Why Is My Monstera Turning Yellow?

Few houseplants are as recognizable as the Monstera deliciosa. With its dramatic split leaves and fast-growing tropical look, it’s easy to see why Monsteras have become a favorite among plant lovers. But when those beautiful green leaves start turning yellow, it can be frustrating — and sometimes alarming.

The good news is that yellow leaves are often your Monstera’s way of signaling that something in its environment needs to change. In many cases, the problem is completely fixable.

1. Overwatering Is the Most Common Cause

If your Monstera’s leaves are turning yellow, overwatering is usually the first thing to check.

Monsteras like moist soil, but they do not like sitting in soggy conditions. When the roots stay wet for too long, oxygen can’t properly reach them, which can lead to stress or root rot. Yellow leaves are often one of the earliest warning signs.

Signs of overwatering:

• Multiple yellow leaves at once
• Soft or mushy stems
• Soil staying wet for several days
• Brown or black spots appearing with yellowing
• A musty smell coming from the pot

How to fix it:

• Allow the top 2–3 inches of soil to dry before watering again
• Make sure the pot has drainage holes
• Empty excess water from saucers or decorative pots
• Consider repotting if the soil stays wet too long

A chunky, well-draining soil mix works best for Monsteras. Many plant owners use mixes containing orchid bark, perlite, and potting soil to improve airflow around the roots.

2. Underwatering Can Also Cause Yellow Leaves

While overwatering is more common, underwatering can also turn leaves yellow.

When a Monstera becomes too dry, the plant may sacrifice older leaves to conserve energy and moisture.

Signs of underwatering:

• Dry, crispy leaf edges
• Soil pulling away from the pot
• Drooping leaves
• Curling foliage
• Slowed growth

How to fix it:

Water thoroughly until water drains from the bottom of the pot. Instead of giving small amounts frequently, it’s better to deeply water the plant and then allow partial drying before the next watering.

3. Your Monstera Might Need More Light

Monsteras thrive in bright, indirect light. Too little light can weaken the plant over time, causing yellowing leaves and slower growth.

A Monstera placed in a dark corner may survive, but it usually won’t thrive.

Signs your Monstera needs more light:

• Long, stretched stems
• Smaller new leaves
• Slow growth
• Yellowing lower leaves

Best lighting conditions:

• Bright indirect sunlight
• Near an east or south-facing window
• Filtered light through curtains

Avoid placing the plant in intense direct afternoon sun, which can scorch the leaves.

4. Natural Aging Is Completely Normal

Sometimes yellow leaves are simply part of the plant’s natural life cycle.

Older leaves near the bottom of the plant eventually age and die off as the Monstera focuses energy on new growth.

If only one older leaf is turning yellow while the rest of the plant looks healthy, there’s usually no reason to panic.

You can trim the yellow leaf off with clean scissors once it’s mostly yellow or brown.

5. Nutrient Deficiencies Can Cause Fading Leaves

Monsteras are relatively heavy feeders during the growing season. If the plant hasn’t been fertilized in a long time, nutrient deficiencies may cause pale or yellow leaves.

Common symptoms:

• Light green or yellow newer growth
• Weak stems
• Smaller leaves

How to help:

Use a balanced liquid houseplant fertilizer every 4–6 weeks during spring and summer. Avoid over-fertilizing, as too much fertilizer can also damage roots and cause yellowing.

6. Stress From Temperature or Humidity Changes

Monsteras are tropical plants, so they prefer warm temperatures and moderate humidity.

Cold drafts, sudden temperature swings, or dry indoor air can stress the plant.

Avoid:

• Cold windows in winter
• Air conditioning vents
• Heating vents
• Temperatures below 55°F

If your home is very dry, especially in winter, adding a humidifier nearby can help.

7. Check for Pests

Pests like spider mites, thrips, and mealybugs can weaken Monsteras and cause yellow spots or leaves.

Look for:

• Tiny webbing
• Sticky residue
• Small moving insects
• Speckled or patchy discoloration

If pests are present:

• Isolate the plant
• Wipe leaves with insecticidal soap or neem oil
• Repeat treatment weekly until resolved

How to Keep Your Monstera Healthy

To prevent yellow leaves in the future:

• Water only when the top soil begins drying out
• Provide bright indirect light
• Use a well-draining soil mix
• Fertilize during the growing season
• Keep temperatures stable
• Inspect regularly for pests

Monsteras are resilient plants, and most yellowing problems can be corrected once you identify the cause.

Final Thoughts

A yellow leaf doesn’t always mean your Monstera is dying. In many cases, it’s simply reacting to watering habits, lighting conditions, or normal aging.

Pay attention to the pattern of yellowing and the overall health of the plant. Once you adjust the care routine, your Monstera will often bounce back with healthy new growth.
