How To Successfully Identify White Mold Damage
White mold symptoms can vary based on the environment aswell as the type of plant. However, there are some commonly displayed ones suchas:
- At first, the stem may appear as having a water-soaked part. And at this point of the infection, your plant will still have beautiful appearance looking healthy above so it is very difficult to detect already occured damages.
- Wilting of stems, especially at the base accompanied by tan discolouration. Pay close attention as Infected stems may have tan to dark brown lesions.
And from these lessons, you will most likely find a dense, almost cotton-like growth forming under high humidity conditions.

Water Plants According To Soil Moisture
As creatures of habit, many of us have a routine for when we water our plants. Although there are good rules of thumb, checking the actual soil moisture is more reliable.
For example, watering plants every week could lead to overwatering if the plant has a slower absorption rate. The more accurate option is to check how moist the potted soil is.
In this case, the rule of thumb is only watering when 1/5 of the soil is dry which generally amounts to the top 1 2 inches of potted plant soil. To make things simpler, do not water your plants when the top layer still feels moist wait until it has become drier.

How To Manage White Mold
Once white mold has been introduced to a garden, the disease often reoccurs each year. Several cultural control practices can help reduce the number of plants affected.
- Choose plants with an upright and open form because they will dry more quickly than plants that lie along the ground or grow in dense clumps.
- Space plants far enough apart so air moves through them and dries them quickly.
- Use drip irrigation or soaker hose instead of sprinklers.
Remove all plants infected with white mold, as soon as the disease appears. Take care not to knock off any sclerotia in the process.
- Infected plants should be burned or buried in an area of the yard that will not be used for vegetable or flower gardening in the future.
- Infected plants can be composted only if the compost heats up to 148 to 158 F for a minimum of 21 days. If your home compost pile does not meet these standards, consider bringing infected plants to a municipal compost facility that does.
The plants below were evaluated for resistance by the University of Minnesota in 2011-2016.
In these plants, individual stems or shoots become infected and die back but the plant remains alive through the growing season.
- New Guinea Impatiens
- Sweet Flag
When grown in the garden, some stem infection could be found but plants did not wilt or die.
- Purple Millet Grass
- Elephant Ear
There are no symptoms of disease in these plants.
- Fiber Optic Grass
- Ornamental Reed

How To Prevent A Reoccurrence
First things first, reduce the frequency of waters if it’s in a dark location. In some cases, but not all, mould or fungi can still develop on dry soil, but usually is caused by poor soil or low light. The relationship between the frequency of irrigations and the light levels is significant. If you’ve got a plant in a shady setting with high humidity, you must allow the top few inches to dry out in between waters. This is because the combination of no natural lighting and overly saturated soil will significantly increase spore germination.
Poorly stored bags of used compost should never be used for houseplants. When there’s an open hole in the sack, moisture can be absorbed into the soil which will be a breeding ground for nasties to develop. If you’ve got leftover soil, be sure to keep it in a dry, dark environment with the hole sealed fully.
Regularly check for any signs of fungus development in the plant’s soil – even if it’s just a small portion that becomes moulded, be sure to remove the whole layer for a fresh batch. You can never be too safe with an infestation of pests or diseases, especially if you have them in close proximity to one another!
Does Vinegar Kill Mold
Vinegar does kill mold. In fact, it can tackle over 80 different species of mold, including most that grown on plant soil.
However, vinegar is also highly acidic. Spraying vinegar on a plant can cause burning of the leaves and flowers and it can make the soil too acidic.
Even though vinegar is effective in treating mold, it is not the best solution for treating mold on houseplants. There are safer natural ways that wont cause harm to plants.

White Mold On Houseplant Soil
If youve ever owned a houseplant, then it is likely that youve come across white mold growing on top of the potting soil. This white fuzzy mold is actually a fungus. Although its presence can indicate a problem with watering, it does not necessarily mean that the plant itself is sick or that it is going to die.
Basically, dont panic about it.

