Why Is My House Plant Moldy

Recently, I discovered a white and yellow mold or fungus on one of my houseplants, which astonished me. I understood that it may be somewhat unsettling if I weren’t used to seeing this. As a result, I decided it was time to discuss the causes of mold on indoor plants, how to prevent it, and how to effectively remove mold from an indoor plant.

Why are the plants in my house developing mold? Mold frequently grows on indoor plants as a result of inadequate drainage in the plant’s pot or container, excessive watering, inadequate ventilation, or insufficient sunlight. Houseplants with mold are frequently curable by removing the contaminated soil or chopping off the afflicted plant parts.

You won’t want to miss this article if mold is spreading on your indoor plants. I’ll go through how to recognize houseplant mold later. I’ll also go into greater detail regarding the circumstances that support the growth of mold and discuss some practical mold eradication techniques. Go on reading!

What can I do to get the mold out of my potted plants?

As a natural anti-fungal, cinnamon is revered by some gardeners. Simply remove the mold with a damp cloth, then sprinkle some cinnamon from your spice cabinet over the area.

Gaumond advises trying a DIY baking soda and water solution or a fungal spray for indoor plants if cinnamon doesn’t work. To make sure a solution isn’t overly potent, test it on a small portion of your plant. It’s crucial to address the causes of mold growth after you’ve removed and treated the mold. Discover the underlying issue, and then modify your plant care practices.

What brings about mold growth in plant soil?

If you know what to do, getting rid of mold is not a very difficult task. When most people discover mold, they automatically assume that their plant is doomed, but this is not the case. Common causes of mold growth include overwatering, inadequate drainage, and occasionally even the use of soil that is soaked with decomposing organic matter or that has already been contaminated.

It is too late to begin preventative care if mold is already present on the soil of your plants, but it is not too late to begin corrective measures. You must first get rid of the mold from the soil before you can begin to make it difficult for mold to grow. The following 5 methods will help you get rid of the ugly white mold in your plant’s soil.

Can you resurrect a rotting plant?

Since mold can swiftly spread from one pot to another, isolate your plant first. After that, scrape away the top several inches of earth in a well-ventilated area. That ought to work if the mold is not too old. You must completely repot the plant using an organic soil designed for potted plants if the mold is deeper than an inch or returns after a few weeks, advises Dubow.

Clean the interior of the pot with a squeeze of dish soap, some baking soda, and water before repotting the plant. To remove the mold from the pot’s interior, use a small amount of baking soda as a mild abrasive. Spray the infected leaves with water, then wipe each one with a paper towel after letting the pot dry fully (use a fresh towel for each leaf to prevent the spread of mold). Cut off any brown or dead leaves and throw them away. Then, sprinkle an organic fungicide on the underside of the leaves that are still there. “It’s simple to create your own: Mix one tablespoon of baking soda with a gallon of water, a half teaspoon of liquid detergent, and a tablespoon of horticultural oil “argues Dubow. Don’t omit the oil; it aids in the mixture’s adhesion to the mold. Keep your plant isolated for a few weeks to make sure the mold hasn’t returned, then water it after the soil has dried fully.

How can I get mold from the soil for my house plants?

  • For all newly acquired plants or when switching soil, use wholesome, sterile soil. For your indoor plants, think about using professional potting soil, which is rich in nutrients.
  • Try not to overwater plants. Too much water will encourage the growth of mold spores because mold prefers moist environments. Generally speaking, you need to water your plants whenever the top 2 inches or 1/4 of the soil is dry.
  • Regularly remove dirt or dust from the leaves and remove debris (such as dead leaves) from the soil. It may be easier for mold to grow if organic waste is left on the soil. Don’t forget to prune your plant’s dead branches as well.
  • Your plants should have a lot of light and airflow. Both natural and artificial light are necessary for the growth of your plant as well as to ward off mold. Airborne particles can readily move throughout the plant when there is a source of ventilation, like a fan set to low.

What is the fuzzy white substance on my houseplants?

