Why Do Indoor Plants Drop Leaves?

In this article, we will tackle each and every factor that might lead to the dropping of your plant’s leaves as well as how to fix it, and give you a list of plants that are pretty resilient which would be best for starter gardens.

If your house plant’s leaves have started to drop you could be looking at a variety of issues such as insufficient or overwatering, low humidity, too much fertilizer, pests, fungi, nutritional deficiencies, exposure to harmful chemicals, and more. Don’t worry. These issues do have a quick fix.

Why Do the Leaves of My Plant Drop and How Do I Fix It?

One thinks you need to remember is that at some point in your plants’ life, their leaves will drop. It is all part of their growth. But when it happens frequently and is unnatural, here are the few reasons why it could be happening.



The first thing you should check is how often you water your plant. It can go both ways. If you underwater your plant, chances are your plant is not getting enough moisture to continuously produce food.

Remember, water plays a vital role in photosynthesis. Plants that do not have enough water will eventually die, and the prelude to this is the falling of the leaves.

If you over water your plant, you will subject it to root rot. When you leave a plant sitting in very wet soil, the roots will have a hard time growing and it will eventually rot and even cause fungal problems.

What to do?

Water in moderation. Check the soil before watering your plant. If the soil is moist, you do not need to water it. Some plants may even require you to completely wait for the soil to dry before watering again. Whichever it is, it all falls down to knowing your plant better and following the recommended watering routine for its kind and type.

Low Humidity

Low Humidity

Most plants prefer moisture. When the air is very dry, the plant will consume the moisture stored in their leave and eventually dry them out which causes them to brown up and fall.

What to do?

There are two things you can do to resolve this issue. One is to create a humidity tray. This is a container with wet pebbles that you place within the vicinity of your plants.

The water from this tray evaporates and is absorbed by the plants it is surrounded by. Another option is to mist the leaves of your plants every once in a while. Some plants like air plant would require regular misting.


Too Much Fertilizer

When your leaves start getting brown and the sides and tips start to crisp, this is a sign that your plant is getting burned by over-fertilizing. By providing your plant with too much fertilizer, you are also inhibiting their ability to absorb water and making them act thirsty.

Ideally, plants do not need fertilizers during dormant periods of their growth. Giving them fertilizers during this time will just accumulate and cause the leaves to fall.

What to do?

Create a schedule for your fertilizing. Be sure it falls on the plants active months which are from spring up until fall. Beyond this time, it would be best to let your plant be on its own. If you have already placed way too much fertilizer, it would be best to drain it out by watering your plant thoroughly and letting the water through the pot.


Take a closer look at the leaves of your plants. If you notice tiny insects like scale insects, mealybugs, aphids or spider mites, they could be the cause of your plant’s dropping leaves. These pests feed on the nutrition of your plant and reduce its vigor.

What to do?

If there are just one or two pests on your plant, you can easily remove them with the use of a toothpick or a cotton bud. Infestations are a totally different issue.

In the event that your plant is infested, the first thing you have to do is isolate it from the rest of your garden and treat with insecticidal soap to kill off the pests.



A fungus is quite common in roots and is often the result of overwatering your plant. If you have noticed any fuzzy white material, or brown bumps on your plant, these are signs of fungus.

What to do?

There are dozens of home remedies to choose from. One of the most commonly used is the baking soda and liquid soap solution. This mixture adheres to the fungus and eventually kills it.

In more severe cases, you may need to use a fungicide that can be purchased at any horticulture store. Be sure to describe what the fungus looks like in order for you to get the right kind of treatment for your plant.

Remember to separate your diseased plant from the rest. Fungi reproduce through spores and could contaminate the other plants in your garden.

Nutritional Deficiencies

Nutritional Deficiencies

Contrary to what people know, plants actually have a lot of nutritional needs. Just like animals and humans, they would also need iron, nitrogen, potassium, phosphorus, calcium, magnesium, and sulfur. Should they have a deficiency in any of these elements, leaf dropping and discoloration occurs.

What to do?

If you have confirmed that your plant does have a deficiency, dilute the right amount of fertilizer with water and provide your plant with the nutrients it seems to be lacking. More often than not, fertilizers come with the complete package. Just be sure to use it in moderation. Too much of certain nutrients may cause harm to your plants as well.

Exposure to Harmful Chemicals

Exposure to Harmful Chemicals

Based on the study conducted by NASA (National Aeronautics and Space Administration) in 1989, plants are able to rid the environment of toxins that are harmful to humans such as formaldehyde, benzene, and carbon dioxide.

But there are chemicals that are also harmful to plants, and since they have no way of filtering out what to absorb and what not to absorb, they would end up taking in all the chemicals that are deemed harmful. For example, plants that are exposed to paint fumes and floor treatments may turn yellow and fall off due to the intensity of the chemicals contained in these products.

What to do?

Keep your plants at a safe distance from harmful and toxic chemicals. If paint work or any jobs need to be done using these chemicals, relocate your plants for the time being.



It is highly important that you do research on your plant before you buy them. In order to make sure that they do well under your care, you would need to mimic their native conditions. Let’s take a cactus for example.

We know that cacti thrive in hot conditions and would need minimal watering. Knowing this information, we know that the cold can cause harm to your plant.

What to do?

Keep your plants that are sensitive to temperature away from drafty windows, and heating vents. Place them in a neutral space away from factors that may directly cause an increase or decrease in temperature.

Environmental Changes

Plants that are newly bought will take some time to adapt. Most of the plants we purchase from nurseries have been grown in ideal conditions. When we move them into closed spaces like our homes or offices, we are changing what they are used to. The plants feel the stress, and it causes them to drop a few leaves.

What to do?

Allow your plant to adapt to its new environment. As much as possible, try to replicate the same setting it had prior to reaching home. This way you can slowly acclimate them into your space.

Which Type of Plant is Best for Low Light Apartments

Insufficient Light

When plants do not receive the right amount of light, they are unable to create their food. Some plants would even grow toward the light, while others would just begin to wilt away. It is important not to keep your plants in the dark space.

What to do?

If your home has no access to sunlight, it would be best to get your plants some grow lights. This way, they are able to produce food even though they are indoors. Otherwise, set your plants in a well-lit space or take them out every now and then. A little sun can do wonders for them.
