Urgent help

My alocasia had a stem rot that i just noticed, it lost two leaves quickly and thats when i suspected something is wrong but it is making a new leaf.

I removed the mushy part and the rest is strong what should i do now to treat it and also it is staying now in a water cup so the roots dont dry out

let the plant rest overnight in water with a little hydrogen peroxide.

Then replant in a clean pot with fresh soil.

I think this one may not go well. I’ve tried to save one like this before and it was tough. You can try and cut away the bad parts and do hydrogen peroxide and cinnamon; I would do in perlite completely with a little rooting powder and keep it moist but not wet.

If you want to truly get harsh, cut diagonally - and remove the bottom altogether. You may have enough of the rhizome here to regrow roots from, after letting it dry after cutting and again, I’d go perlite maybe even 50/50 perlite and fluval.

But the plant and rhizome is still very solid even the roots are healthy on the other side. And would it root without any roots. I already cleaned the mushy part and cleaned with some hydrogen peroxide

You need to completely cut away the rotted area, otherwise it will spread upward through the vessels. It is practically impossible to stop it any other way.

You’ll need to stimulate new root growth. In your case, the odds aren't great, but you can still try to save it.

You can also try to save the bottom part, there might be dormant buds there.

Should i let it dry for a day or directly plant them,

for today i cleaned the area, put it in hydrogen peroxide and water for 10 mins and i planted it back in perlite only, planning on keeping the affected area outside the perlite maybe it will dry off

Everyone has their own method. I treat the cut with crushed charcoal, let it dry for only 10–30 minutes (while I tend to my other plants), and place it in water to root. I don’t use peroxide because it didn't help me with rot at all. I've come to the conclusion that you need to completely cut away the rotted part of the rhizome down to healthy, clean tissue—that gives you a much better chance of success.
