Understanding Monstera Plants: Why They Are So Popular
Before we dive into the reasons behind monstera leaves turning yellow, let’s take a moment to appreciate why Monstera plants are such a popular choice for plant enthusiasts worldwide. Known for their dramatic, split leaves and overall striking appearance, Monstera deliciosa and its varieties like Monstera adansonii have become iconic houseplants.
These plants are native to tropical regions, where they grow in humid, shady conditions. They thrive in bright, indirect light and need consistent care to stay healthy.

Whether you’re a Monstera expert or a beginner in the world of houseplants, learning to care for them properly will ensure they remain healthy and vibrant. And don’t forget: the joy of having a flourishing Monstera in your space is totally worth it!
The Common Causes of Monstera Leaves Turning Yellow: What You Need to Know
There are several potential reasons why your Monstera plant might be showing signs of stress, particularly when you notice monstera leaves turning yellow. Let’s break them down one by one to help you identify the root cause and take action.
Overwatering: A Leading Cause of Yellow Leaves
One of the most common causes of monstera leaves turning yellow is overwatering. Monstera plants are sensitive to excess moisture, and overwatering can lead to root rot, which prevents your plant from absorbing nutrients properly. When this happens, the leaves start to yellow as a sign of distress.
Signs of Overwatering:
- Yellowing leaves, particularly at the bottom of the plant
- Soil that is consistently wet or soggy
- A musty or rotten smell coming from the soil
- Roots that appear brown or mushy when checked
To fix this issue, ensure that your Monstera is planted in well-draining soil and that the pot has proper drainage holes. Water the plant only when the top inch of soil is dry, and avoid letting the plant sit in water. In extreme cases, you may need to trim away any affected roots and repot your Monstera in fresh soil.
Underwatering: When Your Monstera is Thirsty
On the flip side, underwatering can also cause monstera leaves turning yellow. When you forget to water your plant regularly, the leaves may start to droop and yellow due to dehydration. Unlike overwatering, underwatering tends to affect the older leaves first.
Signs of Underwatering:
- Yellowing leaves, especially on the lower part of the plant
- Dry or crispy leaf edges
- Wilting or drooping leaves
To solve the issue, adjust your watering schedule. Typically, Monstera plants need watering every 1-2 weeks, but this depends on the size of the plant, the climate, and the pot’s drainage. Make sure the soil is moist but not soggy, and avoid letting it completely dry out for long periods.
Nutrient Deficiencies: Feeding Your Monstera Right
Another culprit behind monstera leaves turning yellow is a lack of nutrients. If your Monstera is not getting the right balance of nutrients, especially nitrogen, the leaves may begin to yellow, starting with the older ones.
Common Nutrient Deficiencies:
- Nitrogen deficiency: Causes older leaves to turn yellow while younger leaves stay green.
- Iron deficiency: Causes yellowing between leaf veins, a condition known as chlorosis.
- Magnesium deficiency: Causes yellowing of older leaves with green veins.
To fix this, feed your Monstera with a balanced fertilizer, specifically one that’s high in nitrogen and contains other essential minerals. Be sure to follow the instructions on the fertilizer packaging to avoid over-fertilizing, as this can lead to more problems.
Low Light Conditions: Insufficient Sunlight Can Stress Your Monstera
Low light can also contribute to monstera leaves turning yellow. While Monstera plants can tolerate lower light levels, they thrive in bright, indirect sunlight. If they’re placed in a spot with insufficient light for extended periods, their leaves will begin to lose their vibrant green color.
Signs of Low Light Stress:
- Yellowing leaves, particularly on the side farthest from the light source
- Slow growth or leggy appearance
To resolve this, move your Monstera to a brighter location with indirect sunlight. If natural light is scarce, consider investing in a grow light to supplement their light needs.
Pests and Diseases: Unseen Threats to Your Monstera
Pests such as spider mites, aphids, and scale can damage Monstera plants, causing monstera leaves turning yellow. These pests feed on the plant’s sap, leaving the leaves weak and discolored. Additionally, diseases like fungal or bacterial infections can also lead to yellowing.
Signs of Pest Infestation:
- Sticky residue on leaves (from aphids or mealybugs)
- Webbing between leaves and stems (spider mites)
- Discolored, deformed, or spotted leaves
To prevent pests, inspect your Monstera regularly for signs of infestations. If you notice any, remove the pests manually or treat the plant with an insecticidal soap or neem oil. For fungal or bacterial infections, trim away affected areas and apply appropriate plant treatments.
How to Fix Yellowing Leaves on Your Monstera: Step-by-Step Solutions
Now that we’ve identified the causes of monstera leaves turning yellow, let’s walk through some practical solutions to help you restore your plant’s health and prevent future issues.
Fixing Overwatering and Root Rot
If overwatering is the issue, the first step is to check the roots for signs of rot. If the roots are mushy or black, trim them away with sterile scissors. Repot the Monstera in fresh, well-draining soil, and ensure that the new pot has drainage holes to prevent water from accumulating at the bottom.
Fixing Underwatering: Rehydrate Your Monstera
To fix an underwatering issue, thoroughly water your Monstera and allow the water to drain from the pot. Make sure the soil is evenly moist but not soggy. In the future, water the plant consistently, allowing the top inch of soil to dry out before watering again.
Fixing Nutrient Deficiencies
If a nutrient deficiency is the cause of monstera leaves turning yellow, fertilize your plant with a balanced, water-soluble fertilizer. Look for a formula that’s high in nitrogen and contains iron and magnesium. Feed your Monstera once a month during the growing season, but reduce the frequency during the winter months when the plant is dormant.
Fixing Low Light Conditions
If your Monstera is in a low-light spot, move it to a brighter location with indirect sunlight. If natural light is insufficient, use a grow light to provide the necessary illumination. Keep in mind that direct sunlight can scorch your Monstera, so opt for a spot with filtered light.
Treating Pests and Diseases
To treat pests, regularly inspect your Monstera for signs of insects and wipe down the leaves with a damp cloth. For a more thorough approach, use insecticidal soap or neem oil to treat infestations. If the plant is suffering from a fungal or bacterial infection, remove affected leaves and apply the appropriate treatment.
Conclusion: Bringing Your Monstera Back to Life
There’s no need to panic if you notice monstera leaves turning yellow. With the right knowledge and care, you can address the underlying issues and help your Monstera thrive once again. Whether it’s adjusting your watering routine, improving light conditions, or treating pests, there are solutions available.
Remember, each Monstera variety, from Monstera deliciosa to Monstera adansonii and beyond, has specific care requirements. By tailoring your care routine to meet these needs, your Monstera will flourish, providing you with lush, green leaves for years to come.
Don’t let yellow leaves discourage you – it’s all part of the plant care journey! Keep learning, keep caring, and your Monstera will reward you with its beauty.
