One morning, I walked into my living room and noticed something strange—my Monstera’s once-vibrant leaves were turning yellow! At first, I panicked, but after some research and trial and error, I realized that yellowing leaves are just my plant’s way of asking for help.
So, why do Monstera leaves turn yellow? Monstera leaves may turn yellow due to overwatering, underwatering, improper lighting, nutrient deficiencies, or pests. Overwatering is usually the biggest issue, leading to root rot and yellowing leaves. A few small changes—like adjusting watering habits and checking light conditions—can bring your Monstera deliciosa back to health.
Curious about what’s happening to your plant? Let’s solve this mystery together!
Common Reasons of Yellowing Monstera Leaves
Overwatering
One of the top reasons Monstera leaves turn yellow is overwatering. If the soil stays too wet, the roots can’t breathe, and this leads to yellow leaves.
- Signs: Leaves turn completely yellow, and the soil feels soggy.
- Solution: Check the soil moisture. If it’s wet, let it dry out before watering again. Make sure your pot has drainage holes.
Underwatering
On the flip side, underwatering can also cause yellowing. When Monstera doesn’t get enough water, it struggles to absorb nutrients.
- Signs: Leaves have crispy yellow edges.
- Solution: Water your plant when the top inch of soil feels dry. Stick to a regular schedule.
Too Much or Too Little Light
Light is essential for your Monstera, but it needs to be just right.
- Too much light: Bright, direct sunlight can scorch the leaves, causing them to turn yellow and brown.
- Too little light: Without enough light, leaves may turn pale yellow.
- Solution: Place your Monstera in bright, indirect sunlight. Avoid direct sunlight that’s too harsh.
Nutrient Deficiency
Lack of nutrients, like nitrogen or magnesium, can also make Monstera leaves yellow. This happens because the plant isn’t getting what it needs to stay healthy.
- Signs: Older leaves turn yellow first.
- Solution: Use a balanced houseplant fertilizer every 4–6 weeks during the growing season.
Pest Infestation
Pests like spider mites and mealybugs can damage your plant, leading to yellow speckling or webbing on the leaves.
- Signs: Tiny yellow spots, webbing, or sticky residue.
- Solution: Wipe leaves with a mixture of water and neem oil. For severe infestations, use an insecticidal soap.
Troubleshooting and Diagnosing the Problem
Step-by-Step Guide
- Check the soil moisture: Is it too wet or too dry?

Common Myths About Yellow Leaves
- Myth: Yellow leaves always mean pests.
Truth: Many issues, like watering problems, are more likely. - Myth: Yellow leaves will turn green again.
