Succulents are plants with leaves, stems, and roots that can store water. This means that succulents can grow where other plants would die from a lack of water. But sometimes, succulents can get mold. Seeing mold on your succulents may wonder, “Why does my succulent have mold?” Succulents can get a mold for several reasons, but most are nothing to worry about. This blog post will talk about the most common reasons why succulents get mold and how to fix the problem. Read on to find out more!

Why does my succulent have mold?

Succulents are plants that can store water in their leaves and stems. When the weather is hot, the succulent can’t cool down like other plants, so it takes longer for the water to evaporate. This can lead to a build-up of water and salts inside the plant. Over time, this can cause mold to form.

One of the most common causes of mold on succulents is a fungus. This fungus lives on the surface of succulents and feeds off of them. As succulents get older, they may show signs of fungal infection, including mold. If you notice your succulent has mold and you can’t identify the source, it’s best to take it to a plant expert for diagnosis. But in most cases, removing the mold from your succulent won’t harm you and will likely help restore your plant’s health.

Poor Air Circulation

If your succulent has mold, it may be because the plant doesn’t have enough air circulation. Poor air circulation can be a cause of succulent mold. If the succulent is not getting enough oxygen, it will start to grow mold. Succulents are often placed in low-light areas, so they may not get enough sunlight to help them grow properly.

Contaminated Soil

There are a few potential reasons why a succulent might have mold growing. One possibility is that the succulent grows in soil contaminated with harmful fungi or bacteria. If this is the case, the mold may be a symptom of the underlying problem rather than its cause. Alternatively, the succulent could be experiencing some environmental issues, such as low humidity or too much sunlight. If you notice mold on your succulents, it’s important to take steps to address the underlying issue before attempting to get rid of the mold itself.

Poor Drainage/Over-Watering

If your succulent has mold, it may be due to poor drainage or overwatering. The succulent will not be able to take in enough water and will thus rot. Ensure your succulent has good drainage and only water when the soil is completely dry to prevent this. Additionally, make sure your succulent is not over-watered. Succulents need water to survive, but too much water can cause them to rot.

Not Enough Sunlight

If the succulent is not getting enough sunlight, it can result in mold. Succulents need bright light to grow properly. If they are not receiving the necessary amount of sunlight, the leaves will curl and produce mold. Additionally, succulents like to be kept moist, so they can also develop mold if they are not getting enough water.

If you notice mold on your succulents, it’s important to take steps to address the underlying issue before attempting to get rid of the mold itself.

Poor Maintenance

Poor maintenance is the most common cause of succulent mold. Succulents require lots of water, but they also need air to breathe. If the soil around the succulent is wet, it can keep the plant from getting enough air, leading to problems like succulent mold.

Another problem with succulent plants is that they often colonize other plants. When a succulent touch another plant, its leaves can spread spores. If there’s a fungus growing on those spores, it can also start growing on other plants. So if you have a collection of succulents, keep them separate so that any problems with one aren’t spread to others in your garden.

Not getting enough nutrients

Mold can signify that your succulent is not getting the nutrients it needs. Suppose you are noticing mold on your succulent. In that case, it might be a good idea to check the soil around the plant and see if there are any signs of fertilizer poisoning. Succulents like fertilizers are high in nitrogen, phosphorus, and potassium. If you’re not sure what kind of fertilizer your succulent is getting, ask a gardening expert or search online for information on specific succulent fertilizers.

If you don’t think your succulent is getting the nutrients it needs, you can do a few things to help. One option is to add more organic matter to the soil around the plant. This can include compost, shredded leaves, or rotten wood. Another option is to use a fertilizer that is specifically designed for succulents. Some of these fertilizers are available at garden stores or online.

Decomposing Leaves on Surface

If you notice mold growing on the surface of your succulent, there is a good chance that it’s due to decomposing leaves. When the leaves die and rot, this process releases nutrients and water into the soil. This moisture attracts bugs and other organisms that help the leaves decompose. Over time, this process can cause your succulents to become covered in mold. Suppose you’re worried about this happening to your plant. You can try to prevent it by keeping the soil moist but not wet and cleaning off any mold growth occasionally.

Different Types of Mold

Molds are fungi that can be found almost anywhere. They can grow on living or dead plants, fruits, vegetables, and other organic materials. There are many different types of mold, and each one has a different appearance and affects plants in different ways.

The most common type of mold on succulents is white mold. This mold causes the leaves to become covered in a white powdery substance. The affected leaves will eventually die and fall off the plant.

Sooty mold is another type of mold that can affect succulents. This black mold appears as a thick black coating on the leaves. Sooty mold (Black mold) can cause the leaves to turn yellow and die.

Grey mold is another type of succulent fungus that can cause problems for your plants.

What Should I Do About the Mold?

If you notice mold growing on your succulent, you can do a few things to prevent it from spreading.

First, make sure the succulent is adequately watered and fertilized; neglecting either can lead to mold growth. If the mold is on a surface that is easily accessible, like a leaf or the pot’s surface, gently scrape it off with a blade or your fingernail. If the mold has colonized deep into the succulent’s tissue, you may need to remove it completely with a knife or scalpel.

Finally, if you notice any signs of infection (like redness or swelling), stop watering and fertilizing the succulent until the problem has been resolved. Succulents are very resilient plants and usually recover from mild cases of mold without any further intervention; if you notice more severe symptoms like browning or wilting, contact your local garden center for help.

How do I get rid of mold on my succulents?

Removing mold from a succulent is usually straightforward but can be time-consuming. One approach is to use a dampened cloth to clean off the plant’s surface. Make sure to clean around the leaves and stem edges where the mold often grows. After cleaning, dry the plant’s surface thoroughly before adding new soil or water.

Another approach is to pour boiling water over your succulents and wait 10 minutes. After 10 minutes, dunk your succulent in cold water to cool it down and shock it. This will kill any mold on the plant and repel other types of pests that might want to live on or near your succulent. Be careful not to overwater your plant after using this method – overwatering can cause root rot.

If the mold is on the soil, you’ll need to remove it. Succulent mold is often spread by water droplets that fall from the plant onto the soil. To clean up the soil:

  1. Fill a bucket with lukewarm water and add a handful of baking soda.
  2. Soak your succulent soil in the bucket for 30 minutes, then scrub with a brush.
  3. Pour out the water and replace the soil.
  4. Clean all surfaces where mold may have spread, including watering spouts and vents.
