How To Treat Mold In Soil

Mix In Organic Fertilizer With Proper Ratio:

Are you sure that you mixed your fertilizer in correctly? It could be that there is either too high a concentration of fertilizer in one area and that this is inviting mold to grow.

The ideal ratio for most organic fertilizers can vary, though we do recommend a minimum of 1 part fertilizer to 10 parts soil. This will spread out the fertilizer particles so that they can feed the bacteria in the soil without giving them too much, too soon and inviting a nitrogen and/or nutrient glut.

Always make sure to mix the fertilizer in with the soil thoroughly. Adding fertilizer is best done when youre re-potting an existing plant with fresh soil, or starting a new garden with fresh soil. Mixing in by-product properly and at the correct ratio can be tricky with existing potted plants, as there is so little room to go around.

To Get Rid Of Mold On The Ground Transplant The Plant Into Another Pot

If you use new soil, new pots, and treat the plant with a fungicide, to remove the spores that have most likely reached the leaves and shoots, you have most likely solved the problem. That entails keeping all of these elements in mind.

The soil must be completely replaced with one that is sterile. If you save even a small portion of it and there are spores in it, it quickly contaminates the entire pot.

The pot is a transmission vector as well. If you use the same pot, it must be thoroughly washed and disinfected, as well as sprayed with an antifungal solution. You can immerse the pot in a solution of 9 parts water and 1 part chlorine for 10 minutes. Then thoroughly rinse.

Before replanting, the roots, leaves, and stems are thoroughly cleaned of contaminated soil.

Remove The White Fuzzy Mold Growing On The Soil

One of the easiest ways to eliminate white mold from plant soil is to remove it. White fuzzy mold only affects the top part of the potting mix. You can use a sterile spoon to remove 2 inches of soil carefully. Just dont allow any infected soil to fall back into the pot otherwise you will contaminate more soil.

The next step is to remove any evidence of mold from the stems and leaves. Take a damp cloth and gently wipe down all parts of the plant. Cleaning the whole plant helps ensure you remove all spores and traces of white mold.

The next step to get rid of houseplant soil fungus is to treat the plant with an antifungal treatment. Of course, there are many fungicidal sprays you can use. However, rather than fill your home with chemicals, its best to use natural fungicide solutions.

Use Natural Fungicide To Eradicate Mold From Plant Soil

Many natural ingredients are naturally antifungal and can help kill white fungus on the soil. The best natural fungicides for killing mold in houseplants are neem oil, apple cider vinegar, cinnamon powder, or baking soda. These can be just as effective at eradicating houseplant soil mold as their chemical counterparts.

Here is how to use natural fungicides to get rid of mold on plant soil:

While there are many commercial fungicides on the market, nature has a way of providing us with everything we need. Neem oil is a popular choice for preparing natural pesticides and fungicides. This oil comes from the Neem tree, and it has many uses, from skincare to insect repellent and plant treatment.

  • Half a gallon of water
  • 2 teaspoons of Neem oil
  • 1 teaspoon of liquid dish soap
  • Watering can

Combine half a gallon of water with two teaspoons of Neem oil and one teaspoon of liquid dish soap in a watering can and water your contaminated plant thoroughly.

Wait until the soil dries out between applications and water your plant with the natural fungicide once a month to prevent fungus growth. Neem oil does work to repel the fungus gnat and other houseplant pests, too.

How Does This Mold Develop

Mold growth occurs on almost any surface and isnt an indicator of cleanliness. When airborne spores land on a surface and have given the right conditions, i.e. a food source, moisture, warmth and oxygen, they begin to regenerate and grow.

Unfortunately, the potting soil you use for your container plants, especially when grown indoors, is a prime location. The spores feed on organic material found in the potting mix. Your ambient household temperature and the moisture you give your plants can act as a catalyst, causing the furry stuff to take up residence and begin multiplying.

Let Potting Soil Dry Out And Place In Sunlight To Get Rid Of Soil Mold

If you dont want the hassle of repotting a houseplant, you can let the plant soil completely dry out. Fungal growths and mold dont survive well in dry environments. Also, the suns ultraviolet rays kill fungus spores.

