I was given three small bunny ear cacti from someone a couple days ago. Before they gave them to me they hadnt been in soil for a few days and them postage took another two days. They’ve been potted up now for a couple days and they seem definitively like theyre dying! I gave them some water when they were first potted for root growth but not a lot and theyre on my west facing window all day (although it is winter so not super sunny) is there anything i can do to save them? Or are they a lost cause?
