Monstera Leaves Turning Yellow? Here’s What to Do
Monstera leaves turning yellow? It is one of the most common problems plant owners face, but it is also one of the easiest to fix. This guide covers all the possible causes—from watering issues to pests—and gives you simple, step‑by‑step solutions to bring your plant back to health. #MonsteraCare #YellowLeaves #HouseplantHelp #PlantParent #IndoorGardening
My first Monstera was a gift, and I was determined to keep it alive. I watered it every week like clockwork. Within a month, the beautiful green leaves started turning yellow, and I had no idea why.
I panicked, changed everything at once, and made things worse. Over time, I learned that yellow leaves are not a death sentence. They are your plant’s way of telling you something is wrong. Once you know what to look for, fixing it is simple.
First, Is It Just Old Age?
Before you panic, check which leaves are turning yellow. Monsteras naturally shed their oldest leaves as they grow new ones. If you see one or two yellow leaves near the bottom of the plant, and the rest look healthy and green, it is likely just old age. Leaves have a limited lifespan. You can simply snip those off, and your plant will be fine.
But if you see several yellow leaves, or if the yellowing is happening on new growth, then it is time to play plant detective.

The 7 Most Common Causes (And Exactly How to Fix Them)
1. Overwatering (The #1 Culprit)
Every expert agrees: overwatering is the most common reason for yellow Monstera leaves. Monsteras need oxygen at their roots. When the soil stays wet for too long, the roots cannot breathe. They start to drown and rot. A rotting root cannot take in nutrients, and the leaves turn yellow as a distress signal.
How to spot it:
- The yellow leaves are often older, lower leaves.
- The soil feels soggy and wet days after you last watered.
- The pot feels very heavy when you lift it.
- In bad cases, you might see brown or black spots on the leaves.
How to fix it:
- Stop watering immediately. Let the soil dry out completely.
- Check the soil: Stick your finger 1 to 2 inches into the soil. If it feels wet, do not water. Let the top 50 percent of the soil dry out before you water again.
- If it is mild: Just let the soil dry out and wait longer between waterings.
- If it is severe (many yellow leaves): You need to repot. Gently take the plant out of its pot and look at the roots. Healthy roots are firm and white or pale. Rotten roots are brown, mushy, and may smell bad.
- Trim the rot: Use clean, sharp scissors to cut away all the mushy, rotten roots. Only leave the healthy ones.
- Repot: Put the plant in fresh, dry, well‑draining soil in a clean pot that has drainage holes. Do not water for a few days to let the cut roots heal.
My golden rule: It is almost always better to underwater a Monstera than to overwater it. When in doubt, wait a day.
2. Underwatering (The Opposite Problem)
It sounds strange, but not giving your Monstera enough water can also turn leaves yellow. While overwatered leaves turn all yellow, underwatered leaves often get dry, brown, and crispy on the edges first, and then the yellow spreads.
How to spot it:
- The soil feels bone dry.
- The pot feels very light when you lift it.
- The yellow leaves feel dry and brittle, not soft and mushy.
How to fix it: This is an easy fix. Just give your plant a thorough, deep watering. Water it until you see water flowing out of the drainage holes at the bottom. This ensures the water reaches the entire root ball. Then, establish a regular watering routine so the soil never dries out completely.
3. Light Problems: Too Little or Too Much
Your Monstera is a tropical plant that lives on the jungle floor. It is used to bright, indirect light. Direct sunlight or deep shade will both cause problems.
Too little light: If your Monstera is in a dark corner, it cannot photosynthesize enough food. The leaves will turn a pale, sickly yellow, and the spaces between the leaf holes may not develop properly.
Too much light: Direct, hot sunlight can scorch the leaves. This looks like yellow or brown patches, almost like a sunburn.
How to fix it: Move your plant to a spot with bright, indirect light. An east‑facing window is perfect. A spot a few feet away from a south or west‑facing window also works great.
4. Poorly Draining Soil
Even if you water correctly, heavy soil can hold water too long and cause root rot. Monsteras need loose, fast‑draining soil.
How to fix it: Plant your Monstera in a chunky potting mix blended for aroids. You can also add chunks of orchid potting bark or chunky vermiculite to a regular potting mix. This allows better aeration for the roots and helps the soil drain more quickly.
