Yellow Monstera leaves usually mean the plant is stressed, but the cause depends on the pattern. One old lower leaf turning yellow can be normal aging. Several yellow leaves plus wet soil often points to overwatering or root rot. Pale stretched growth can mean low light. Speckling, sticky residue, or webbing suggests pests.
Do not fix every yellow leaf with fertilizer. Start with soil moisture, light, roots, and pests.

Quick Answer
Monstera leaves turn yellow most often from overwatering, poor drainage, root rot, low light, underwatering, repotting stress, pests, cold drafts, or natural aging. Check whether the soil is wet or dry, inspect roots if needed, and move the plant to bright indirect light.
Yellow Leaf Pattern Guide
| Pattern | Likely cause |
|---|---|
| one old lower leaf | natural aging |
| many lower leaves yellow, soil wet | overwatering or root rot |
| yellow leaves with dry crispy edges | underwatering or low humidity |
| pale stretched growth | low light |
| yellow speckles or webbing | spider mites |
| yellowing after repotting | transplant stress or root damage |
| yellow with black spots | root rot, cold, or leaf disease |
Overwatering and Root Rot
This is the most common cause. Monsteras like moisture but not soggy soil.
Signs:
- wet soil for many days
- yellowing lower leaves
- mushy stems or petioles
- sour smell
- black or brown roots
- fungus gnats
Fix:
- Stop watering.
- Check drainage.
- Remove plant if decline continues.
- Trim mushy roots.
- Repot in airy indoor mix.
- Use a pot with drainage.

Low Light
Monsteras tolerate indoor life but grow best in bright indirect light. Low light slows water use, which makes overwatering more likely.
Move closer to a bright window or add a grow light. For grow light setup, see Best Grow Light for Indoor Plants.
Underwatering
If soil is bone dry and pulling away from the pot, yellowing may follow drought stress.
Fix:
- water thoroughly until excess drains
- let the root ball rehydrate
- do not leave pot sitting in water
- adjust watering interval
Pests
Check undersides of leaves and stems for:
- spider mites
- mealybugs
- scale
- thrips
If you find insects, isolate the plant and read Indoor Plant Pest Control Guide.
FAQ
Should I cut yellow Monstera leaves off?
Yes, once they are mostly yellow. They will not turn green again. Leave partly yellow leaves if the plant still needs foliage and the cause has been fixed.
How often should I water Monstera?
Water when the upper part of the mix has dried and the pot feels lighter. Timing depends on pot size, light, temperature, humidity, and mix.
Can yellow Monstera leaves turn green again?
No. The goal is to stop new leaves from yellowing.
