It is essential to determine the issue and implement the necessary adjustments or treatments as soon as you can.

The most frequent cause for Haworthia becoming brown are sunburn or fungal illnesses. Root rot and underwatering caused by overwatering could be another reason. Burning of fertilizers and a lack of nutrition could also be the possible cause for Haworthia leaves becoming brown.

Haworthia becoming brown is usually in a sign that your plant may be experiencing certain stresses. Ill go over the various causes and assist you in fixing the issues as well.

Leaf Burn and Drying Out

Sunburn is the main reason for brown Haworthia leaves. These might see on other plants as well. Haworthia could develop brown patches on their leaves following moving to a more sun-filled area or during the recent heatwave.

Although burnt leaves can be ugly, they dont cause harm for the plants. It may take a while to heal the burns and the leaves will fall off as new growth begins to appear. Sunburn is more frequent in younger plants as opposed to mature plants.

How not to Burn Haworthia

When the Haworthia plants start to burn, move them or give them some shade.

To prepare your plant to receive direct sunlight slowly increase the amount of sunlight it gets over a duration of.

In the course of a long heatwave, even mature plants that are used to full sun can suffer from sunburn.

If you are expecting a heatwave move your Haworthia or shade it. It is important to keep your young or repotted Haworthia from direct sunlight or parts of the plant which are growing. If theyre unprotected from the sun, they could be burned.

While other causes can cause darkening of the leaves in succulents, the main reason for dark brown foliage on Haworthia is sun damage.

Although the majority are simple to handle There are some that require more effort.

Fungal Diseases Cause Brown Leaves on Haworthia

Haworthias are more susceptible to fungus-related diseases than other indoor plants, mostly due to its leaves hold water for longer periods of time.

If you alter the way the watering of your haworthia plant, itll be more susceptible to fungi.

The most common fungal illnesses that affect plants, southern blight and rust are among the most prevalent.

Powdery Mildew

The mildew appears as dusty small flecks or patches of white or light grey. Normal mildews are round and soft, with a tiny rise. If you notice the specific dots that are on the top of leaves, then take it as an indication of danger.

The growth of mildew in plants can appear to be coated with sugar powder or sifted through flour.

The affected leaves slowly change color, turning yellow, and eventually turn brown. Powdery mildew is simple to identify in all its varieties once you are aware of it.

Powdery mildew is not the only thing that kills Haworthia! It doesnt mean that you shouldnt ignore it. A few tiny spots will not harm the host plant initially However, they could propagate seeds to other plants or even remain in the soil of your garden.

The fungus feeds off the plants nutrients, thwarting the growth of the plant and reducing its yields.

It could stop photosynthesis if powdery mildew covers your Haworthia leaves. Similar to starving your plant in a gradual manner. Stressed Haworthias are more prone to various diseases and insects.


  • Cut off diseased leaves If mildew with powdery appearance is detected in the early stages, cutting off some of the affected leaves will generally stop or significantly slow the development of the disease.
  • Neem Oil Spray: It is believed to impede the spread of powdery mildew however, it isnt able to completely remove it completely. Make sure to dilute the neem oil prior to use. Since it is an oil, you need to include dishwashing soap, or Castile soap to mix evenly.
  • Copper Fungicide Copper-based fungicides can aid in fighting powdery mildew. If you notice that your Haworthia has been affected, apply fungicides right away and repeat the process every 7-10 days.
  • Sulfur: To control powdery mildew sulfur is a well-known fungicide, however it should be applied before symptoms begin to manifest. It can be sprayed onto susceptible plants to prevent infection.
  • Baking soda: If you mix liquid soap with the water you use, baking soda could be a powerful powdery mildew treatment. It can be used to prevent the spread of mildew instead of a treatment. Mix one cup of baking soda 1 teaspoon non-detergent liquid soap, 1-gallon of water, and then spray it on your Haworthia.


The fungal illness that causes damage to a range of plants, including succulents such as Haworthia. The plants that are affected are usually mature in the natural world.