Mealybugs frequently leave a white, cotton-like residue on plant leaves. The stems and leaves are where you’ll usually discover this residue. Either the mealybugs themselves or their egg sacs make up this residue.

The plant could also be covered in a sticky substance. This is honeydew that the mealybugs excrete. Ants may also be drawn to it.

Mealybugs are tiny, flat, oval-shaped white spots that appear on plant leaves. They also have a fuzzy or powdery appearance.

What kind of mold is it?

Your plant’s soil has a covering of mold that is probably an unharmful saprophytic fungus. Mold spores are present in all soil. However, your plant just so happens to be creating the ideal environment for the spores to flower, resulting in a white, fluffy covering.

Will it harm my plant?

The response is “no.” The saprophytic fungus won’t harm your plant on its own. However, it might also serve as a clear clue that your plant is undergoing hazardous conditions. For instance, it can be overly damp, not have enough airflow, or require more sunlight. Neglecting these warning signs is bad for your plant’s health in general.

How can I get the mold off my soil?

What time of year is it? Repotting is not a smart idea if your plant is dormant unless the soil has extensive mold growth. However, repotting is a simple choice during the growing season. Keep in mind that some plants, like the Hawaiian Palm, have “reverse” growing seasons, which means they are active in the winter and dormant in the summer. Before making a decision, do your study!

When did I last water the plants? If you decide to repot your plant, you must also rewater it. Repotting or rewatering your plant now, if it is still too wet, will cause root rot, which is almost always irreversible.

How much mold is there? You must take drastic steps if there is an infestation that includes mold on the soil surface and on the plant itself. On the other hand, there are a few quick, non-invasive ways if the soil just has a thin coating.

What ventilation and light conditions do my plants need? Mold is destroyed by the sun’s ultraviolet radiation. You may get rid of the fungus that is growing by leaving your plant in the sun for a day. The total care of your plant must be taken into consideration when making this choice. Additionally, if your plant isn’t excessively sensitive, placing it in a well-ventilated area can prevent mold from growing on the soil surface.

Why can plants develop white fuzzy mold?

Powdery mildew, commonly known as white fuzzy mold, is brought on by fungus spores in the air. The spores of the fungus typically adhere to a young leaf where they can begin to grow and germinate before quickly dispersing to other areas of the plant and neighboring plants. Indoor and outdoor plants can get sick, especially in warm, humid climates. A well-established plant is usually not killed by the mold, although it can get weaker, produce less greenery, and spread to other plants. In addition to using natural household solutions to eliminate the mold and stop it from spreading, increasing air circulation around plants can aid in preventing the spores from taking hold.

Is plant mold dangerous to people?

By removing mold from your indoor plants’ leaves, you can lessen your exposure to it. On living plants, mold is readily removed with a damp cloth. Never use a dry paper towel for this; doing so will cause the air to become more contaminated with mold spores.

When cleaning, swap out the paper towels to stop the accumulation of dust and mold from spreading. Use a spray bottle to make cleaning easier overall and make sure you’re cleaning in a well-ventilated location.

It will take some extra work to get the mold out of the soil itself. A spade or spoon should be used to remove the moldy top layer of soil, which should then be put into a plastic bag for convenient disposal.

After getting rid of any indications of visible mold, replace the top layer of stripped soil with fresh potting soil. To stop additional exposure to mold, you may need to replace more than just the top layer if the infestation has spread too far.

To prevent the growth of any mold spores, add a natural, organic anti-fungal product to your soil. A fantastic alternative that will prevent mold growth and is safe for the plant itself is cinnamon.

Put a thin layer of gravel on the bottom of your potting mix to prevent mold from returning and to provide a much better drainage system.

Place your indoor plants in a room with good ventilation. Make sure to open a window, use a dehumidifier, or turn on adequate ventilation fans because mold loves to grow in places with low ventilation.


Start with clean ground. If you buy a new plant, repot it in sterile soil because the soil may have been moldy when you brought it home from the store. Repot the plant after carefully removing all of the soil from its root ball.

