Can you fix Monstera root rot?

Published 5 June 2026

Yes, root rot is usually fixable, and a monstera (Monstera deliciosa) can come back even when it has lost every single root. That sounds backwards, because the roots are the part you're staring at in horror. But survival comes down to the stem and one healthy node, not the roots at all, which means a rootless plant is often saveable while one with a soft, collapsing stem usually isn't. So before you write yours off, stop looking at the mush in your hands and go feel the stem.

How Do I Know If It's Too Far Gone?

Start with the stem, not the roots. Pinch it near the base, just above the soil line. Healthy stem tissue is firm and pushes back. If it feels soft, gives under your fingers, or has gone brown and mushy up into the growth point at the top, the rot has reached the part of the plant that can't be replaced, and the plant is usually finished. If the stem is firm, you almost certainly have a saveable plant, no matter what the roots look like.

The roots come next, and they're far more forgiving. Pull the plant out and feel them. Firm white or tan roots are alive. Brown, slimy roots that smell sour and slide apart when you tug them are dead. You can lose nearly all of them and still recover the plant, so don't let a fistful of black mush convince you it's over.

Then find a node. A node is the slightly swollen band on the stem where a leaf and roots emerge, and it's the single most important thing to locate. As long as one node is firm and shows white or green tissue when you scratch the surface, the plant has a place to regrow from. Squeeze it the same way you squeezed the stem: firm means living, soft means gone.

What Do I Actually Do to Fix It?

Get the plant out of the wet soil first. Tip it out of the pot and rinse every bit of soil off the roots under the tap so you can actually see what you're working with. Rotten roots hide inside a clump of soggy soil, and you can't trim what you can't see.

Then cut. With clean shears, trim every mushy, brown, slimy root back to firm white tissue. Don't be gentle about it. A root that's even partly soft will keep rotting, so cut into healthy tissue rather than leaving a borderline section. If that means removing almost the entire root mass, remove it. The plant can rebuild roots far more easily than it can fight an active infection.

Hydrogen peroxide and fungicides come up a lot at this point, so it helps to know what they actually do. A diluted hydrogen peroxide rinse can clean the cut surfaces and knock back surface organisms for a few minutes, but it isn't a cure, and soaking the roots in it won't undo rot that's already happened. Fungicides have the same limit. The actual cure is mechanical: you remove the rotten tissue, and you fix the conditions that drowned the roots. Chemistry can't out-treat a pot that stays waterlogged.

Let the trimmed cuts air-dry for a few hours so the wounds can callus over slightly before they go back into a moist medium. Then repot, and size the pot to the roots you have left, not the roots you started with. A small root system swimming in a big pot of soil sits surrounded by water it can't drink, which is exactly the situation that caused the rot. Use a chunky, fast-draining aroid mix and a pot with drainage holes.

  • Tip the plant out and rinse all the soil off the roots
  • Trim every mushy root back to firm white tissue with clean shears
  • Decide whether peroxide or fungicide is worth it (a rinse at most, never the cure)
  • Let the cut surfaces air-dry for a few hours
  • Repot into chunky, fast-draining aroid mix in a pot with drainage holes
  • Size the new pot to the reduced roots, then wait

Expect the plant to look bare and sad for several weeks afterward. A monstera that's just lost most of its roots can't support all its leaves, so some yellowing or drooping is normal while it rebuilds underground. That isn't the rescue failing. It's the plant rationing what it has.

What If It's Lost All Its Roots?

A monstera with no roots left is still a saveable plant, and this is the case that causes the most panic. The reason it works comes down to where a monstera keeps its ability to grow: in the node. Each node carries the dormant tissue for both a new shoot and new roots, so a stem with one good node can rebuild an entire root system from scratch. The buried roots you lost were never the irreplaceable part.

Cut the stem back until you're left with at least one firm, healthy node, removing everything mushy below it. If that node already has an aerial root attached, even a stubby one, so much the better, because that's a head start on the new root system. The plant produces these woody roots along its stem in the first place to grip and climb, and they convert to water-drinking roots readily once they're in a moist medium. Those same aerial roots a monstera sends out along its stem are what make this kind of recovery possible, so the stubby ones you might normally tuck away or trim off are suddenly the most valuable thing on the plant.

Root the node in either water or damp sphagnum moss. Sit the node and any aerial root in the medium, keep it warm and in bright indirect light, and change the water every few days if you're using water. New white roots usually appear within two to four weeks. Once they're a couple of inches long, you can pot the plant up into normal aroid mix and you've effectively started the plant over from the one part that was never going to rot.

Why Did This Happen in the First Place?

Root rot isn't really caused by water. It's caused by what waterlogged soil does to air. Healthy soil has tiny pockets of air between its particles, and roots pull oxygen straight out of those pockets to stay alive. When soil stays soaked, water fills those pockets and drives the air out. The roots suffocate, die, and then rot organisms move in to colonize the dead tissue. The rot is the second event. The drowning comes first.

This hits monsteras harder than most houseplants because of how their roots evolved. A monstera is a climbing aroid that grows up the trunks of trees, with its roots clinging to bark out in the open air rather than buried in ground. Those roots are built to drink during rain and then dry out and breathe between downpours. Pack them into dense, constantly damp potting soil and you've put them somewhere their entire biology never expected, with no air and no chance to dry. They suffocate fast.

Did you know? In the rainforest, a monstera's roots grip the outside of tree trunks, fully exposed to open air and drying out between rains. A pot of dense, always-damp soil is about as far from that as you can get, which is exactly why it's such a reliable way to kill the roots.

How Do I Keep It From Coming Back?

The fix only holds if you change what caused it, and the main culprit is watering by the calendar. A monstera doesn't drink on a schedule, so don't water on one. Check the soil instead: push a finger in, and only water once the top few centimeters have actually dried out. A plant in low light or cool weather can stay wet for weeks, and watering it again on day seven because the calendar says so is how roots drown.

The pot and the mix do half the work for you. A chunky aroid mix full of bark and perlite drains fast and holds the air pockets that dense soil loses, which is the whole reason it suits roots that need air to survive. Always use a pot with drainage holes so excess water has somewhere to go, and empty the saucer after watering rather than letting the plant stand in the runoff. A pot that can't drain turns every watering into the start of the next problem.

Once you've been through a rescue, you'll start catching trouble earlier, and the warning signs of a monstera that's getting too much water show up well before the roots are gone. That early recognition is what makes the difference, because the roots a beginner panics over are the most replaceable part of the plant. What actually matters is the firm stem and a single living node, the same climbing-aroid biology that lets a monstera throw new roots wherever it grabs hold. Once you see that, root rot stops being a death sentence and becomes a setback the plant is built to survive.
