Seeing yellow leaves on your Monstera adansonii is unsettling, especially when this plant is usually such an easygoing grower. The good news: yellowing almost always points to a watering or light issue you can fix quickly, and your plant can bounce back once the root cause is addressed.
Quick Diagnosis
| What you see | Most likely cause | First fix |
|---|---|---|
| Several lower leaves yellowing, soil feels soggy | Overwatering / root rot | Let soil dry out, check roots |
| One or two older leaves yellowing slowly | Natural leaf aging | No action needed, remove when fully yellow |
| Yellow leaves with crispy brown edges | Underwatering or low humidity | Water deeply, increase humidity |
| Pale yellow leaves, plant stretching toward window | Too much direct light or too little light | Adjust placement, see light needs below |
Cause 1: Overwatering and Root Rot
This is, by far, the most common reason a Monstera adansonii turns yellow. These vining aroids like their soil to dry out somewhat between waterings, and when the roots sit in constantly wet soil, they can't breathe properly and begin to rot. Yellowing usually starts on the lower, older leaves and can spread quickly if ignored.
Check the soil with your finger down to the second knuckle. If it's still damp a week or more after your last watering, you're watering too often. Pull the plant from its pot and inspect the roots — healthy roots are white or light tan and firm, while rotten roots are brown, mushy, and often smell sour. If you find rot, trim away the affected roots with clean scissors and repot into fresh, well-draining mix. Our guide on how to save a houseplant from root rot walks through the full recovery process step by step.
Going forward, only water when the top 1-2 inches of soil are dry, and make sure your pot has drainage holes. For a general watering baseline you can adapt to your home's conditions, see how often to water houseplants.
Cause 2: Underwatering and Low Humidity
On the flip side, a Monstera adansonii that's gone too long without water will also yellow — often paired with crispy, brittle edges rather than mushy, translucent patches. Because this plant is a tropical vine, it also appreciates moderate humidity; in very dry air, leaf edges can yellow and crisp even when watering is adequate.
If the soil has pulled away from the pot's edges or feels bone-dry and light, it's time for a thorough watering. Soak the soil until water runs from the drainage holes, then let the excess drain completely. Avoid a "little sip" approach that only wets the top layer, since this encourages shallow, stressed roots.
A humidity tray, nearby humidifier, or grouping plants together can help if your home runs below 40% humidity, especially in winter with heating running. Consistency matters more than perfection — aim for an even watering rhythm rather than long dry spells followed by drenching.
Cause 3: Too Much or Too Little Light
Monstera adansonii thrives in bright, indirect light. Too little light causes weak, pale, yellowish new growth and leggy stems as the plant stretches toward any light source. Too much direct sun, especially through an unfiltered south- or west-facing window, can bleach leaves to a washed-out yellow with scorched patches.
Move your plant a few feet back from intense direct sun, or add a sheer curtain to diffuse the light. If your plant is in a dim corner, relocate it closer to a bright window or consider a grow light. For a deeper breakdown of light levels and how to measure what "bright indirect light" actually means in your space, check out how much light do houseplants need.
If your lighting is inconsistent and you're unsure whether your plant is getting enough, a simple light meter app or an affordable grow light can take the guesswork out of it entirely.
Supplements natural light so your Monstera adansonii gets consistent, healthy brightness even in darker rooms or winter months.

If watering and light both check out but yellowing persists — particularly uniform yellowing across older leaves, or yellowing between leaf veins on newer growth — your plant may be hungry. Monstera adansonii is a relatively fast grower during spring and summer and can deplete nutrients in its potting mix, especially if it hasn't been repotted or fed in over a year.
Feed with a balanced, diluted liquid fertilizer during the growing season (spring through early fall), roughly once a month. Avoid fertilizing a stressed or dormant plant, as this can worsen root damage rather than help. If the plant is rootbound or the soil looks depleted and gray, repotting into fresh mix with slow-release nutrients may solve the problem long-term. Our houseplant fertilizer guide and how to repot a houseplant articles cover both processes in detail.
Frequently Asked Questions
Should I cut off yellow leaves?
Yes — once a leaf has turned mostly or fully yellow, it won't turn green again, so trimming it off lets the plant redirect energy to healthy growth. Use clean, sharp scissors and cut near the base of the petiole.
Is one yellow leaf normal?
Yes, occasional yellowing of a single older leaf is a normal part of the plant's natural aging process and nothing to worry about. Only be concerned if multiple leaves yellow at once or the pattern keeps spreading.
Will yellow leaves turn green again?
No, once chlorophyll breaks down and a leaf turns yellow, it's permanent for that leaf.
