Why Your Monstera Leaves Are Turning Yellow (Quick Answer)
A monstera turns yellow most often from overwatering — its thick roots rot fast in soggy soil, and the oldest, lowest leaves yellow and drop first. Check the soil before anything else: if it's wet and heavy days after watering, stop watering and let it dry out fully. If just one or two of the lowest leaves are yellowing while the newest growth looks great, that's normal aging, not a problem you need to fix.
Monstera (Monstera deliciosa) is a forgiving plant, so yellow leaves usually mean it's getting too much care, not too little. University of Maryland Extension flags overwatering as the most common cause of houseplant decline — excess water pushes oxygen out of the soil, damages the fine roots, and produces wilting and yellowing that owners keep misreading as thirst, so they water more and make it worse. Below, every cause is ranked by how often it's actually the answer, each with the one tell that separates it from the rest. Want a second opinion on a photo? Our plant diagnosis tool narrows it down in a few taps, and our yellow leaves guide covers the full differential across every houseplant.
Monstera Yellow Leaf Diagnostic Chart
Match what you're seeing to the row below, then jump to that section. Monsteras are readable — where the yellowing starts and what the stem base feels like usually points straight at the cause.
| What you see | Most likely cause | First move |
|---|---|---|
| Yellow + soft, mushy stem base, wet soil | Overwatering / root rot | Stop watering; check the roots |
| Yellow + dry, crispy edges, bone-dry soil | Underwatering | Soak thoroughly, then water sooner |
| 1–2 lowest leaves only, slow, rest thriving | Natural aging | Nothing — snip them off |
| Bleached yellow patches on the window side | Direct-sun scorch | Pull back out of direct sun |
| Uniform pale yellow, small new leaves | Nutrient deficiency | Dilute balanced fertilizer |
| Yellow stippling + fine webbing or specks | Pests (mites, thrips, scale) | Inspect leaf undersides |
| Sudden yellowing near a draft or vent | Cold stress | Move to a stable 65–85°F spot |
Cause #1: Overwatering (Nearly Always the Answer)
Start here. Monstera's fleshy aroid roots need air as much as water, and in dense, waterlogged mix they suffocate and rot — at which point the plant can't take up water even though it's sitting in it, so it drops its oldest leaves. University of Maryland Extension notes that root rot can paradoxically cause wilting and yellowing even when the soil is wet, which is exactly why the instinct to water a sad-looking monstera so often backfires.
The monstera-specific tell is the stem base and the petioles (the stalks connecting each leaf to the main stem). Pinch the vine where it meets the soil. On an overwatered monstera it feels soft, brown, or slightly slimy, and the petioles of yellowing leaves go limp and translucent at the base. Wet soil plus a mushy base plus yellowing lower leaves is overwatering until proven otherwise — even if you don't think you water much. A pot with no drainage hole, a decorative cachepot that traps runoff, or a saucer you forget to empty will overwater the plant for you.
The fix depends on how far it's gone. If the roots are mostly firm and pale, just stop watering, empty the saucer, and let the mix dry until the top 2–3 inches are dry to the knuckle. If the stem base is mush and the pot smells sour, you're into root rot: unpot, rinse the roots, cut away everything brown and soft with sterilized scissors, and repot into fresh, chunky aroid mix (potting soil cut with orchid bark and perlite). Our full root rot rescue guide walks every step, including the save-vs-restart call. Monstera roots easily from a cutting — if the root system is gone, snip a healthy section of vine with a node and an aerial root and start over in water or sphagnum.
Cause #2: Natural Aging (Leave It Alone)
Not every yellow leaf is a distress signal. A growing monstera constantly retires its oldest leaves, pulling their nutrients back into the plant to fund new fenestrated growth up top. One lower leaf turning uniformly yellow every few weeks, while the rest of the plant looks healthy and new leaves keep unfurling, is completely normal.
How to know it's just age: it's the oldest, lowest leaf; it yellows evenly rather than in blotches or spots; and it's one leaf at a time, not a wave of them. Snip it at the base of the petiole and move on. Start troubleshooting only when three or more leaves yellow at once, when new leaves are affected, or when yellowing comes with mushy stems or spotting — that points to water, light, or pests instead.
Cause #3: Too Much Direct Sun (or, Rarely, Too Little Light)
Monstera evolved under a rainforest canopy, so harsh direct sun scorches it. If the yellowing shows up as bleached, washed-out patches on the leaves facing a hot south or west window — often with crispy tan centers — that's sun scorch. Pull the plant a few feet back from the glass or filter the light with a sheer curtain. Scorched patches won't turn green again, but new growth will come in normal.
