How To Kill Fungus On Succulents

Early indications of this fungus include round, gray-brown spots on the surfaces of leaves and stems. As the infection worsens, these spots turn fuzzy with mold. It is the type of fungus that spreads when the weather starts to cool down and get damp, typically in the early Spring or Summer. It thrives in a moist, shaded area with poor airflow.

Dishwashing soap is one of the most used home-made fungicides in the early signs of a plant affected by grey mold. Just make sure it doesn’t contain bleach or greasers. The damaged regions of plants with severe grey mold infections must be removed. It’s best to refrain from watering from the top as well.

Leaf stains

Succulents can get fungal leaf spots indoors and outdoors, although they are not harmful. What makes it annoying is that when the fungus becomes too accustomed to your plant, the small area will enlarge and start to resemble a blotch, which will probably eventually kill your plant.

A succulent with Leaf Spots can be treated in a number of secure and practical ways. You can either spray your succulent with a moderate solution of bicarbonate of soda (baking soda), using 1/2 teaspoon per gallon of water, or you can use an all-purpose fungicide.

fungus wilt

Fusarium Wilt is a fungus that lives in the soil. It penetrates the plant through the roots and starts reproducing in the vascular tissues, obstructing the plant’s ability to absorb water, leading to severe stress, wilting, yellowing, and most likely, death.

Regrettably, there is currently no known cure for fusarium wilt in plants. The fastest removal and disposal of the infected plant is the best advised course of action for this fungus. Fusarium-contaminated soil must also be removed. This will aid in limiting the spread of the fungus.


A series of fungal infections known as anthracnose are brought on by members of the Colletotrichum genus. Circular, pale, sunken, or brownish patches that are characteristic of this type of fungus will cause the plant tissues to dry up and become hard like bark.

The only way to save your succulent once it has been attacked by this fungus is to remove the afflicted leaves. To further prevent the spread of this fungus, it is best to replace the contaminated plant’s soil and pot in addition to thoroughly cleaning all of your instruments.

You can apply fungicides that contain chlorothalonil, copper sprays with copper diammonia diacetate, propiconazole, and systemic fungicide thiophanate-methyl to eliminate any remaining fungal bodies and to maintain control.

Rotten Root and Crown

In comparison to other fungal illnesses, root and crown rots are among the hardest to diagnose. They don’t exhibit any distinctive symptoms that could enable you to identify an infection in your succulent.

To give you an example, a plant with root rot will first begin to wilt, then the leaves will start to turn brown, and finally the stems will start to rot, causing the plant to topple over. The roots will turn brown beneath the earth and will easily separate if the soil is carefully scraped away.

Fine feeder roots typically maintain a healthy white to tan color and can hold the root ball together effectively even if the root crown is also diseased. However, as soon as the plant’s soil is removed, brown spots can be seen on the cortex of the roots as well as the root crown or stem base.

Sadly, therapy does not work well for root and crown rot. However, this can be prevented by lowering moisture. Simply use a well-draining container and give your succulents the appropriate amount of water to achieve this. Just enough to meet the requirements of your plant. Additionally, any mulch that is longer than 4 inches should be removed to avoid letting your plant remain in excessively moist soil.

Why does succulent fungus develop?

Probably the easiest plants to grow are succulents. They do, however, experience issues much like the majority of plants do. Succulents exist in a wide variety of forms, hues, and dimensions, but they all have a tendency to get fungal diseases when taken out of their natural environments. Succulents are often adapted to a dry climate, hence the main cause of this is the shift in climate. They must learn how to deal with too much moisture.

Similar to succulents, fungus come in a variety of forms. Fungi on the surface are simple to identify and treat, but there are many other kinds of fungi that can cause interior rots and present far more challenging issues. Some fungus attacks are very challenging to neutralize.

How can I keep my moldy succulents alive?

Apply a fungicide after gently removing any infected leaves or stems that have started to show indications of damage in order to treat powdery mildew. Powdery mildew may be killed with fungicides using sulfur, neem oil, or triforine on healthy leaves, stems, and buds. As a precautionary step, spray the fungicide on neighboring plants as well. Baking soda and horticultural oil have been used successfully by some gardeners, although this remedy hasn’t received much research.

Why is the white fuzz growing on my succulent?

