Sun scalding, also known as succulent sunburn, results in a patch or huge burned regions. That damage is irreversible and cannot be repaired. The succulent (or cactus) can be in direct light after being indoors for a few months, although this is a common mistake made when moving plants from indoors to outdoors. It’s comparable to exposing your skin to the sun without protection. At that point, you should temporarily provide your plant with morning sun or indirect light to help it acclimate.
Insects like scale, which have brown spots on them, can also be treated with a cotton swab dipped in rubbing alcohol. Simply rub the scale insects off the plant using a brush.
Brown spots are a result of fungal decay. These typically result from an adverse side effect of over watering, which causes edema, or water retention, in the plant tissue. Pockmarks are brought on by cells exploding.
Why do the brown stains on my succulent exist?
Sunburn or sun damage is the most frequent cause of brown leaves on succulent plants. When you observe brown spots on your plants’ leaves after moving them to a bright place or after a heatwave or other period of extreme heat, these patches are the equivalent of sunburn.
Brown spots from sunburn do not actually injure the plant, but they do leave a permanent mark on the leaves, which is unsightly but not harmful. The leaves will ultimately fall off as new growth appears, but these spots won’t fade away. More sensitive to sunlight than mature plants are little baby plants or newly produced plants.
If you notice that the plant is getting burnt, move it to a more shaded area or give it some shade. If you intend to leave your plant in a position that receives direct sunlight all day, acclimate it to the heat by gradually increasing its sun exposure. Remember that during a severe heatwave, even a mature plant that has become accustomed to full sun might still get burnt.
When a severe heatwave is predicted, move the plant or offer shade to avoid this from happening. Never leave young plants, plants without roots, or leaves that you are propagating outside in the direct light. Always give protection from the sun to prevent them from becoming completely cooked.
While solar damage is the most frequent cause of dark leaves on succulent plants, there are generally additional factors at play. While the majority of them may be resolved quickly and easily, some are trickier to resolve than others.
Why do the spots appear on my succulent?
Dead cells are what cause the brown patches on succulents. Numerous environmental conditions, such as high humidity, excessive watering, and a lack of sunshine, contribute to their development.
The brown frequently appears when your plant is deficient in calcium or phosphorus as well.
The most frequent causes are:
Natural Aging
As the leaves deteriorate and die after several years of ownership, certain brown patches may naturally appear on your plant.
Browning like this is common. Your succulents will continue to appear healthy if you simply remove any leaves that are brown or withering when you discover them.
Environmental Damage
Browning may happen if your plant is subjected to extremely cold or hot weather.
Brown spots are probably the result of environmental harm if you reside in a region with icy winters and sweltering summers.
Brown spots may form during the winter due to too much cold, whereas brown spots may appear during the summer due to too much heat.
Chemical Damage
If brown patches start to emerge on succulents after you’ve used chemicals on your plants, such pesticides or fertilizers, chemical damage may be the cause.
It’s likely that a pesticide was sprayed on the leaves and caused browning if you detect brown leaf tips and margins around the base of the leaves.
Edema
These brown areas may also contain liquid or water inside the tissue of the succulent leaf, giving them a bloated and droopy appearance.
Edema frequently develops when your plant isn’t receiving enough water to drink; this could be due to either under- or overwatering.
Fungal Disease
This fungus-causing brown patch appears to be cottony mold developing on the leaves, stems, or buds of your plant.
With this particular form of brown spotting issue, browning of the flesh is also possible; in older growth regions, such as those near the center of the rosette, it may resemble brown marbling.
Excess Sunlight and Heat
If sunburned sections of succulents develop brown blotches, your plant is probably receiving too much heat or sunlight.
If you reside somewhere with extremely hot summers and little to no shade to shield your plants from the sun’s direct rays, these brownings may also happen.
Excess Salt Damage (Coastal Areas)
Succulents can develop brown patches on their leaves if their leaves are exposed to too much salt if you live near the ocean or other saltwater bodies like lakes or rivers.
Your plant may appear wilted and dry if it is continuously developing dark spots on its leaves from salt.
Poor Soil Quality (Excess Salts)
Poor soil conditions can cause brown patches on succulents. If this happens, your plant may be receiving too much fertilizer or other nutrients, such as salts that accumulate over time when water evaporates back into the atmosphere.
Fluoride Toxicity
If brown patches start to emerge between the leaves of succulent plants, this could be a sign of fluoride toxicity from water that contains a lot of minerals and salts.
If your plant develops brown patches that resemble brown lines or streaks when they divide the leaf into sections, this is a sign of fluoride toxicity-related browning.
Insect Bites
It may indicate insect damage if dark stains on succulents resemble tooth marks or tiny holes.
When brown spots emerge where insects have been draining the juice out of the plant’s tissues, mealybugs and aphids are frequently to blame.
Drought Stress
If the brown spots on succulents are the result of drought stress, particularly if you first see the spots on the oldest leaves.
When it’s too hot or cold for your plant to effectively hydrate itself through their roots, browning from drought happens.
Sudden Temperature Changes
A sudden temperature shift may be the cause of a brown spot on succulents that initially appears light before turning brown.
This kind of browning may result from a sudden, abrupt rise or fall in temperature because it alters the fluid within your leaves.
Abiotic Disorders
Succulents can develop abiotic brown spots that brown quickly but are not communicable, unlike other browning issues brought on by insects or viruses.
The youngest leaves are typically the first to be affected by this sort of browning before it progressively spreads to older leaves and stems.
It frequently has irregular brown spots that are brownish-yellow around the browning areas and is brownish-white in appearance.
Root Rot
Brown spots on succulents can also be a sign of root rot, which initially browns leaves and stems quickly before spreading in a zigzag pattern to older plants.
Brownish-white or brown specks may have yellow haloes surrounding them.

You may provide your plants sufficient air circulation and make it easier for the soil to dry out by removing these dried leaves from beneath your plants. Removing these dried leaves will assist avoid the growth of rot, mildew, and/or illnesses, especially in humid or very rainy weather. Additionally, air circulation around the plant’s base is made possible by this procedure.
Less Pests
Succulents are susceptible to a wide range of pest attacks, just like most other plants. Getting rid of the dead leaves beneath your plant can also help deter pests. Little insects adore wet areas where they may hide and reproduce. A succulent’s compressed lower leaves are likely to retain moisture around the plant’s base, which will attract pests. Your plant has a higher chance of repelling these pests if you remove these leaves.
Another alluring nesting habitat for bugs, specifically aphids, can be bloom stalks. If you see that your blooms are starting to develop this bug problem, you can either completely remove the bloom stalk or treat the bloom with a mix of diluted rubbing alcohol and water. These bugs frequently spread disease to surrounding plants and flowers if the situation is left untreated. In order to remove bloom stalks from your plant, either gently wriggle the stalk back and forth or, if it hasn’t dried up yet, snap or cut it low.

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.
