The majority of my readers are aware of the fact that I intentionally prolong my introductions whenever I can. I adore talking to my readers and imparting a wealth of knowledge to them.

This introductory section is where I keep myself motivated since I always strive to do the same for other people. But this time, I’ll make an effort to keep this section brief because I need to discuss a few crucial topics and don’t want to take up too much time.

Since corn plants are the most popular indoor plants, I’m sure many of you are extremely familiar with them, and many of you, I suppose, like caring for these plants.

However, problems might occasionally arise, and for this reason, I decided to create this essay and notify you of potential problems as well as potential solutions. Therefore, let’s begin.

Why are my Corn Plant’s Leaves Turning Brown?

One of the most popular indoor plants, the corn plant is renowned for needing little maintenance. Since this plant has such a stunning appearance, I have to say that I truly adore the way it appears. Dracaena fragrans.

Despite this plant’s simple maintenance requirements, problems might nevertheless arise sometimes. The most frequent problem that the majority of you who possess this plant may have is the bronzing of the leaves. Many of you, I assume, could fear since you don’t understand the causes of this problem. But don’t worry, I’m here to answer your questions.

I will now begin to discuss the causes of this problem and explain what you need to do in greater detail. What do I have in store for you? Let’s find out.

Low Humidity

When discussing maize plants, humidity is crucial. They thrive in humid locations where they can naturally develop, but they can also maintain good health inside in moderate humidity as long as it doesn’t go below 40%.

Therefore, it is very normal to observe brown leaves on your maize plant if it is inside and the humidity level is lower than 40%.

Get a digital hygrometer to track the humidity levels in your home in order to avoid this sort of problem.


Although corn plants are among the more drought-tolerant indoor plants, a lack of water can still harm the plant severely. Check the soil to see if it is dry or not if you observe dark leaf tips and are unsure whether it is caused by underwatering.

You should start giving your corn plant more frequent waterings if you determine that the brown leaves are a result of underwatering. Additionally, you may try watering your corn plant once the top one to two inches of soil is dry, being sure to use enough water every watering to completely wet the soil.

Inconsistent Watering

The corn plant won’t be able to adjust to the changing conditions if it receives inconsistent watering. It will generate a lot of healthy foliage in the early phases of growth, but if you don’t water it frequently, the foliage will struggle to stay healthy and you’ll see a lot of brown and crispy leaves.

As you can see, irregular watering may be the cause of brown leaves, therefore you should water your plant consistently and in the amount that it needs to avoid this problem.

Water Impurities

Chemicals found in tap water, such as fluoride and chlorine, can cause some sensitivity in corn plants. Therefore, watering the corn plant with tap water may result in toxicity as well as problems like discolored leaves.

As a result, you should filter the water you use to water your corn plant and check that it is free of fluoride and chlorine.


For the corn plant to grow healthily, fertilizers are crucial. However, you must be careful not to overfeed your corn plant with fertilizer. Lack of fertilizers might result in dark leaf tips, while fertilizer overuse can potentially have the same effect.

The simplest method to avoid problems of this nature is to fertilize your maize plant with a quick release fertilizer once a month. and a balanced, water-soluble fertilizer is the finest to use.

Excessive Light

They grow best in strong indirect sunlight because they are one of the most well-known indoor plants, but they are also quite tolerant of lesser illumination. However, this does not imply that they can survive in completely dark situations; if they only receive one or two hours of indirect sunlight, this might result in brown leaf tips.

Move your plant to a location where it may receive more indirect sunlight if you find that your corn plant’s leaves are becoming brown. By doing this, you will be able to address the problem.


Brown leaf tips on maize plants can be caused by pests including mealybugs, scale, aphids, and spider mites because they like sucking the sap from the plant’s leaves and stems. As a result, the leaf tips start to become brown since water and nutrients can’t get to them.

To prevent this sort of problem, you must inspect your plant more frequently to see if there are any insect infestations; if there are, you must treat your corn plant with pesticides.


Due to its changing environment, your corn plant may become stressed during repotting, which might result in part of its leaves becoming dark. Your corn plant will need time to adapt to the new circumstances.

If this happens, all you need to do is wait for your corn plant to adjust to the changing environmental circumstances; once it does, everything will be fine.