The opposite problem is milder. In a genuinely dark corner a monstera slows down, stretches toward the light with long gaps between leaves, stops producing fenestrations, and eventually pales as it can't sustain its older foliage. It rarely goes fully yellow from low light alone, but combined with the wet soil a low-light plant holds onto for weeks, it's a common one-two punch. The fix for both extremes is bright indirect light — near a window but out of the direct beam.
The Other Causes (Quick Checks)
Once water, age, and light are ruled out, run through these:
- Underwatering. Less common than overwatering, but real. The tell is dry, crispy yellow edges, soil pulled away from the pot wall, and a pot that feels light when you lift it. Soak it thoroughly until water runs out the bottom, then water a little sooner going forward.
- Nutrient deficiency. A monstera that hasn't been fed in six months or more may yellow uniformly, often with small, pale new leaves — a nitrogen shortage. A dilute balanced liquid fertilizer (something like 10-10-10 or a 3-1-2) once a month in spring and summer fixes it. Don't overfeed; salt buildup causes its own leaf burn.
- Cold stress. Growth stalls below 60°F, and a blast from a drafty window, an exterior door, or an A/C vent can yellow leaves within days. Keep it in a stable 65–85°F spot away from vents.
- Pests. Check the leaf undersides and the crevices where petioles meet the stem. Fine webbing with yellow stippling means spider mites; silvery streaks and tiny black specks on new leaves mean thrips (monstera's unfurling leaves are a thrips magnet); cottony white tufts are mealybugs; and small brown bumps that don't rub off are scale insects. Chronically wet soil also breeds fungus gnats — harmless themselves, but a flashing sign you're overwatering.
Should You Cut Yellow Monstera Leaves — and Can They Turn Green Again?
Once a monstera leaf yellows, it won't turn green again — the chlorophyll has already broken down and doesn't come back. There's no reason to wait on a fully yellow leaf, and leaving it on just costs the plant energy. Cut it at the base of the petiole with clean, sharp scissors, flush to the main stem so you don't leave an ugly stub.
The one exception: if a leaf is only partly yellow and the rest is still firm and green, the plant may still be reabsorbing nutrients from it — you can leave it until it yellows fully. Either way, the dead leaf matters far less than the cause. Fix the underlying problem (nine times out of ten, back off the water) so the next leaf doesn't follow it.
How to Keep a Monstera Green for Good
Get the watering and the pot right and a monstera is genuinely low-drama.
- Water by touch, not by calendar. Let the top 2–3 inches of soil dry out, then water thoroughly until it runs from the drainage hole. That's often every 1–2 weeks in bright light in summer and every 2–4 weeks in winter, but the finger test beats any schedule.
- Use a chunky, fast-draining aroid mix. Standard potting soil packs down and stays wet; cut it with orchid bark and perlite so the thick roots get air.
- Insist on a drainage hole and empty the saucer within 30 minutes of watering. A no-hole cachepot is the single most common hidden cause of monstera rot.
- Give it bright indirect light and a moss pole to climb, which also encourages bigger, more fenestrated leaves.

FAQ
Why is my monstera turning yellow?▼
The most common cause by far is overwatering — soggy soil rots the roots and the oldest, lowest leaves yellow and drop first. Check the soil and the stem base: wet soil plus a soft, mushy base means overwatering, while a firm base with bone-dry soil points to underwatering. One or two yellowing bottom leaves on an otherwise healthy plant is just normal aging.
Should I cut yellow leaves off my monstera?▼
Yes, once a leaf is fully yellow. It won't recover its color and it costs the plant energy, so snip it at the base of the petiole with clean scissors, flush to the stem. If a leaf is only partly yellow, you can leave it until it yellows fully — the plant is still reabsorbing nutrients from it. Most important is fixing the cause, usually by watering less.
Can a yellow monstera leaf turn green again?▼
No. Once a leaf has yellowed, the chlorophyll has broken down and won't return. New growth will be green if you correct the underlying cause, but the individual yellow leaf is done — don't wait on it.
How often should I water a monstera?▼
Let the top 2–3 inches of soil dry out, then water thoroughly until it drains from the bottom. In bright, indirect light that's roughly every 1–2 weeks in summer and every 2–4 weeks in winter, but the finger test always beats a fixed schedule — monsteras far prefer being a little dry to a little too wet.
Is one yellow leaf on my monstera normal?▼
Usually, yes. A growing monstera retires its oldest lower leaves to fund new growth, so one bottom leaf yellowing evenly every few weeks — while the newest leaves look healthy — is completely normal. Worry only when several leaves yellow at once, new leaves are affected, or yellowing comes with mushy stems or spots.
