Monstera leaves have the tendency to turn black due to various reasons.
And if you don't know the right reason, your plant can turn entirely black and die.
So, what are these causes, and how can you save your plant?
Check out the following detailed guide to resolve this issue and encourage new growth in your plant.
Why Is My New Monstera Leaf Turning Black?
As mentioned earlier, there are several reasons that can cause the blackening of Monstera leaves.
But the most common reasons include -
- Not Enough Light
- Too Much Light
- Poor Air Circulation
- Too Much Fertilizer
- Fungus Attack
Any or a combination of these reasons can lead to the black leaves issue in this plant.
Now that you know the causes, let's learn more about the solutions.
7 Things To Do When New Monstera Leaf Turns Black
Here's what you should do when you see the leaves of your plant turning black.
1. Move The Plant To A Better Location
This is one of the care tips that is often overlooked.
When the plant doesn't get enough light, the leaves turn black.
And this can happen when you keep the plant in the darkroom for too long.
So, it makes sense to find a better location for the plant.
Move it to a place where it can get bright, indirect sunlight.
This type of light is perfect for Monstera plants.
2. Check If You Are Overwatering The Plant
Having a black leaf on Monstera can also be a sign of overwatering.
When you water the plant too often, the roots start to rot.
To avoid this problem, you should consider changing the watering schedule for your plant.
3. Improve Air Circulation Around The Plant
Another possible reason for black leaves on Monstera can be the lack of air circulation.
When the plant doesn't get enough air, it starts to suffocate.
Eventually, the plant becomes weak, and the leaves start to turn black.
To resolve this issue, try to improve the air circulation around the plant.
But what does that mean?
It means you should avoid keeping the plant in a tight space.
And if possible, you should also consider using a fan to circulate the air around the plant.
This is also important in keeping the plant dry and preventing any fungal growth on the plant.
So, it has many benefits for the plant.
4. Check The Fertilizer Schedule
I know you must be using the best fertilizer for Monstera.
But are you using it as per the schedule?
If you are overdoing it or using it more frequently than required, it can lead to the blackening of leaves.
So, check the fertilizer schedule.
Try to adjust it as per your plant's need and see if that helps.
5. Inspect The Plant For Pests
Although the black leaf issue is mostly related to fungus or overwatering, it can also be caused by pests.
Pests like mealybugs, spider mites, and scale insects are known to feed on the leaves of Monstera.
And this can lead to black spots or black leaves on the plant.
So, you must inspect the plant for any signs of pests.
If you find any, you should take immediate action to eliminate them.
You can even use a pesticide to kill the pests.
There are many organic pesticides available in the market that will not harm your plant.
6. Check For Fungus Or Bacteria
Fungus or bacteria can also cause black leaves on Monstera.
This usually happens when the plant is overwatered or kept in a humid environment.
To deal with this issue, you should try to improve the drainage of your plant.
You can also spray the plant with a fungicide to get rid of the fungus or bacteria.
This is more effective than trying any preventive measure.
7. Prune The Affected Leaves
Last but not least, you can also try pruning the affected leaves.
It does sound like a radical solution.
But, it can actually help the plant produce new leaves in the coming weeks.
When you prune the plant, you essentially get rid of the affected parts.
Therefore, it makes it a little easier for the plant to develop new growth.
The pruning task can also be performed before spraying the plant with a fungicide.
Pruning is also a great way to improve air circulation.
So, these are some of the things you can do to deal with black leaves on Monstera.

To do this, you need to cut the leaf to the point where it meets the stem.

You just have to repeat the process for each leaf.