There are white spots that are raised under the leaves or on the Haworthia stems. As the disease progresses the white spots will turn to black, then orange-brown.

Southern Blight

It is commonly called southern wilt, also known as Southern root rot. It is caused by the fungal genus Sclerotium Rolfsii is the cause of the development of. If your Haworthia suffers from southern blight, itll be dry and brown patches on it.

If untreated If left untreated, the leaves will turn yellow, and then turn light brown. It could be fatal to you Haworthia when it affects your root system.


The first thing you need to ensure sanitation. Keep the pot and the surrounding area clean will to prevent the spread of disease. Remove your Haworthia from other plants.

Since this is a soil-borne disease, it is essential to clean the soil using solar energy. The microwave oven is a reliable and fast method to sterilize the soil.

Botrytis blight

Botrytis blight is identified by brown dots appearing on buds and leaves, and flowers with black spots that are the most obvious early signs of the illness.

The leaves begin to rot as disease progresses as well as patches of, grayish mold develop in the affected regions.

Botrytis Blight is a fungal disease that causes symptoms that are caused by the disease and the fungus that causes it.

A mound of grayish dust-like fungal spores is formed over decaying and dead plant tissue. The spores can be easily seen.


Once it is active, botrytis blight is difficult to manage. It is imperative to act quickly to prevent any further harm.

The disease is typically spread to Haworthia through small wounds, and can spread quickly once it is first discovered.

The application of fungicides early can to prevent botrytis blight infections as well as reduce the spread of the disease.

Improper Watering

Since Haworthia is a type of succulentplant, it will not require a lot of water to thrive. It is best to water only when the soil layer on top feels dry. It is possible to for a while without watering yourHaworthia.

In certain instances, excessive watering could cause brown and mushy Haworthia leaves. The plant could be damaged all over, from the leaves to the root.

The brown patches are visible on Haworthia leaves after they have absorbed excessive amounts of water. This causes their cells to become saturated and break. The dark patches on the leaves could also be a sign that the plant has been submerged in water for too long.

The flecks in the middle on your Haworthia leaves usually indicate that the plant is overwatered. Browning around the edges of the leaves usually indicates that the plant is submerged.


To avoid this from happening, add water only after the top 1-2 inches of soil are completely dry.

Pay particular focus on soil moisture in the winter and fall months. Since Haworthia is not able to thrive in cold temperatures it requires less water to ensure its health. It is recommended to water less frequently in winter months than during the summer.

The watering of your plant regularly keeps it healthy. Be careful not to overwater it or your leaves could become yellow or even fall off completely. Over-watering can be harmful to the leaves.

Lack of Nutrition

Iron (Fe) and manganese are vital to the production of chlorophyll. If your Haworth is deficient in these nutrients , there will be less chlorophyll , and therefore less production of food.

The lack of chlorophyll can cause physical disorders such as chlorosis or the browning on the Haworthia leaves.

If none of the explanations above are applicable to you, your Haworthia might require additional nutrients. Insufficient nutrients cause Haworthia leaves to change color.

The addition of fertilizer can aid in fixing the issue. The three main nutrients, potassium, and nitrogen phosphorus are three of the most essential nutrients found in fertilizer. Each year, two to three applications are enough.

The Haworthia plant goes into hibernation during the winter months, and all the physiological processes are slowed down. This is why, during this time it is best to avoid the addition of any fertilizer of any kind.

In the summer and spring seasons start applying fertilizer at 8-10 weeks intervals. You can choose an alternative to delicious plant (amazon hyperlink) and then apply it by mixing with water.

Root Rot

Most often the leaves that are brown in Haworthia are the result of an infection caused by an excessive amount of moisture within the root.

Inadequate drainage and overwatering are the main root rot causes. Haworthia roots need to dry out between waterings to perform properly.

When you contract fungal illness, the leaves become dark, and then disappear. Take the pot off and look at the roots to determine whether there is root rot present.

Inadequate drainage or waterlogging are the main reasons for brown spots appearing in the leaf of Haworthia.