To kill mold on plant soil, put your houseplant outside in a sunny location. The heat from the sun and the dry conditions will help to limit or kill off the growth of white mildew. The reason why this method works well for mold is that mold generally lives in the top layer of soil. So, the heat from the sun should dry out the soil quickly. You only have to wait until the top 2 has dried.

If white feathery residue remains, you can safely scoop this away with a sterile spoon.

Another way to dry out plant soil to remove mold is to spread out the soil and leave it in the sun. However, because you will have to repot your plant later, it is best just to discard the soil and repot using a fresh potting mix.

What Causes Mold To Grow

Mold, like mildew, is caused by dark, moist conditions. This is actually how you end up with mold in the fridge on fruits and veggies because all mold needs to grow is liquid, nutrients, and darkness. In the case of plant matter in your fridge, it gets the moisture right from the fruit along with the nutrients, and a fridge tends to be dark, so it becomes the perfect environment.

The same translates to your houseplants as well. The soil of houseplants is full of nutrients, frequently wet, and does not always get enough light. Bright, warm conditions are not conducive to mold or fungus to grow on your plants or in the soil.

Give Them More Sunlight:

Nothing scares mold and mold-producing conditions better than good old fashioned Vitamin D. Put your plant closer to a window during peak sunlight hours and let their soil conditions dry out and warm up a bit.

Note: This may not be a good idea for some plants. Certain species require indirect or even very little sunlight and may start to wither, dry out or die if given too much sunlight.

How To Identify Dog Vomit

Early-stage: it appears as a bright yellow patch. This is the way this slime generally begins. It is very moist and compact .

Mature stage: after a few days, it matures, and it gets a pale yellow color. It dries out, and you can see some cracks in the surface

Final stage: it gets dark orange, and then finally brown. The spores are easy to be released .

When the mold is fully matured and dry, the spores inside are released into the air to spread the mold. So if you see a yellow blob in your pots, as the University of Arkansas suggests, what you probably have is the Fuligo Septica in its very early stages.

Fungicide Options For Powdery Mildew

You can apply fungicide treatments to infected plants to help manage severe infections. If you are interested in organic fungicides, consider neem oil, sulfur or potassium bicarbonate for powdery mildew. Unlike some chemical options, the fungi don’t become resistant to sulfur and potassium bicarbonate. Sulfur should not be used in hot temperatures above 85 degrees Fahrenheit as it may cause scorched leaves. If you use a sulfur spray, wait at least two weeks before applying neem oil.

You can also make a homemade powdery mildew spray with baking soda and water, notes West Virginia University Extension Service. Simply mix 1 teaspoon of baking soda in 1 quart of water and spray it on your plants. This will alter the pH and help to inhibit powdery mildew growth.

Chemical fungicides, such as those containing trifloxystrobin or azoxystrobin, can be used on many plants in your garden to help control powdery mildew. If the fungus is attacking your vegetable plants, make sure any fungicide you use is labeled for use on vegetables. Be sure to follow all warnings and application instructions on the product label.

Things You Will Need

  • An organic or chemical fungicide

  • Baking soda

What Causes Fungus On Soil Of Houseplants

There is white mold growing over the dirt in your indoor plants, and what looked nice and healthy yesterday now looks creepy and disturbing. Its important to know what causes fungus on soil of houseplants to ensure this doesnt happen again.

  • Powdery mildew

The primary fungus type to affect houseplants is saprophytic fungi or mycelium. This white, thread-like growth is harmless, even if it covers the entire soil surface. Another harmless type of this fungus is yellow fungal mold, which is also caused by saprophytic fungi. Botrytis fungus causes a harmful gray mold if left untreated.

Black and dark green patches are signs of sooty mold that result from insects feeding on the plants sap, and a light, flour substance on the plants leaves and stems is powdery mildew.

Preventing Mold In Houseplant Soil

Mulch And Fungus

Mold on the ground can occur for many reasons. Most often, you will find a white variety of mold in houseplant soil.

White mold appears on the surface of the soil if the room is cool enough. For example, you could often see such mold appear in basements or cellars where it is cold and damp.

