if they're not growing and show a yellow sign, then the cave blossoms need darkness and normally a size 2 pot, forest sprigs don't care about light but need a size 2/3 pot, ancient ferns need to be out of the darkness and need a size 2/3 pot, and curling vines are the same as forest sprigs. i've had the same no water sign happen to me, but after i watered them once it came back. if it's not any of these things that work, then i suggest asking the developer for help