Only water your houseplants when the soil is dry. A plant is typically exposed to mold when it is kept consistently damp. When you either overwater your houseplants or water on a schedule rather than by touch, this occurs. Before watering a houseplant, make sure the soil at the top is dry.

Increase the light. Making sure that indoor plants receive plenty of sunlight and, more importantly, that the sunlight falls on the soil is a terrific strategy to reduce moisture since mold adores the dark.

Insert a fan. As was said above, adding a fan will lessen your exposure to mold since excellent air circulation around the plant will prevent mold growth in the soil. This can be helped with a basic oscillating fan that is set to low.

Organize your indoor plants. Mold exposure is made worse by dead leaves and other organic debris. Regularly clip any dead stems and leaves.

Houseplants are not the only source of mold exposure. Mold is sly, which is the worst. Check these odd locations where mold can get the food and water it needs to grow to locate it:

Not to be overlooked are your home’s internal workings, which include:

The HVAC ducting, subflooring, heating and air conditioning filters, and drywall

The Centers for Disease Control and Prevention (CDC) state that exposure to mold can result in symptoms like stuffy nose, itchy eyes, wheezing, and skin rashes. Serious mold allergies can cause more severe symptoms in people, such as fever and shortness of breath. People with chronic lung conditions, such as obstructive lung disease, may potentially become infected with mold in their lungs.

Infants and young children are especially vulnerable to mold spore inhalation due to their immature immune systems. Infants spend more time on or near the floor than adults do, making them more susceptible to hazardous exposures and inhaling more dust. Scientists previously believed that lead poisoning in children was caused by them chewing on windowsills, but we now know that lead is actually the cause since it is a component of poisonous dust and mold. According to the Environmental Working Group, consuming these spores can impair the development of motor skills, memory, and learning.

Is vinegar safe to spray on houseplants?

According to the Alley Cat Allies website, white vinegar has a potent, repulsive smell and taste that can effectively keep cats away from sections of your home that you don’t want them to enter. Despite being harmless to humans and cats, vinegar is deadly to plants due to its 5% acetic acid content. According to the Northwest Center for Alternatives to Pesticides, spraying vinegar on houseplant leaves will damage their cell membranes. As a result, the leaves are destroyed, and if the vinegar seeps into the plant’s soil, it will kill it by drying up the roots.

Can having plants in your bedroom make you ill?

Houseplants are one of the best ways to make a place more welcoming. Living indoor vegetation frequently makes the difference between a home feeling welcoming and threatening, especially for metropolitan flats lacking outdoor space. Houseplants can be both a visual treat and a health benefit for the body. Indoor air is more contaminated than outdoor air due to the enclosed space. Indoor plants can assist in air purification by eliminating dangerous pollutants and volatile chemicals from the air that can worsen allergies and possibly make you ill. The best indoor air purifiers are common houseplants like English ivy, aloe vera, and snake plants. But take care: If consumed, these plants can poison you, your family members, and even your pets. Since children and animals are both prone to putting items in their mouths, they are especially vulnerable to deadly indoor plants.

Here are 10 indoor plants to avoid:

The serpent plant

The snake plant is one of the most well-liked indoor plants since it is a great interior air purifier, grows tall, thrives in practically any environment, and requires no special care. Snake plants are very effective at lowering formaldehyde (released into the air from such household items as particleboard and plastics). They also release oxygen at night rather than during the day, unlike most plants, which makes them a fantastic bedside companion for some fresh air before you go to sleep. The snake plant, also known as mother-in-tongue, law’s is regarded as a lucky plant in traditional cultures. However, if your pet eats it, it might not be so good luck because it can make dogs, cats, and rabbits salivate excessively, throw up, have diarrhea, and experience pain.

Aloe Vera 2.

