The first yellow leaf always lands the same way. You walk past the window with your coffee, half awake, and something is off. One leaf, the big one you were proud of, has gone the color of weak tea at the edges. And a little voice says: you did this. You finally got a plant, and you are killing it.
Take a breath. You are not killing it. A yellow leaf on a monstera is not a verdict. It is information, and once you learn to read it, this moment stops being scary and starts being the whole point of keeping a plant: paying attention to a living thing, noticing what it needs, and responding. That is the quiet skill monstera owners actually develop. The big leaves are just the reward.
The short answer
Monstera leaves most often turn yellow from overwatering, followed by underwatering, too little light, natural aging of the oldest leaves, or stress after a move or repot. Check the soil first. Soggy soil means back off the watering can. Bone dry soil means the plant ran out. One old leaf yellowing at the bottom of the plant, while everything else looks strong, is usually just age.
Why do monstera leaves turn yellow?
Almost every yellow monstera leaf traces back to one of five causes, and they leave different fingerprints.
1. Overwatering (the most common one)
Monsteras climb trees in the wild. Their roots are built for chunky, airy soil that drains fast, not for sitting in a wet pot. When soil stays soggy, roots suffocate, and the plant starts pulling resources back from its leaves. The fingerprint: several leaves yellowing at once, often with a soft, almost translucent look, soil that stays damp for a week or more, and sometimes a musty smell near the base.
2. Underwatering
The opposite problem leaves a drier signature: leaves that yellow and crisp at the edges, curl slightly, and droop, with soil pulling away from the sides of the pot. If you touch the soil two knuckles deep and feel dust, this is your answer.
3. Not enough light
A monstera in a dim corner cannot make enough energy to support all its leaves, so it retires the oldest ones. The fingerprint: slow, steady yellowing of lower leaves, small new leaves with few or no splits, and long stretched stems reaching toward the window.
4. Natural aging
Every leaf has a lifespan. If one of the lowest, oldest leaves yellows while the rest of the plant is pushing new growth, that is not a problem. That is a plant doing exactly what plants do: investing in what is next.
5. Stress and transition
A move to a new home, a repot, a cold draft from a winter window, or a heat vent blowing directly on the plant can all trigger a yellow leaf or two. Plants dislike sudden change. Give a recently moved monstera a few weeks of consistent care before you diagnose anything else.
How to figure out which cause is yours
Do not guess from the leaf alone. Read the whole plant, the way you would check on a friend rather than diagnose them from one text message.
Start with the soil. Push a finger two inches down. Wet and heavy several days after watering points to overwatering or poor drainage. Dry and dusty points to thirst. Then look at where the yellow is. Bottom leaves only, one at a time, suggests age or light. Yellow spreading across many leaves at once suggests water trouble at the roots. Finally, check the light. Your monstera wants bright, indirect light: close to a window, but not baking in harsh afternoon sun. If you can comfortably read a book by natural light where it sits, you are in the right zone.
How do I fix yellow leaves on a monstera?
Once you know the cause, the fix is refreshingly simple.
If the soil is soggy, stop watering and let the top two inches dry out completely before you water again. Make sure the pot drains, and never let the plant sit in a saucer of standing water. If the soil stays wet for more than a week, slide the plant gently out of its pot and look at the roots. Healthy roots are firm and white or tan. Brown, mushy, sour smelling roots are rotting: trim them off with clean scissors and repot into fresh, chunky soil.
If the soil is bone dry, water slowly and thoroughly until it runs from the drainage holes, then set a rhythm. For most homes that means checking weekly and watering when the top two inches are dry. The rhythm matters more than the calendar. A watering routine is one of those small rituals that quietly anchors a week, which is half the reason to keep a plant at all.
If light is the issue, move your monstera closer to a window. You will be surprised how quickly it thanks you: new leaves come in larger, and the deep green returns.
Should I cut yellow leaves off my monstera?
Yes, once a leaf is mostly yellow, it will not recover, and the plant is already withdrawing from it. Snip it at the base of the stem with clean scissors. Removing it tidies the plant and lets it put energy into new growth. Think of it less as losing a leaf and more as making room.
Can a yellow leaf turn green again?
Almost never, and that is okay. The goal is not to save individual leaves. The goal is a plant that keeps making new ones. Fix the cause, and the next leaf that unfurls is your proof that you listened correctly. There are few small satisfactions like it.
What a yellow leaf teaches you
Here is the reframe worth keeping: nobody who owns a thriving monstera got there without a few yellow leaves. Each one taught them something about their light, their soil, their habits. Caring for a plant is not about never making mistakes. It is about noticing, adjusting, and showing up again next week. The plant grows, and quietly, so does the person tending it.
Ready to grow one of your own?
If you are reading this before buying your first monstera, take this as encouragement: they are far more forgiving than their dramatic reputation suggests, and few plants give you more visible progress to enjoy.
The classic Split-Leaf Monstera Deliciosa is the one you picture when you close your eyes: big, glossy, fenestrated leaves that turn any room into somewhere you want to linger. If you love a more delicate, trailing look, the Swiss Cheese Plant Monstera Adansonii grows fast and drapes beautifully from a shelf. And for collectors ready for something rarer, the Variegated Monstera Adansonii splashes every leaf with cream, no two alike.
