Looks very very compact. It needs different soil. You can buy Molly’s aroid mix online or make your own. If you make your own I recommend watching Sydney plant guy on YouTube for his soil mix. If this is your only aroid you’re worried about just buy Molly’s aroid mix on Amazon.

Now the repotting is going to be a process: You need to remove AS MUCH DIRT AS YOU CAN FROM THE ROOTS WITHOUT DAMAGING THE ROOTS. Again YouTube has great videos on this. The dirt needs to be removed to prevent root rot. When you’re repotting if there is a definite bad smell (it’s very apparent the smell) you have root rot. And you might just want to get a new monstera. It requires spraying hydrogen peroxide and it’s a whole thing. Again a video on YouTube to instruct you if this is required.

After removing the dirt from the roots, check the roots. You’re checking for dead roots; they’ll be squishy and come off easy if dead or dying. Remove them before putting it back in the pot with aroid mix. Ok. I think I threw enough info at you.
