Sorry 😞, my friend.
Time for eulogy, and proper burial.
Don't give up though 👍
I killed many, before I got it right. Especially those fat kind.
One ! Just one ! Overwatering ! Pow ! Root Rot city. 😭😭😭
You want drain holes in pot, and no rocks/gravel on top, fast draining soil, so much to go into.
check on care of particular variety/s .
Get back hear ! Same post.
When you get new one, buy a tad bit bigger pot, for it. also, equal size bags of cati soil mix, and perlite.
I'll guide you.
Ttfn friend 😀