Let’s talk about the Mealybug, the bane of every succulent lover. We despise them. We hate them. We despise them. See what I mean? They are the worst people ever. Beautiful succulents can be destroyed by them in an instant when they appear out of nowhere. Mealybugs on your succulent typically appear as a white, cottony substance close to the new growth. On rosette-type plants, they can be found right in the center of the plant, on the stem, or at the base of the leaves. Even if there are no outward indications of them, mealybugs can sneak up on you, so it’s a good idea to periodically inspect your plants. Most of the time, your leaves will start to become twisted and deformed before you even detect the real bugs. This occurs when pests congregate close to your fresh growth.

If you don’t properly examine the entire plant, Mealybugs may occasionally be more difficult to notice. The leaves on a plant like this Aeonium tabuliforme grow so closely together that mealys are unable to pass through them. Instead of having a plant that is obviously malformed, the insects are skulking underneath, feeding on older leaves and recent growth close to the stem. Mealybugs can breed in this potentially hazardous environment, making it simpler for them to spread to neighbouring plants undetected.

The above-mentioned mealy conditions are tolerable, and plants like these will probably recover soon with some help. However, other times the plant may be so contaminated and broken that it is advisable to JUST KILL IT WITH FIRE! Not particularly, however you should remove it as soon as you can from your other succulents to prevent the infestation from spreading.

Natural fungicides: What are they?

Simple DIY fungicides can be prepared in a matter of minutes, as can more complex ones requiring a number of substances. Although I favor the simple methods, there are situations when you need to use a strong fungicide.

Powdery Mildew Fighter

For all gardeners, powdery mildew is a nightmare. It affects many different plants, including apples, roses, melon, zucchini, and pumpkin. It might be seen as a powdery, ashy covering on your plants’ leaves. In addition to being ugly, it eventually weakens and destroys plants.

The powdery mildew is effectively stopped by this homemade fungicide spray. Roses with black spots can also use it.


  • Baking soda, 4 tablespoons
  • mild soap, 1 teaspoon
  • a quart of water

After combining all the components, pour the mixture into a spray bottle. Spray the entire leaf from top to bottom with the disease, making sure the liquid is so thick it drips down the leaves. Spray the entire plant, not just the affected leaves, as the fungus may be hidden even if you cannot see it.

Tomato Fungicide

One of the plants that most of us enjoy growing is the tomato, however they are frequently prone to fungal diseases including early blight, late blight, leaf mold, fusarium wilt, and others. Here is a method for preventing the fungus that harm tomato plants.

  • single garlic bulb
  • Canola oil, 2 tablespoons
  • 4 scorpions
  • lemon juice from one

These components should be combined, then steeped in a bucket all night. The following day, strain the mixture to get rid of all the solids using a cheesecloth or screen.

In a spray bottle filled with one gallon of water, add 4 tablespoons of this mixture. When you notice the symptoms of a fungus disease, spray the top and bottom of the leaves.

Apple Cider Vinegar

Although it requires many treatments every few days, this straightforward ingredient has throughout the years saved a lot of my plants from various fungal infections.

To a gallon of water, simply add 4 teaspoons of apple cider vinegar. Spray this solution in the morning to prevent the foliage from being burned by the sun and acid.

Use this spray as a prophylactic measure every few weeks to treat scab, black spot, leaf spot, and mildew.


Horseradish is such a strong fungicide that I planted it specifically for that purpose. Combine:

  • Horseradish, 1 cup
  • Water, 16 ounces

Overnight soak Strain the mixture and mix it with 2 quarts of water in the morning. Give your plants a liberal spraying of this.


Another easy homemade fungicide is this one. With this spray, I’ve had good results on zucchinis, roses, and fruit trees. Combine:

  • Cornmeal, 1 cup
  • 5 water gallons


This miracle medication, which has been beneficial to people for generations, is also amazing in the garden. I’ve seen a variety of fungicide spray ratios, but after much trial and error, I’ve discovered that this one produces the greatest results for me.

  • one aspirin
  • 4 cups of liquid

Add the aspirin to the water after crushing it into a powder. In order to keep your plants healthy during the growing season, spray them liberally every two weeks. Additionally, this mixture works nicely when sprayed as a preventive every two weeks or so.

Painted Daisies

The dried leaves of the painted daisy are where pyrethrin is derived. It is a simple to grow plant that produces a strong fungicidal spray. Simply allow some flowers to dry before grinding them into a powder. Soak in 4 gallons of water for 24 hours.

Spray on plants after straining through cheesecloth to treat and prevent fungal problems on any kind of plant.

How can white fungus on plants be eliminated?