The problem could be made worse due to a lack of sunlight. A large pot could keep the roots of your plant moist between waterings, which can be beneficial.


  • If you are able to detect root rot in the early stages it can be treated. Since root rot is usually caused by drainage issues It is crucial to treat the issue promptly.
  • Use less water and an efficient draining container as well as fast-draining pots to ensure your plants flourish.
  • Then, you can determine the severity that the damages are. If the leaves of your Haworthia are merely brown spots on them There is no need to plant them again.
  • Give at minimum two weeks for the plant to completely dry out so that the roots can recover. Be sure that your Haworthia gets enough sun.
  • If youre not sure whether the Haworthias roots are damp or not, you can make use of a moisture gauge.
  • Additionally, if the damage is extensive or growing rapidly cutting and repotting is required to correct the issue.
  • Remove your plant from the container and provide it with a thorough wash with water. Get rid of any mushy roots that might have developed.
  • Replace the soil in the pot using an easy-draining garden soil like this. Keep watering properly to prevent any recurrence.

Edema or Oedema

The condition known as edema (oedema) is an issue that is often due to excessive water. If your Haworthia is drinking more water than it is able to handle, then leaves will develop black blisters, or crystal-like growth on the leaves. This happens in summertime because during this time, an the mistake of overwatering occurs.

It is crucial to keep in mind that this is not an bacterial or fungal disease. Therefore, your other plant isnt negatively affected.

The blisters become brown, and the leaves that are severely affected are susceptible to pests and diseases. The haworthias brown spots appear to be caused by thrips or spider mites.


Though mildly damaged haworthia may save itself from swelling, when it is severely affected it is better to remove the affected leaves in place. Since the brown spots on the plant wont heal, its not worth the time and effort to attempt to save it.

  • Here are some suggestions to control this Edema in Haworthia:
  • Select a soil that is well-drained and succulent.
  • Plant the pot in a bright and well-lit location.
  • As haworthia grows slowly, do not overfertilize it.
  • Keep a moderate level of humidity.

Low Humidity

In extreme low humidity plants lose more water via the process of transpiration. There wont be enough water available to keep the cells alive. If the leaves are losing excessive amounts of water, they will wilt and become brown.


You can check the level of humidity using an instrument for measuring humidity on Amazon. If youre living in a low humidity area then you must raise the humidity to a moderate amount of 50-60 percent.

Utilizing a pebble tray to boost humidity is simple to accomplish even if you dont have access to an humidifier.

Insect Infestation

Haworthias are famous for their ability to flourish without being harmed by insects. Spider mites and mealybugs are both possible, however they are extremely rare.

The sap-sucking insects cause leaves to change color to brown.


In the event that you find that your Howorthia is infested by spider mites or mealybugs, you can eliminate them by hand and spray the oil with neem mixing with water. Neem oil is great for the sap-sucking insects.

Fertilizer Burn

Over-fertilizing plants can cause haworthias to burn. Fertilizers are loaded with various salts that can dehydrate roots, a process known as Reverse Osmosis.

Reverse osmosis happens when the salt content of soil exceeds the plants salt levels which can cause chemical burns and dehydration.

The most severe damage happens at the root, in the area where dirt is. The salt in fertilizers can cause burning of roots and block the absorption of water. Plants that arent able to absorb water is likely to die!

Here are some indications that could be caused by the over-fertilization process:

  • An organic layer on over the surface of soil.
  • The tip of the leaf and occasionally edges may be burned.
  • Yellowing Leaves
  • The roots that are burned will darken.
  • Haworthia is expected to grow very slowly.


If youve noticed these symptoms, its likely youve over-fed your haworthia. However, you can correct this and heres the procedure:

Scrape the fertilizer excess off on the top of the soil. I suggest removing about 3 inches of dirt from above the plant. This will protect the plant from stress.

Then, you must take off the burnt or brown leaves as you will not be able to regenerate them.

Remove the fertilizer in the potting soil by giving it a the freshwater rinse.

Dont fertilize your plant within the next one month. Following this, your plant will recover over time.
