The best way to deal with any mold contamination in houseplant soil is to prevent it in the first place. Most types of white furry fungus on houseplant soil are preventable with proper watering techniques and enough sunlight. Even growing plants under artificial lights can help kill plant mold.

Lets look at the best ways to prevent mold from causing ugly white fuzz on your houseplants.

More Tips To Prevent Potting Soil From Growing New Mold

When I had mold on my potting soil, I tried a lot of things and at one point, I just wanted to throw in the towel. However, I found that increasing the airflow and drying out the surface of the soil was the solution that worked best for me.

Ideally, performing all of these options at once is the best choice in fighting the mold: watering only when dry, improving drainage, and increasing airflow and sunlight. If this doesnt work, repotting can be a last-ditch effort.

If youve tried the above options and nothing is working for you, or if youd like some creative solutions, I have a few more ideas for you. Here are some other ways you can kill and prevent potting soil from growing new mold.

  • Vinegar
  • Baking soda
  • Cinnamon

Ive used a homemade vinegar spray to kill mold before, but it typically doesnt stay dead for long. For my moldy compost bin, I ended up using the vinegar spray to initially kill the mold and then placed a fan pointed at the top of the soil. This worked in just one day and the mold hasnt been back since. However, if youre using vinegar on your potted plants soil, know that too much vinegar can kill the plants, so be careful when trying this as a solution.

Baking soda is great at drying materials out , and sprinkling a little bit on the mold can dry it out and kill it. Again, if the soil is constantly wet, baking soda wont do much good. You should address the wetness first as its most likely the primary cause of the mold.

How Can You Tell The Difference Between Mold And Bacteria

A wall surface might, for instance, grow mould as a result of this. Compared to bacteria, they are simpler and smaller.

How To Prevent Mold On Plants

Commonly, white dusty mold on your plants soil is caused by prolonged moisture and poor drainage. You can prevent this mold from happening by making sure you follow the steps below:

  • Water early in the morning so your plants have time to dry out throughout the day
  • Use a container with good drainage
  • Use a quality potting mix thats sterilized
  • Water only when needed

How To Prevent Mold On Soil

1. The first step in preventing mold on houseplant soil is to start with new, sterile soil. While a lot of soil will claim to be sterilized, I never trust it. So, I sterilize any soil I will using.

Sterilizing soil can be done several ways but I use the oven method. Put soil in an oven safe container. You typically want to go 4 inches deep. Cover with foil. Place a meat thermometer into the center and bake at 180-200 F. for at least 30 minutes, or when soil temp reaches 180 F. . Anything higher than that can produce toxins. Remove from oven and allow to cool, leaving the foil in place until ready to use.

2. Do not water your houseplant unless the soil is dry. When you keep plant soil moist, it allows mold to grow. Allowing the soil to dry out between waterings helps prevent soil mold from growing.

3. Never let plants sit in saucers full of water.

4. Air circulation in your home is key to mold prevention period. It also really helps prevent mold on soil if you have good air circulation in rooms with houseplants.

5. Make sure your soil gets a hit of sun daily. All houseplants need light and if possible, try to get the sunlight onto the soil as well.

6. Remove dead leaves immediately. Decomposing leaves are food for mold and create an environment conducive to quick mold growth. Also, be sure to trim dead parts off of plants.

7. Dust your houseplants regularly. Mold spores travel in dust so keeping dust to a minimum is important.

Unfortunately, you cannot hold onto bags of potting soil forever.

When you repot new plants with it, they can become contaminated with the mold or fungus thats now living in the soil.

Sealing your potting medium bags tightly is essential to ensure that the contents are protected. That being said, potting soil should only be kept for 1 to 2 years and no longer. After this time, it starts to break down and loses its ability to retain moisture while draining correctly.

Why Mold Grows On Potting Soil

Mold is a vital part of nature as its job is to decompose matter in the soil.Almost all soils will have mold spores of some kind. The only exception to this is if youre using sterilized soil. By providing a consistently wet growing medium, like potting soil, mold will likely grow and will be hard to kill.

Like mosquitos, it can be hard to think that mold has a place in the circle of life . Still, it can be helpful to know that mold is a perfectly normal and helpful occurrence in nature.

Mold typically occurs on wet soil and is designed to decompose organic soil matter, further breaking down the nutrients into smaller pieces. These smaller nutrients can be used by beneficial microbes and better absorbed by the roots of plants. In short, mold helps provide nutrients for your potted plants!

By decomposing organic matter, molds play a big part in material biodegradation, enabling decay and rot necessary in all ecosystems.

However, even though mold in the wild is good, it doesnt mean that it should be allowed to grow indoors. This can pose risks to your plant .

What Should I Do About The Mold


Well, thats entirely up to you. Do you care if theres a bit of white fuzz on top of your soil? If not, then go ahead and let Mother Nature get on with it. Once the biomatter is completely decomposed in your soil, that mold will eventually disappear!

What Is Mold And What Does It Look Like On Houseplants

Youve probably seen mold a time or two in your life before, but do you know what it truly is?

Mold is a fungus. It comes in all sorts of colors, including purple, green, orange, white, or black depending on the source of mold youre dealing with.

Mold can form on almost any surface, from bathroom walls to upholstery and yes, your plants leaves or soil. All it takes for mold to grow is an environment thats rich in moisture.

Thats why mold develops more in your bathroom than in your living room or bedroom. The dampness and humidity of your bathroom as you shower can linger in the room if you have inadequate ventilation. That makes an ideal environment for mold.

Since you water your houseplants often, youre also giving mold a home around your plants.

You might not have known, but mold is incredibly common. No, not overgrowths of mold necessarily, but very small particles in the air.

Each time you step outside, youre breathing in microscopic mold spores that are floating around in the air. These arent dangerous to your health in small quantities unless you have a mold sensitivity or allergy.

In larger quantities though, mold can cause health maladies. You may have breathing difficulties if mold gets bad enough. For those with mold allergies, these breathing troubles can be even more pronounced.

Mold overexposure can also lead to skin irritation, itchy and red eyes, wheezing, and nose stuffiness.
