Mold concerns are caused by moist potting soil and inadequate drainage. Bad Drainage Long-term sogginess in the potting soil causes the plant to start dying and may result in mold growth. Mold spores thrive in the decaying roots, stems, and leaves.
How can mold in succulent soil be removed?
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.
Why does my soil have a white fuzziness?
Most likely, the white fluffy substance on the plant soil is a saprophytic fungus that is not harmful. The following factors can all contribute to fungal issues (mold) on the plant soil: excessive water, inadequate soil drainage, polluted potting soil, and a lack of sunlight. Low light and moisture provide the “ideal setting for the growth of white mold on home plants.
Tiny minuscule spores that make up the mold fungus begin to grow and thrive under specific conditions. The mold’s color can change depending on what caused the potting soil infection.
White fungus on soil
White growths on the ground that resemble threads are saprophytic fungus, according to the Royal Horticultural Society. Even if there is a lot of this white fungus growth, also known as mycelium, it is innocuous. (1)
Yellow fungal mold
Another example of benign saprophytic fungus is yellow mold growth on plant soil. Scrape it off or repot the plant in sterile potting soil to get rid of it.
Gray mold on houseplant soil
Gray mold can occasionally be a fungus called Botrytis. The location of this fuzzy growth is typically close to the soil’s surface or growing in thick vegetation. If gray mold is not handled, the plant could suffer.
Sooty mold
Scale may be indicated by patches of black or dark green material that resemble soot. As they consume the plant’s sap, these minuscule insects have the ability to kill your plant. Although the sooty mold won’t hurt the plant, you must promptly get rid of scale insects.
Powdery mildew
Powdery mildew, a fungus that affects houseplants, can have the appearance of flour dusted on plants. The plant’s photosynthesis may be hampered if the fungal infestation becomes too severe, which could restrict the plant’s growth.
What’s causing my succulents to mold?
It’s possible for mold to form on your succulent plants frequently. It will be helpful to understand how the mold develops on your plant before we talk about how to treat it.
Over-Watering
Anywhere there is moisture in the air, mold can grow. Spores, which can float through the air and land on surfaces, are the source of mold growth. Mold spores are actually present all around us. To begin growing, the spores simply require the ideal habitat. Overwatering your plant increases the moisture that spores have access to.
Overwatering can harm your plants and is a common cause of home plant death. The plant cannot properly absorb oxygen when the soil is excessively wet.
In a few ways, watering succulents differs from watering standard houseplants. Succulents have bigger leaves and larger roots and stalks. As a result, they can store more water and survive longer without freshwater. Because of this, they resemble cacti greatly and are excellent indoor plants for individuals who are busy.
You’ll be safe watering your plant once a week during the summer and warmer months. It goes without saying that you should exercise caution, but weekly watering will be sufficient for your succulent to survive. Fill the pot to the brim with water before watering. The succulent will be able to absorb all the water it requires this way. You can also combine fertilizer and water if your succulent is still growing.
You can water your succulent less regularly in the winter than you can in the summer. Don’t worry if the soil gets a little dry; the plant will still be able to live.
Mold growth will be more challenging if you adhere to the succulent’s recommended watering schedule. However, even if you water once each week, mold might still develop. Let’s examine some additional causes of fungus that you might be experiencing.
Not Enough Sunlight
Lack of sunshine is another frequent factor that can contribute to the growth of mold. Much light is required by succulents. They may be exposed to up to six hours of sunshine when they are outside. If you have an indoor succulent, you must put it in the area of your house with the best lighting to make sure it receives adequate light. Mold is more likely to start growing if the plant is not given enough to eat.
Poor Maintenance
If you do not properly care for your plant, mold will develop. Since they don’t need much upkeep, succulents are relatively simple to look after, but you still need to invest some time and effort into it. Neglecting a plant will foster the ideal conditions for the growth of fungus. This covers insufficient cleaning, inadequate illumination, and inappropriate watering.
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.
How come my soil grows mold?
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.
What Is White Mold?
Over 360 different plants, including beans, peas, lettuce, and members of the cabbage family, are susceptible to white mold, also known as sclerotinia. When it affects tomatoes, white mold is also known as wood rot. On blooms, stems, leaves, and pods with water-soaked areas, mold signs might be seen. Pods could rot, and leaves would droop, yellow, and die.
