying out, but they all still "look" okay.
I have 9 pots that look like these.

So far so good.
but..
Is there anything else I can do to "help" these along? I have them in the house. I forgot to grab the care tags that were in the basket too.