5. Nutrient Deficiency (A Hungry Plant)
Monsteras are fast growers and can quickly use up the nutrients in their potting soil. If you have not fertilized in over a year, your plant may be hungry. A common sign is a nitrogen deficiency, which causes the older, lower leaves to turn yellow first. A magnesium deficiency shows up as yellowing between the leaf veins.
How to fix it: Feed your plant! During the spring and summer growing season, use a balanced liquid fertilizer (like a 20‑20‑20) at half the recommended strength, about once a month. Do not fertilize in the fall and winter when the plant is resting.
My natural fix: I personally use a very mild, organic liquid fertilizer with worm castings. It is gentle and hard to overdo. My Monstera has not had a yellow leaf from hunger since I started using it.
6. Pests
Tiny bugs like spider mites, thrips, or mealybugs can suck the sap right out of your Monstera’s leaves, causing them to turn yellow. Look closely at the leaves, especially the undersides, for any tiny moving specks, webbing, or small brown bumps.
How to fix it:
- Isolate the plant immediately so the bugs do not spread to your other plants.
- Wipe the leaves down with a soapy water mix (a few drops of mild dish soap in a spray bottle).
- For bigger infestations, use neem oil or an insecticidal soap according to the package directions.
7. Root‑Bound or Compacted Soil
If your Monstera has been in the same pot for years, its roots may have filled the entire container. When the roots get too crowded, they cannot effectively absorb water and nutrients, which leads to yellow leaves.
How to spot it:
- Roots are visibly growing out of the drainage hole at the bottom of the pot.
- The plant dries out very quickly after you water it.
- The plant is top‑heavy and has stopped growing.
How to fix it: Repot your Monstera into a pot that is 1 to 2 inches larger in diameter with fresh, well‑draining soil.
Quick Reference Table: Diagnosis and Treatment
| Symptom | Cause | Immediate Action | Prevention |
|---|---|---|---|
| Soft, pale yellow leaves, wet soil | Overwatering | Stop watering. Let soil dry. Check for root rot. | Water only when top 1‑2 inches of soil are dry. |
| Crispy, dry yellow leaves, bone‑dry soil | Underwatering | Water thoroughly. Let water drain. | Water when top few inches of soil feel dry. |
| Pale, stretched yellow leaves | Too little light | Move to brighter spot with indirect light. | Place in bright, indirect light. |
| Yellow/brown patches, like sunburn | Too much direct sun | Move to spot with filtered light. | Avoid harsh afternoon sun. |
| Yellowing between leaf veins | Nutrient deficiency | Fertilize with balanced liquid fertilizer. | Fertilize monthly in spring and summer. |
| Yellow speckles, webbing, or bugs | Pests | Isolate. Wipe with soapy water or neem oil. | Inspect regularly. Isolate new plants. |
| Roots growing out of drainage holes | Root‑bound | Repot into larger pot with fresh soil. | Repot every 1‑2 years. |
What to Do With the Yellow Leaves
Once a leaf has turned mostly yellow, it will not turn green again. Those yellow leaves are just sucking energy from the rest of the plant. My advice is to cut them off.
Use a clean, sharp pair of scissors or pruning shears. Cut the yellow leaf’s stem as close to the main plant’s base as you can. This will make your plant look much better and let it focus its energy on growing beautiful new green leaves.
My Final Golden Rules for a Happy, Green Monstera
After killing one plant and reviving two others, here are the rules I live by now.
- Do not water on a schedule. Check the soil with your finger before you water. When the top 1‑2 inches are dry, it is time to water.
- Use well‑draining soil. Regular potting soil is too heavy. Mix in perlite, orchid bark, or coco coir so the water flows right through.
- Give it bright, indirect light. A few feet away from a sunny window is its happy place.
- Wipe the leaves. Monstera leaves are big and collect dust. Wipe them down gently with a damp cloth every few weeks so they can soak up all the light they need.
- Do not panic. A few yellow leaves are a sign to pay attention, not to give up. Every plant parent goes through this. Learn from it, and your plant will be even stronger.
The Bottom Line
Monstera leaves turning yellow is not the end of the world. It is your plant’s way of telling you something is wrong. The key is to look at the leaves, check the soil, and figure out the cause. Overwatering is the most common culprit, but underwatering, light problems, nutrient deficiencies, and pests can also be the issue.
With a little observation and these simple fixes, you will have those big, beautiful green leaves back in no time. Your Monstera wants to live. You just need to listen to what it is telling you.