The easiest strategy to avoid mold and other problems is usually to grow disease-resistant plant kinds. If that is not an option, you can try any of these home cures to get rid of the white mold on your plants:

  • Utilize neem oil. A naturally occurring ingredient called neem oil functions as an efficient insecticide to help fight off unwanted pests like white mold. Every few days, liberally spray the diseased plant with a mixture of two tablespoons of organic neem oil and a half gallon of water until the mold is gone.
  • Utilize mouthwash. White mold can sometimes be successfully treated with mouthwash containing ethanol. Apply a solution of one part mouthwash to three parts water to the afflicted regions. Avoid being too saturated. While mouthwash is a successful treatment for white mold, overuse can damage young plant development and burn leaves.
  • 3. Apply vinegar. Vinegar is a tried-and-true approach for getting rid of mold and bothersome white patches on your plants. Spray the affected leaves and stems with a solution made of a quart of water and two tablespoons of apple cider vinegar. Repeat several times daily until all mold is eliminated.
  • 4. Use preventative medicine. Preventing the growth of mold in the first place is one of the greatest strategies to combat it. To treat your plant’s leaves and stems, use an organic fungicide or mix one tablespoon baking soda with one and a half tablespoons liquid dish soap in one gallon of water. Spray the mixture onto the plant liberally.

Why do succulents have mold on them?

The Sclerotinia stem rot, which primarily affects field crops, is known by the common term white mold. If your succulent has white mold, it is more likely that it has powdery mildew, a common and manageable houseplant disease. It can survive on the succulents’ fleshy leaves and stems.

Powdery Mildew

Similar to succulents, powdery mildew prefers warm, relatively dry environments. Succulents are the most commonly afflicted plant species because they share comparable environmental requirements with powdery mildew. Your infection may have the typical white powdery coating appearance. It can also appear gray with rounded yellow, brown, or black growths, though. Although the powdery mildew can develop in a single location, it typically spreads to your plant’s other leaves, stems, and buds.


Powdery mildew may initially appear to be unharmful. Your succulent could be able to tolerate the disease, which has a white, moldy appearance, and even prosper for a while. Deflated, damaged, or malformed leaves could be seen as the illness progresses and worsens. The stems and leaves may also change from a light green to a golden color. Your succulent can lose leaves, stop flowering, or even pass away if it has a serious illness. When powdery mildew infects one of your plants, it might spread to others.


Apply a fungicide after gently removing any infected leaves or stems that have started to show indications of damage in order to treat powdery mildew. On healthy leaves, stems, and buds, powdery mildew may be efficiently eliminated by fungicides containing sulfur, neem oil, or triforine. As a precautionary step, spray the fungicide on neighboring plants as well. Some gardeners have had luck using a mixture of baking soda and horticultural oil.


If you can, keep your healthy plants separate from your sick plants. Next, make an effort to improve airflow to aid in slowing spore production. To do this, prune plants carefully, relocate them to windier areas, or use fans to circulate more air within your house. Spores need some humidity level, so switching to early morning watering can help slow or prevent powdery mildew spread.

How are DIY fungicides made?

You have control over the materials when you learn how to manufacture your own fungicide, many of which are already in your house. Here are some of the more widely used ingredients for creating fungicide for gardens and lawns:

  • In a gallon (4 L) of water, add 4 teaspoons or 1 heaping tablespoon (20 mL) of baking soda (Note: many resources recommend using potassium bicarbonate as a substitute for baking soda.).
  • For homemade plant fungicide, dishwashing soap is a common item that doesn’t contain bleach or degreaser.
  • To make homemade plant fungicide stick to leaves and stems, cooking oils are frequently added.
  • A common ingredient in commercial plant fungicides is pyrethrin, which is found in the leaves of the painted daisy flower. You may grow your own painted daisies and use the flowers to protect your plants from fungus. Flower heads should be dried before being ground or left to soak in 1/8 cup (29.5 mL) of alcohol overnight. Add up to 4 gallons (15 L) of water, combine, and then filter through cheesecloth.
  • Some bacterial and fungal illnesses can be controlled by using a Bordeaux combination during the dormant season. You can create your own Bordeaux mixture using copper sulfate powder and pulverized limestone. 4-4-50 is the suggested strength for application during dormancy. With 50 gallons (189 L) of water, combine 4 parts of each. Reduce the recipe for this homemade plant fungicide to 6.5 to 8 teaspoons (32–39 mL) of copper sulfate and 3 tablespoons (44 mL) of limestone to 1 pint (.5 L) of water if you only need a smaller amount, such as for a gallon.
