Hello all - I've rescued what I think are three houseplants from near where I live and am wondering whether it is possible to save them? I'll try to attach images (this is my first time posting) - there was a fourth, what looked to be another type of cactus, but unfortunately that one I think has already died. All three are extremely sodden and feel very heavy in their pots which I'm assuming is coming from the rain we've been having recently. I'm not sure what plants they are or how long they've been outside for.
I live in a flat but have my own entrance and so I have a little space there if they are best off outside. All my windows face the same direction (south, with one window facing east). Also for reference, I live in the south-west of the UK which is very cold and wet at the moment!
Are they beyond hope, or do they have a chance?
