Is it okay to cut off Monstera roots?

Yes. You can cut the rope of root reaching out of the side of your monstera's pot, and you can cut the tangle of roots under the soil, and the plant will be fine in both cases. A clean blade, no more than about a third taken in a single session, and within a few days the leaves look the way they did before you started. The thing worth knowing about that rope coming out of the pot, though, is that it is not really a houseplant feature at all. Monsteras are tree-climbers, and that root is the apparatus they evolved to climb with, which means cutting it does not hurt the plant but it does change how it grows from that point on.

How Do I Actually Cut a Monstera Root Safely?

Wipe the blade of your scissors or pruners with rubbing alcohol, or run the tip through a flame for a few seconds and let it cool. The cut you are about to make is an open wound on the plant, and a dirty blade is the one realistic way to introduce an infection that the plant otherwise has no trouble shrugging off.

For an aerial root, find the spot where the root joins the stem and snip it cleanly, leaving a short stub of about a quarter inch rather than sawing flush into the stem. A flush cut nicks the stem tissue itself, and that is where rot can get a foothold. A small stub dries out and seals over on its own.

For underground roots, the only time you really need to think about this is during a repot, when the plant is already out of the pot and you can see what you are working with. Tease the root ball apart enough to see the roots, then cut back the longest and most tangled ones with the same clean blade. Healthy monstera roots are firm and tan or pale brown, sometimes with greenish tips. Aim for those, leave them, and trim only the obvious excess.

The one rule that matters across both cases is volume. Never take more than about a third of the plant's total root mass in one sitting, whether you are pruning aerials, trimming underground roots at a repot, or doing both at once. The roots feed the canopy; cut too many and the leaves above start to yellow and drop because the remaining roots cannot keep up with them. A third is the working ceiling almost everyone who prunes houseplant roots converges on, and it is conservative enough that a healthy monstera will not even register the loss.

A quick safety checklist before you start:

• Clean the blade with rubbing alcohol or a quick pass through a flame
• Use the sharpest scissors or pruners you have, so the cut is clean rather than crushed
• Leave a short stub at the stem, do not cut flush
• Remove no more than about a third of the roots in one session
• Watch the leaves over the next week for yellowing or wilting

What If the Roots Are Rotting, Not Just Long?

This is the one case where cutting roots stops being optional and becomes the fix. Root rot is a bacterial and fungal infection that spreads through the root system from a single damaged or waterlogged starting point, and the only way to stop it is to physically remove the affected tissue before it reaches the stem.

You will know rot when you see it. A healthy monstera root, underground, is firm to the touch and tan, pale brown, or sometimes a little greenish at the tip. A rotted root is dark brown to black, soft, often slimy, and pulls apart between your fingers when you tug on it. There is usually a sour, sulfurous smell rising off the root ball as soon as you lift the plant out of the pot. Above the soil, aerial roots that have gone from plump and silvery-green to shriveled and blackened, with the surface peeling off, are the same problem expressing itself on the visible roots.

When you are cutting rotted roots, the one-third rule goes out the window. Cut back to firm, white-or-tan tissue everywhere you find rot, even if that means losing half the root mass or more. Leaving an inch of rotted tissue behind is worse than losing extra healthy root, because the rot will keep advancing from whatever you left.

One thing worth separating out: an aerial root that has gone crispy and brown on its own, while the rest of the plant looks fine, is almost always just a humidity issue. The root tip dries out faster than the rest because it is the part most exposed to the air. That is cosmetic, not rot, and it does not need surgery. You can snip the dry portion off if it bothers you, but the plant is not in trouble.

Once the rotted tissue is off the plant, the rest of the work is repotting into fresh, fast-draining medium and adjusting your watering so the new roots never sit in saturated soil again. Most monsteras come back from a serious rot event if you catch it before the infection reaches the stem itself.

Why Do Monsteras Grow Aerial Roots in the First Place?

In its native range, monstera deliciosa is not the tabletop plant you have. It is a tree-climber. Specifically, it is a hemiepiphyte, which means it starts life as a seedling on the rainforest floor and then spends the rest of its life climbing up the trunk of a tree, sometimes reaching twenty meters into the canopy. The aerial roots are the apparatus that makes that climb possible.

There are two jobs the roots are doing up there. Anchoring roots grip directly into the bark of the host tree, gluing the climbing stem to the trunk so the plant does not peel away under its own weight. Feeder roots, which are usually the longer, more flexible ones, absorb humidity from the air and intercept rainwater running down the trunk during a storm. Together they let the plant skip the slow, expensive work of sending a single trunk up through twenty meters of competition and instead use the tree as scaffolding.

When that same plant ends up in a ceramic pot in a living room, none of that biology switches off. The plant still grows aerial roots, because that is what the genus does. They reach out into the air looking for something to grip, and finding nothing, they dangle. The rope coming out of the side of your pot is not a defect or an oddity. It is the plant trying to climb in a room that does not have a tree.

Did you know? In the rainforests of Central America, a single monstera deliciosa can climb more than twenty meters up a host tree, with aerial roots reaching back down to the forest floor from high in the canopy and re-rooting like guy-wires. The plant in the corner of your living room is the same species, doing the same thing on a much smaller scale.

What Else Can I Do with Aerial Roots Besides Cut Them?

The easiest alternative is redirection. Take the aerial root, bend it gently down toward the pot, and tuck the end into the soil. The root will keep growing once it is buried, and within a few weeks it will start behaving like an underground root, branching out and pulling water from the mix. You get the same end result as cutting, in that the rope is no longer hanging in the air, but the plant now has more root mass feeding the canopy. Top-heavy monsteras also lean less when their aerial roots reach the soil, because the buried portion adds a bit of anchor weight low in the pot.

The other option is to give the plant something to climb. A moss pole, a wooden plank, or a cedar slab pressed into the back of the pot will give the aerial roots a surface to grip. Once they latch on, the plant starts behaving the way it would in a forest, and the visible payoff is real: leaves get larger, the fenestrations (the holes and splits that make monstera leaves look like monstera leaves) develop earlier and more dramatically, and the whole plant grows upward instead of sideways. The roots are doing exactly what they were built to do, and the plant rewards you for letting them.

Redirecting into soil and giving the plant a moss pole are the two main ways to handle a monstera's aerial roots without cutting them off, and you can combine them on the same plant if it has roots heading in different directions.

Cutting is still a perfectly legitimate choice if you do not love the look. The plant will not punish you for it. But the aerial root is not a houseplant defect to be tidied up. It is a tree-climber working with the apparatus it has, in a room that does not happen to have a tree. Once you see them that way, the choice between cutting, redirecting, and leaving them stops feeling like a verdict on whether you are doing right by the plant, and starts feeling like what it actually is: a decision about what you want the plant to look like.