Popular indoor plants like the aloe plant are effective in removing formaldehyde and benzene from the air, both of which are given off by some plastics and home cleaners. Aloe juice is scrumptious and has been used for years to treat burns and wounds. It also works wonders for the digestive system. While the aloe’s inside gel is the beneficial component, the plant’s exterior skin is somewhat poisonous and very irritating to the skin and digestive system. Your pet won’t die, but she’ll undoubtedly feel extremely sick as a result.

Daffodil 3.

The gorgeous yellow daffodil is a much-loved flower, particularly because it blooms in the spring, heralding the end of the long winter. However, appearances can be deceiving because they are also extremely toxic. Daffodil consumption can result in significant gastrointestinal problems, including as discomfort, vomiting, and diarrhea. Even worse, they may result in an increase in blood pressure, an unsteady heartbeat, trembling, and occasionally even death.

4. Lily

Even while lilies are among the most stunning flowers in existence, they are also among the most dangerous. Even if some lilies are poisonous, many of them are, such as the Easter lily, tiger lily, day lily, calla lily, and Asian lily. The calla lily can upset your stomach, make you throw up, irritate your skin, cause headaches, and distort your vision. Lily poisoning is extremely dangerous to cats. Lethargy, vomiting, and loss of appetite are among the symptoms. Without rapid medical attention, death is likely and kidney and liver failure are also possibilities.

Five Peace Lilies

The peace lily is not a true member of the lily family, despite its name. Formaldehyde, benzene, and trichloroethylene are three of the most prevalent indoor contaminants, and peace lilies are excellent at eliminating them from the air. They are also simple to maintain and can thrive in low light. They are extremely toxic and, unfortunately, can make people feel sick, vomit, have diarrhea, and have trouble swallowing in addition to burning and swelling of the lips, mouth, and tongue. The same applies to animals, with the addition of dehydration and the potential for renal failure to result in death.

Philodendron 6.

Philodendrons are hardy plants that require little maintenance and are excellent in removing formaldehyde from the air. Sadly, they are poisonous as well. They contain crystals of calcium oxalate, which are poisonous to both humans and animals. The majority of the time, philodendrons are only minimally hazardous to people, producing skin irritation as well as oral and intestinal swelling, but they are extremely hazardous to pets (cats more so than dogs), causing spasms, convulsions, discomfort, and swelling upon consumption.

Seven. Dieffenbachia

The dieffenbachia, commonly known as dumb cane, is related to the philodendron and has calcium oxalate crystals just like its cousin. Due to its size, this plant is more likely to be floor-bound and hence more approachable by children and animals. Ingestion can result in oral pain, increased salivation, throat burning, swelling, and numbness while being only mildly harmful to both humans and animals.

Pothos 8.

Another plant that consumes formaldehyde is the common and simple-to-care-for pothos. However, there is a solid reason why pothos is often referred to as devil’s ivy. Although pothos is only weakly toxic to humans, ingesting it can nevertheless result in mouth burning, skin irritation, vomiting, diarrhea, and swelling of the lips, tongue, and neck. It is significantly worse for animals because it produces similar symptoms but can also result in kidney failure and even death.

Oleander 9.

You might want to think again about keeping oleander around because it is a beautiful and delicate flowering plant. Even one leaf or one flower’s nectar might result in an erratic heartbeat, wooziness, and tremors in humans. Consuming oleander has been linked to fatalities, and kids are especially at risk. Arrhythmia, vomiting, and cold extremities are a few pet symptoms.

Caladium 10.

The South American plant caladium is sometimes known as elephant ear or angel’s wing. All portions of the caladium are dangerous to people and animals, despite being widespread and simple to care for. Any portion of the plant can burn along the digestive tract and cause swelling, difficulty breathing, speaking, and swallowing, as well as throat closing. Death could happen. Pets may exhibit symptoms such as excessive drooling, head shaking, trouble walking, difficulty breathing, nausea, and vomiting.

As long as care are taken, it is possible to get the advantages of many of these plants without running the danger of harm.

  • Ensure that pets and youngsters cannot access the plants (consider putting them in birdcages if you have a cat who likes to climb).