Although this fungus is harmless to humans, it does indicate that there could be a problem with the soil. Furthermore, it can be unsightly. Nobody wants to look at a carpet of white fuzz growing across the soil of their lovely house plant. This is because most of us have a natural aversion to mold. When we see it, we think of things like spoiled food and dampness. Both of which can harm us.
Bright Light Will Prevent Mold In Houseplant Soil
It is no secret that mold likes dark damp places. By brightening up the space where your houseplants are positioned, you can keep mold under control.
Some houseplants do not like too many hours of direct sunlight, so make sure you know what your specific houseplants lighting needs are before exposing it to too much sun. Place your houseplants in a bright room with decent natural indirect sunlight.
Open the blinds or curtains during the day and position the plants near the windows. To help the soil, you can position your houseplants so that the sun shines on the soil, for a certain amount of time each day.

What Is Causing This White Mold To Grow On My Plant
This white mold / fungus will typically appear if you have been over-watering the plant. Over-watering can lead to soil that is waterlogged. This creates the perfect conditions for fungus to thrive in. It loves moisture.
If you feel as though you havent been over-watering the plant, then it could mean that the pot or basket does not have sufficient drainage.
In a previous article, I wrote about mushrooms appearing on lawns. In that article, I pointed out that fungus will appear when there is organic matter for it to feed on. The exact same thing is happening in this case. The saprophytic fungi that appears on houseplants likes to feed on dead plant matter. For example, a dead leaf that has become embedded in the soil.
Another thing that people forget is that houseplants tend to get a lot of shade. And if theres one thing that we know about fungus, its that it loves shade.
To sum it up, fungus can appear when you combine waterlogged soil and decaying organic matter. Once you put these two together, youve created a recipe for white fuzz.

What Exactly Is Mold
Mold is essentially a type of fungus. It consists of small organisms that can manifest themselves in various colours such as white, green, purple, black or orange. Mold can reside both indoors and outdoors. It thrives, however, on moisture and can reproduce through spores that travel through the air.
Whether we realise it or not, were exposed to mold on a daily basis. In most cases the amount is so small that its harmless to us. Damp spots that appear in your home, however, could potentially cause sickness and its worth getting these checked by a specialist.
Mold in the garden, however, is not necessarily harmful. Most kinds actually help to break down materials in nature and transform them into compost for new growth. Spores that produce mold are actually present, to an extent, in various gardening mixes such as bark, peat, and moss. We cant see them until the conditions are met for spores to reproduce.
Repot The Plant To Get Rid Of Mold
If you are not willing to try to remedy the mold problem yourself, you might want to eliminate the problem completely, in one fell swoop. You can repot the plant in fresh, sterile soil and ensure that the old contaminated soil no longer forms part of the equation.
Simply remove your houseplant from its pot, clean the container out and then refill the container with fresh sterile soil.
Alternatively, to completely remove any remaining mold spores, you can soak the container in a solution of 9 parts water and 1-part liquid bleach, for around 10 minutes. Thereafter, simply rinse the pot out with regular dishwashing liquid and water. Once the container/pot has dried, you can fill it with soil and repot your houseplant.
Before replanting your houseplant, make sure that you have rinsed off the root system and cleaned the mold off the leaves. If any mold spores remain, you could end up with recontamination. You might want to spray the plant with a mild fungicide before repotting it too. Once you have repotted the plant you will need to ensure that you prevent mold growth by implementing a better watering and care routine.

How To Prevent Mold In Houseplant Soil
- Use healthy and sterile soil for all newly acquired plants or when changing the soil. Consider using commercial potting soil, which contains plenty of nutrients for your houseplants.
- Avoid overwatering plants. Mold thrives in moist conditions, so too much water will help mold spores to develop. As a rule of thumb, you should water your plants once the top 2 inches or ¼ of the total soil volume is dry.
- Remove debris from the soil and wipe off dust or dirt from the leaves regularly. Leaving organic debris on the soil can provide a better environment for mold to grow. Dont forget to trim dead parts of your plant, as well.
- Provide plenty of light and ventilation to your plants. Sunlight or artificial light is essential not only for your plants growth but also for repelling mold. A source of ventilation, such as a fan on low setting, allows airborne particles to circulate around the plant freely.