The development of the colony begins after the spores get into the ground or on the plant itself. If your room air is highly humid then it will favor fungal growth. Besides, the accumulation or stagnation of water in the pot can be another reason for the mold in the soil.

A small drainage system in the pot can cause the holes to get blocked. As a result, excess moisture will remain in the root system of the plant. The soil will remain dump and cold which is an ideal condition for mold growth.


White mold is more likely to appear in the soil if it is sufficiently acidic or has many heavy elements in its composition. White mold may appear regardless of the variety of potted plants. For the same reasons, mold may appear on the soil surface in vegetable gardens.

In order not to fight against mold in pots, you can prevent its appearance. Heres how to do this:

  • Clean all the drainage holes at the bottom of the pot
  • Installing good drainage using brick chips, gravel, expanded clay
  • Instead of frequent small watering carry out watering when the soil gets dry out.
  • Use filtered water
  • Carry out regular watering of plants with a weak solution of manganese.

  • How To Treat A Mild Infestation Of Mold

    For a mild infestation of mold or fungus on the soil in your plants, all you need to do is remove the contaminated soil. Treating the problem before it gets out of hand will save you the trouble of fighting a massive infestation later. This will not just save you time, but also money in the long run.

    • Using a small spoon or scoop, you can remove the top ½ to 1 inch of soil. This will remove any fungi or mold that is currently in bloom or growing.
    • Be sure to replace any soil that you removed. You want to ensure that the roots of your plants are completely covered.
    • You can treat the soil with a light dusting of cinnamon or baking soda to prevent mold from recurring.
    • Be sure that you do not water the plant too heavily in the future as moist soil enables growth.
    • Wait until the top ½ inch to two inches of the top of the soil is dried out before watering .
    • Consider a new place to set your plant to ensure it gets more light to dry the soil faster.
    • Adding ventilation can help the soil to dry faster as well. This will help to prevent the mold from returning and an infestation from happening.

    Mild infestations will tend to be confined to just a few plants and have not had a chance to spread to all of them. It is better to treat all of your plants, even those that do not seem to be affected as of yet, just to prevent an issue before it arises. Even if the mold is just on the soil at this point, mold can travel on air currents, and it can eventually grow up to the leaves.

    Apply The Recommended Fungicides In Small Amounts

    Quality fungicides do not harm plants. Inferior fungicides, on the other hand, can add toxins to the soil that will later harm your plants. If you only use the recommended fungicides to treat your moldy potting soil, it will be good for use any day.

    When applying the fungicides, note that it should be done outside where there is ample air circulation. Adequate fungicides prevent the growth of new molds.

    To keep while mold from returning, provide good air circulation over your seed trays by running a fan.

    Consider watering your trays from the bottom instead of the top. Bottom watering brings moisture much faster to the roots but keeps the surface of the soil dryer so mold can multiply as quickly.

    Just remember never to let the trays sit in water for any longer than 20 minutes, or theyll absorb too much water and soak the soil anyway.

    Is Mold On Soil Bad For Plants

    Mold spores are always going to exist in and around natureand that includes the soil. Mold and fungi are a part of a healthy soil biome and are part of what makes soil what it is. However, as with almost anything, problems can arise when things get imbalanced.

    Depending on what type it is, mold on plant soil may or may not be bad for your plant. Some types of mold are relatively harmless, while others can cause disease. Regardless, an excess of fungi and mold growth usually indicates that your plant is growing in conditions that could definitely be harmful to it, especially in the long run. Lets look at some of those conditions that may cause mold growth on your houseplants.

    Use Soilless Seed Starter

    One of the easiest ways to cause a mold problem with your seedlings is using a seed starter mix that has organic matter like compost or soil.

    While these are both wonderful things for plants to grow in when you separate organic matter from the ground it comes out of balance with nature.

    Often bagged soil mixes contain bacteria and mold spores that can start growing in your seed trays with nothing to fight it off.

    Instead, use a soilless seed starting mix for starting seeds and young seedlings.

    Then once they are growing well you can transplant them into larger pots with a richer compost mix.
