Troubleshooting Why Your Monstera Leaves Are Turning Yellow And How To Save It

Monstera deliciosa, with its bold, split leaves and tropical flair, has become a staple in modern homes. But when those lush green leaves begin to yellow, it’s hard not to worry. Yellowing leaves aren’t just unsightly—they’re a signal. Your Monstera is communicating that something in its environment or care routine isn’t quite right. The good news? Most causes of yellowing are reversible if caught early and addressed properly. Understanding the underlying reasons—whether it’s overwatering, poor lighting, or nutrient imbalances—can mean the difference between a struggling plant and a thriving one.

Understanding Why Monstera Leaves Turn Yellow

Yellowing leaves, known as chlorosis in botanical terms, occur when the plant produces less chlorophyll. This can stem from a range of stressors. While a single yellow leaf on an older part of the plant may be natural aging, widespread or sudden yellowing indicates a deeper issue. The key is to assess patterns: Are the lower leaves yellowing first? Are the tips browning along with the yellowing? Is new growth affected? These details help pinpoint the cause.

Common culprits include improper watering, inadequate light, root congestion, pests, or nutritional deficiencies. Each factor influences the plant’s ability to absorb water and nutrients, disrupting metabolic processes. Addressing these issues systematically restores balance and allows your Monstera to regain its vigor.

Tip: Always check the soil moisture before watering—stick your finger 2 inches deep. If it feels damp, wait another day.

Primary Causes of Yellow Leaves and How to Fix Them

1. Overwatering: The Most Common Offender

Overwatering is the leading cause of yellow Monstera leaves. When soil stays saturated, roots suffocate and begin to rot. Damaged roots can't absorb nutrients or water efficiently, causing leaves to yellow and wilt—even though the soil is wet.

Symptoms include:

• Yellowing starting at the base of the plant
• Mushy, dark brown or black roots
• Foul smell from the soil
• Leaves feeling soft or droopy

To correct overwatering:

1. Stop watering immediately.
2. Remove the plant from its pot and inspect the roots.
3. Cut away any mushy, dark roots with sterilized scissors.
4. Repot in fresh, well-draining soil with perlite or orchid bark.
5. Use a pot with drainage holes and allow the top 1–2 inches of soil to dry between waterings.

2. Underwatering: A Less Obvious Issue

While less common than overwatering, underwatering also leads to yellowing. When a Monstera dries out completely, the plant pulls resources from older leaves to support new growth, causing them to yellow and crisp at the edges.

Telltale signs:

• Dry, crispy leaf edges alongside yellowing
• Soil pulling away from the pot sides
• Lightweight pot indicating dryness

Revive an underwatered Monstera by giving it a thorough soak. Submerge the pot in a basin of water for 10–15 minutes until the soil rehydrates. Going forward, establish a consistent watering schedule based on environmental conditions rather than a fixed calendar.

3. Poor Lighting Conditions

Monsteras thrive in bright, indirect light. Too little light slows photosynthesis, weakening the plant and triggering yellow leaves. On the flip side, direct sunlight can scorch leaves, leading to yellow patches or bleaching.

Optimal placement is near an east- or north-facing window, or a few feet back from a south- or west-facing one. If natural light is limited, supplement with a full-spectrum grow light for 8–10 hours daily.

Tip: Rotate your Monstera every few weeks to ensure even light exposure and balanced growth.

4. Nutrient Deficiencies or Excess Fertilizer

Yellowing can indicate a lack of essential nutrients like nitrogen, magnesium, or iron. Nitrogen deficiency typically causes overall pale or yellow lower leaves, while magnesium deficiency results in interveinal chlorosis—yellowing between the veins with green lines remaining.

However, over-fertilizing is equally harmful. Salt buildup from excess fertilizer damages roots and causes leaf burn, often seen as yellowing with brown tips.

Solution:

• Fertilize only during active growing months (spring and summer) with a balanced, diluted liquid houseplant fertilizer (e.g., 10-10-10).
• Flush the soil every 3–4 months by running water through the pot to remove salt accumulation.
• Supplement with Epsom salts (1 teaspoon per gallon of water) occasionally to address magnesium deficiency.

5. Root Bound or Poor Soil Quality

A Monstera that has outgrown its pot may show yellowing due to restricted root development. Roots circling the bottom of the container can’t absorb water or nutrients effectively.

Check for roots emerging from drainage holes or tightly wound around the root ball. Repot into a container one size larger using a chunky, airy mix—ideally a blend of peat, perlite, and orchid bark. This mimics the plant’s natural epiphytic habitat and promotes healthy root respiration.

“Plants don’t die from lack of fertilizer—they die from lack of oxygen to the roots.” — Dr. Linda Chalker-Scott, Horticulture Professor, Washington State University

Step-by-Step Guide to Reviving a Yellowing Monstera

Follow this timeline to diagnose and treat your Monstera methodically:

1. Day 1: Assess the Situation
   Observe which leaves are yellowing, their location, and any accompanying symptoms (browning, drooping, spots). Check soil moisture and recent care changes.
2. Day 2: Inspect Roots (if needed)
   If overwatering is suspected, gently remove the plant from its pot. Trim damaged roots and repot if necessary.
3. Day 3: Adjust Watering Routine
   Establish a moisture-check habit. Water only when the top inch or two of soil is dry. Use room-temperature water to avoid shocking the roots.
4. Day 4–7: Optimize Light and Humidity
   Move the plant to a brighter, indirect light spot. Increase humidity with a pebble tray or humidifier, especially in dry indoor environments.
5. Week 2: Begin Nutrient Support
   If no root issues are found, apply a half-strength balanced fertilizer. Avoid feeding if the plant is stressed or dormant.
6. Week 3+: Monitor Progress
   New growth should appear greener and more robust. Continue observing leaf color and texture. Remove severely damaged leaves to redirect energy.

Tip: Never remove more than 20% of the foliage at once—this can further stress the plant.

Do’s and Don’ts: Quick Reference Table

Place in bright, indirect light	Expose to harsh afternoon sun
Fertilize monthly in growing season (diluted)	Over-fertilize or feed during winter dormancy
Wipe leaves occasionally to remove dust	Use leaf-shine products that clog pores

Real-Life Example: Sarah’s Struggling Monstera

Sarah noticed her Monstera’s lower leaves turning yellow over several weeks. She was watering it weekly, assuming consistency was best. After reading about overwatering risks, she checked the soil—it was still damp 2 inches down. She stopped watering, moved the plant to a brighter corner away from AC airflow, and waited five days before giving it a slight drink.

After three weeks, new growth emerged, and the yellowing slowed. She eventually repotted it into a terra-cotta pot with a chunkier soil mix. Within two months, the plant produced two new fenestrated leaves. Sarah learned that “consistent” doesn’t mean “frequent”—it means responsive to the plant’s actual needs.

Frequently Asked Questions

Is it normal for older Monstera leaves to turn yellow?

Yes. It’s natural for the oldest, lowest leaves to yellow and die as the plant focuses energy on new growth. However, if multiple leaves yellow rapidly or upper leaves are affected, it signals a problem.

Can I cut off yellow Monstera leaves?

Yes, but only if they are fully yellow and dead. Use clean, sharp scissors to make a clean cut near the stem. Removing dying leaves helps prevent disease and redirects energy to healthy growth.

Why are my Monstera’s new leaves coming out yellow?

This is concerning and usually points to severe stress—such as root rot, extreme nutrient deficiency, or insufficient light. Immediate inspection of roots and adjustment of care conditions is crucial.
