Causes of Monstera Turning Brown

Monstera plants require special attention to stay healthy and beautiful. Sadly, you may miss a few factors and discover that your plant is already browning.

Overwatering Leads to Root Rot

While you may want to give them a lot of water, you must be careful not to overwater them. Too much love can cause them harm.

Too much water applied too frequently and in too large quantities, would rot the roots and cause them to stop working.

Continuous wetness suffocates the root system, preventing it from getting enough oxygen. The root cells gradually die and are no longer able to function properly.

Too much water around the root system fosters the growth of fungus, which is the primary cause of root rot disease.

Rotten roots are unable to absorb water or other nutrients, causing the leaves to discolor, sometimes turning yellow and eventually brown.

Lighting issues Cause Browning of Monstera Leaves

Your Monstera enjoys bright light, but not direct sunlight. Sunburn would result from exposing your Monstera to direct sunlight.

Sunburn is most common when growing Monstera in a southern room. Alternatively, when moving it outside in the summer. Your houseplant actually requires a lot of light to grow those large, beautiful leaves you adore.

On the other hand, if your monster does not get enough light, it will turn brown and produce smaller leaves. Light is required for leaves to produce food, as well as a green pigment called chlorophyll, which is responsible for the green color.

If your monstera isn’t getting enough light, it may not produce enough green pigment and food to keep the leaves healthy. As a result, the leaves of the mostera turn brown and yellow.

How To Fix Lighting Issue 

  • Remove the brown leaves; they will not restore.
  • To achieve the best results, place your Monstera in an east or west-facing window. Remember that your Monstera will thrive in bright, indirect light.
  • If your monstera is near a south-facing window, keep it at least 5-6 feet away (1-2 m). As a result, it only receives partial sunlight.
  • Also, for south facing window, use a sunblocking curtain. This should keep your monstera safe.
  • Make the mistake of leaving your plant outside unless it has been acclimatized.
  • If you don’t have access to natural light in your room, use artificial lighting to keep your monstera happy and healthy.

Monstera’s Leaves Turn Brown Because of Too Dry Soil

Monstera can withstand some drought because it grows naturally on tree trunks and climbs on them. Other mechanisms, such as aerial roots, help it collect water from the air.

We know that nutrients in the soil are soluble, so water is an essential component of plant nutrient intake. After absorbing nutrients, the root system transports them to other parts of the plant via a tissue known as the xylem.

This entire process requires water, and plat cannot continue the normal physiological process without it.

As a result, your monstera leaf cells will die, making them vulnerable to pests and diseases. Browning of the leaves is the result of all of the preceding actions.

Temperature Stress

As a tropical plant, your Monstera is used to temperatures between 68–86 °F (20–30 °C).

A sudden temperature change or exposure to harsh weather conditions can cause your plant to turn brown.

A sudden drop in surrounding temperature damages the tender leaf cells, resulting in the browning of the leaves. The length of time spent in the cold will determine the severity of the damage.

If the plant is placed on the balcony or outside of the room, cold drafts can cause significant damage to the leaves and overall plant.

Furthermore, the cold bite caused by direct airflow from the air conditioner damages the leaves.

Another way to get cold is to place the plant near windows, which can also cause damage if a cold draft enters through it.

How To Fix Temperature Issue

  • Keep your plants warm during the winter. If you notice that your room is extremely cold, you can easily move your monstera to a warmer location. Don’t leave your plants in the conservatory or unheated sunrooms during the winter.
  • Keep your Monstera plant away from heat vents and air conditioners. Also, avoid putting your plant near hot or cold windows. Extreme temperatures can cause significant damage to your Monstera.

Low humidity Causing Brown Monstera Leaf

Your Monstera plant has spent its entire life in high humidity. As a result, low humidity can cause their leaves to turn brown.

low humidity causes your plant to lose moisture through the leaves’ stromata. So, monstera requires more water than usual.

When the humidity is consistently low, it shows dehydrating symptoms. The tips of the leaves curl and dry out, turning brown.

Relative humidity between 50-60% is best suited for most houseplants.

How to Fix Low Humidity

If you live in an environment with a dry climate, there are certain tricks you can use to prevent your Monstera leaves from drying up.

  • Alternatively, you can change the position of your plant. Think of a place in your home with higher humidity and bright light. Oftentimes, our bathrooms have higher humidity. This is because of the wet environment created by the misty shower and sinks!
  • Grouping your plants or placing them in water-filled pebble trays can also help with humidity issues.
  • Misting is another way to raise humidity. To mist your monstera, simply spray water directly on the leaves. To maintain optimal humidity, do this several times per day. But i don like this process as it increases the threat of fungal infection.


Over-fertilizing also leads to brown leaves on the Monstera. In fact, over-fertilization would cause your Monstera plant to display certain symptoms like leaves turning black or brown.

Your plant might display symptoms of lack of nutrition and excess nutrition at the same time.

Because excess fertilizer can cause damage to your root,  preventing your plant from being able to absorb nutrients and water.

So, your monstera can show symptoms like yellowing or browning of leaves.

In addition, it will take some time for your monster’s root system to establish itself in its new home. This period of transition is referred to as transplant shock, and it results in the wilting and browning of your monster leaves.
