A neighbor I was close with recently died and their family asked if I would take the plants, of course I said yes, but 2 of them I know very little about.
I think they might be the same plant at different life stages? Can anyone help me ID these?
What I’m seeing online, the leaves should be standing straight up. Any tips on how I should care for these floppy ones? Should I prune them, repot them, or anything?
It could be a variety of things, it's hard to know exactly from just the pictures, but some reasons why they could be drooping is them not getting enough light and/or too much water. I always repot new plants that I get especially if they don't look healthy just to check for any rot or fungus and I like to put them in my own dirt too. You can remove the dead leaves if you'd like, but I'd leave the green ones be.
Also don't water them when you repot since I'm guessing that they did get too much water, unless the dirt is very dry then they were probably underwatered in which case water them.
They need very little water. Especially during winter. Seconding everything on the other comment too. I would repot them with fresh, well draining soil and if you see anything squishy and brown, cut it off. If you have to cut on the roots, leave it out for a day before putting it back in soil to let the cut callus over. Snake plants are tough, they won't mind.
Depending on your local climate, they would probably make better indoor plants. They'll tolerate low light areas that other plants won't.
