Thanks everyone! I'll try to save her for sure. Already cut the dead roots and repotted. She bloomed right after that!
I know that my mom sadly drowned her, gave her a little water every time she walked past. I have gotten into the "plant lover" state half a year ago so I did not even realize it early enough to give the plant proper care.
I was lucky with these other two
They are thriving!
Ardesia's pictures gave me a little hope though
Thank you!