During flowering, host crops are most vulnerable, although immature seedlings are also quite weak. White mold often infects plants in the early spring or summer and then grows slowly for a while before becoming noticeable. When it’s cool outside, the white mold fungus releases spores that can spread to other plants by being carried by the wind. Destroying affected plants as soon as possible is crucial in order to prevent the spread of white mold.
How to Identify White Mold Damage
Here are some typical white mold symptoms, though they might vary based on the location and plant type:
- At first glance, the stem could seem to have a wet area. The plant will appear healthy from the top at this stage of the infection.
- Individual stems are wilting, especially at the base where there is a tan discolouration.
- There may be tan to dark brown blemishes on infected stems. Under situations of excessive humidity, a dense, cotton-like growth will develop from these wounds.
The Ohio State University provided the image. White mold’s dense, cotton-like growth completely consumes a bean plant.
How to Control White Mold
- If you come across any sick plants, get rid of them right away.
- Infected soil should be removed as much as possible and cleaned soil should be added in its place.
- To stop the disease from spreading, cover the affected ground with a barrier like plastic or mulch.
Prevent White Mold
- To prevent crowding, use well-drained soil and space your plants appropriately. Don’t forget to stay away from places with inadequate airflow.
- Try to avoid soaking the tops of your plants when you water them. Alternately, water the plants in the morning to give them time to dry out before dusk.
- To assist prevent infection, you can also spray your plants with a fungicide that has been approved. Just before the plants bud, spray them, and then sprinkle them once more a week later.
- Get rid of the weeds. This disease can be carried by weeds and spread to your plants.
- After harvesting, if at all feasible, eliminate all crop leftovers. This disease might manifest itself there if residue is left. Given the chance, white mold spores will survive the winter since they are long-lasting.
How does a succulent that has been overwatered look?
How can you tell if your succulent is getting too much water? You can usually determine if a succulent is being overwatered or underwatered by looking for telltale indications. A plant that has received too much water will have soft, mushy leaves.
The leaves would either turn translucent in color or appear lighter than they would on a healthy plant. A succulent that had received too much water would frequently lose leaves readily, even when only lightly handled. Usually, the lowest leaves are the ones to suffer first.
The plant will look to be unhealthy overall. When this occurs, the plant is either being overwatered, sitting in the incorrect soil that does not dry out quickly enough, or both.
Your plants are being overwatered if you have been giving them regular waterings or if you have been following a watering schedule regardless of how the plant appears.
On the other hand, a succulent that has been submerged will have withered, wrinkled, and deflated-looking leaves. The leaves will appear thin and flat. The entire plant will appear withered and dry.
The leaves of a good succulent plant should be thick and solid, not mushy or desiccated.
To learn more about this subject, visit my post titled “How To Tell If Your Succulent is Over or Under Watered,” in which I go into great length about how you may determine whether your succulent plant is being over or under watered.
This String of Pearls ‘Senecio Rowleyanus’ plant leaf is one that has been overwatered. If a succulent’s water storage capacity has been exceeded, it may physically burst from overwatering.
How can fungus appear on succulents?
Fungi belonging to the genus Colletotrichum produce anthracnose. Numerous types of succulents and cacti are impacted by this virus. Moist, tan-colored rot with red, orange, or pink pustules on the surface is an indication of anthracnose. Spots disappear quite rapidly from crowns and leaves. You can only remove and destroy afflicted leaves from your succulent when it has this fungus infected it. You should avoid recycling the soil and make sure that your instruments are completely clean because this virus spreads through contaminated pots and dirt. In order to eliminate any remaining fungal bodies, you should also use a copper fungicide.
Should I discard potting soil that has gone bad?
It is safe to use moldy potting soil because the majority of the mold that grows on its surface is a benign fungus. You can try to get the mold out of the potting soil if it has grown in large amounts. The potting mix should only be thrown away as a last option.
Contrary to popular opinion, moldy potting soil is not a serious problem. Whatever suits you best, you can decide to ignore it and keep using the potting soil you currently have, treat it for mold, or discard the entire package and start over. Let’s discuss several approaches of removing mold from your potting mix.
Is soil’s white mold harmful?
A white mold that appears on the potting soil for indoor plants is typically a saprophytic fungus that is not harmful. The fungus looks ugly and suggests that there is a problem even though it doesn’t harm the plant.
