Monstera is a resilient indoor plant that can survive harsh circumstances. Any plant parent should be concerned about black spots on Monstera, which can occur for several various causes. They will display marks of discontent on their leaves.
Monstera black spots don’t always portend disaster for the plant. Here are a few causes and some solutions on how to remove black spots on Monstera.
Why Does My Monstera Have Black Spots
Root rot is one of the most frequent causes of black spots on Monstera leaves. Overwatering, which leads to root rot, is a common mistake by well-intentioned plant parents.
Fortunately, even after getting too much water, they can be revived. Additional indicators of overwatering include:
- Yellow leaves or stems
- Soft, mushy stems
- Very squishy, damp ground
Remove it from its pot and brush off the roots if you think it has been overwatered. Remove any bad roots with scissors.
After cleaning the container with soap and water, add brand-new, fresh potting soil. To improve drainage, mix in a few bunches of perlite or gravel.
The finest pots to drain extra water are those with drainage holes. Trim their damaged leaves, then put them in the fresh soil.
Reduce the watering frequency and keep it in a location with a warm, indirect sun for drying.
Always verify with your finger or a moisture meter to avoid overwatering that the soil’s top layer is dry before watering.
Remember that Monstera will require less watering if it is in a colder or darker place rather than a warmer or brighter one.
Always check the soil before watering
On the other side, underwatering can also result in black spots on Monstera plants. They likely need water if you see the leaves are becoming light brown and appearing “crisp.” Ensure the soil is dry, then give them some extra water.
Place the plant in a container about two inches wider than the existing one. Because there is less substance to store water for the plant if they are root-bound, the soil dries up more quickly.
Repotting is necessary if roots are starting to poke through the soil and the container’s drainage hole.
Before you water the plant again, give it time to become used to its new home. Sadly, the dark edges do not disappear, but you may trim them to make them seem better.
The brown and black marks can be caused by sunburn in direct sunlight. Like in their natural environment, Monstera prefers bright, indirect light.
Keep them at least a few meters away from windows that face east or west, which offer sufficient illumination without being overly bright.
If the leaves are burning, move the Monstera farther from the window.
If there isn’t room next to the west or east-facing window, you might place your houseplant next to a south-facing window and cover it with a sheer drape.
If you want to keep them outside, put them beneath a porch to protect them from the intense mid-afternoon light while still getting some sun.
Rotate them every several days to ensure uniform development and to prevent one side from being more exposed than the others.
To prevent further damage to the Monstera, ensure their leaves aren’t in contact with the windows.
Sunburn can cause black spot
The leaf margins also become brown due to low moisture and dry air. Because Monstera is native to rainforests, they do well in humid conditions.
A humidifier beside your plants is an excellent method to improve humidity if you live in a dry area.
Place a tray of water close to your plant to boost humidity if you don’t have a humidifier. Water evaporation into the atmosphere gives indoor plants the necessary humidity.
Bacterial and fungal diseases can cause leaf spots. These patches frequently have a golden “halo” around them and are consistent in size.
As this disease may spread, remove the afflicted leaves and inspect any nearby plants for symptoms of the illness.
Keep the leaves dry to avoid bacterial and fungal illnesses. Although Monstera prefers damp environments, avoid misting its leaves.
Monstera plant black spots can be caused by bacterial and fungal illnesses from wet leaves. Use a tissue to clean up any water spilled on the leaves.
A plant owner’s worst nightmare is an insect infestation since they ruin your collection and bring discoloration.
These pests might be initially difficult to identify and challenging to eradicate. Guidelines to reduce the possibility of attracting bugs into your house:
- Before purchasing, check plants for insects, webbing, poison, or other damage. Avoid purchasing plants that exhibit pest activity.
- To stop spreading, quarantine new plants for a few weeks after bringing them home. If you have an infestation, this isolates the problem.
- Clean the dirt and containers.
- Avoid overwatering since wet environments attract insects.
- Regularly inspect your plants.
Check for damage on adjacent plants. If you find them, quarantine your plant immediately to stop the spread.
Wash the impacted plant under a stable stream of water from a shower head or hose to remove insects. Spray neem oil, and insecticidal soap, or rub alcohol on them afterward.
With no harm to the plant, this gets rid of the pests. To eradicate the infestation, repeat this procedure every few days for several weeks. Do not give up hope that Monstera will recover!

How To Remove Black Spots On Monstera
If you’re noticing black spots on Monstera leaves, don’t worry – there are ways to fix it. Here are a few tips:
- Make sure your plant is getting enough light. It needs plenty of light to stay healthy, so if yours isn’t getting enough, the leaves will start to turn black. Try moving it closer to a window or adding a grow light.
- Water your plant regularly and ensure the soil is moist but not soggy. A dry plant will start to show signs of stress, including Monstera leaf black spots.
- Check the pH level of your soil and adjust accordingly. A pH level that’s too high or too low can cause leaf damage and black spots. Use an at-home testing kit or take a sample of your soil to a garden center for analysis.
- Apply a foliar spray once a week until the black spots on the Monstera leaf disappear. Be sure to follow the instructions on the bottle carefully! This will help to protect the leaves and promote healing.
Do Monstera Leaves Grow Back After Cutting
Their leaves will not grow back if they are cut off from the plant. If you want the leaves to keep growing, keep a long stem attached to the leaf when you cut it off.
Alternatively, you can propagate a new plant from the stem.
If you want your plant to look full and healthy, it’s important to prune it regularly. Pruning involves carefully cutting away dead or dying leaves and any excessively long or damaged ones.
When pruning your Monstera, use clean, sharp shears or scissors. Pruning not only keeps your Monstera looking its best, but it also helps to encourage new growth.
New leaves will sprout from the cut stems, resulting in a fuller, healthier plant. If you’re hoping to achieve this effect, prune your Monstera regularly.
Be careful when cutting the leaves
How To Get Big Monstera Leaves?
There are a few things you can do to encourage bigger leaves on your Monstera plant:
- Place your plant in an area with bright, indirect light.
- Give your plant plenty of room to grow by repotting it into a larger pot every one to two years.
- Make sure the soil you use is well-draining and rich in organic matter.
- Water your plant regularly, but allow the soil to dry out slightly between waterings.
- Fertilize your plant monthly during the growing season.
- Prune back the stems of your plant to encourage new growth.
How To Save A Dying Monstera?
If your Monstera is dying, you can do a few things to save it. First, check the roots to see if they are rotted or unhealthy.
You will need to repot the plant in fresh soil. If you find any, you will need to treat them accordingly. Finally, make sure it is getting enough light and water.
If it is not, you may need to adjust its care routine. With a little effort, you should be able to save your dying Monstera.
Should I Cut Off Drooping Monstera Leaves?
It varies. The dark leaf won’t hurt the plant unless it is sick or rotting. However, it won’t become green once again.
It truly is a matter of judgment. I usually cut the severely damaged leaves off and clip the smaller brown spots from the leaves if I can.
It is in the plant’s best interest to leave browning on leaves alone as it still contributes to photosynthesis.
There are typical reasons why black spots on Monstera are developing:
- Watering too much
- Under watering
- Low humidity
- Inadequate fertilization
- Invasion of insects
The likelihood of overwatering a plant increases if the soil is moist and the stems are yellow and mushy.
It may be getting too much sun or not enough humidity if the leaves appear dry and crispy. Reduce watering frequency and transplant the plant into fresh, dry soil.
Regularly check your plants for indications of infection so you can start treating them immediately.
Remove them from the window and use a humidifier to raise the humidity level. Ensure they haven’t exceeded their container because doing so might result in underwatering.
