Common Causes of Bumps on Succulent Leaves
There are a few common causes of bumps on succulent leaves that can affect the health and appearance of your plant. These include:
Plant pests
Succulent plants are susceptible to a variety of pests, including aphids, mealybugs, and scale insects. These pests can cause bumps or abnormalities on the leaves of your plant as they feed on the sap and nutrients. Pest infestations can also cause yellowing or wilting of the leaves and a sticky residue on the plant.
Diseases
Succulent plants can also be affected by a variety of diseases, including fungal infections and bacterial infections. These diseases can cause bumps, spots, or discoloration on the leaves of your plant, as well as other symptoms such as yellowing, wilting, or rot.
Environmental stress
Bumps on succulent leaves can also be caused by environmental stress, such as improper watering, inadequate light, or extreme temperature fluctuations. These factors can cause the plant to become stressed and result in abnormal growth or changes in the leaves.
Overwatering
Overwatering provides excess moisture to the succulent’s roots, allowing more water to be taken up by the cells than can be properly processed. This over-absorption of water causes the cells to swell and enlarge, building up fluid pressure against the cell walls. When this pressure exceeds the tensile strength of the cell walls, they rupture and burst outward, forming blisters full of fluid called edema on the surface of leaves and stems.

Treatment Options for Bumps on Succulent Leaves
The treatment option for bumps on succulent leaves will depend on the underlying cause. Here are a few options to consider:
Pest infestations
If the bumps on your succulent leaves are caused by plant pests, the first step is to remove any visible pests from the plant using a cotton swab or a soft cloth. You can also use a pesticide or natural pest control methods, such as neem oil or horticultural soap, to help eliminate the pests. Be sure to follow the instructions on the product label and take care to avoid overspraying or overapplying the treatment.
Diseases
If the bumps on your succulent leaves are caused by a fungal or bacterial infection, it is important to remove any infected leaves or stems to prevent the spread of the disease. You can also use a fungicide or bactericide to help eliminate the infection. Be sure to follow the instructions on the product label and take care to avoid overspraying or overapplying the treatment.
Environmental stress
If the bumps on your succulent leaves are caused by environmental stress, the first step is to address the underlying issue. This may involve adjusting the watering schedule, providing the succulent with adequate light, or taking steps to protect the succulent from extreme temperature fluctuations.

Prevention Tips for Bumps on Succulent Leaves
To prevent the bad kind of bumps on succulent leaves, it is important to follow proper care guidelines and take steps to protect your succulent from pests, diseases, and environmental stress. Here are a few tips to consider:
Water properly
Succulent succulents require well-draining soil and infrequent watering to thrive. Overwatering can lead to root rot and other problems, while underwatering can cause the leaves to become dry and brittle. Be sure to follow the specific care guidelines for your particular species of succulent and pay attention to the moisture levels in the soil to ensure your succulent is getting the proper amount of water.
Provide adequate light
Succulent plants require plenty of sunlight to thrive. Be sure to place your succulent in a location that receives at least six hours of direct sunlight per day. If you are growing your succulent indoors, use a grow light to provide the necessary light.
Protect from extreme temperature fluctuations
Succulent plants can be sensitive to extreme temperature fluctuations, especially if they are not acclimated to the new conditions. Be sure to protect your succulent from drafts, heaters, and air conditioning vents, and avoid placing it in a location that experiences significant temperature changes.
Regularly inspect for pests and diseases
It is important to regularly inspect your succulent succulent for signs of pests or diseases, such as bumps on the leaves or other abnormalities. If you notice any issues, take steps to address the problem as soon as possible to prevent it from worsening.
Use a high-quality potting mix
Succulent plants require a well-draining potting mix that is specifically formulated for succulents. Be sure to use a high-quality potting mix to ensure your succulent has the proper nutrients and drainage it needs to thrive.

Not All Bumps Are Created Equal – All About Caruncles
Caruncles are small, bump-like structures that can be found on the leaves of some succulents. Caruncles are typically found on succulents in the Crassulaceae family, which includes popular succulent plants such as Echeveria ‘Raindrops’, Echeveria ‘Etna’ and other Echeveria species. They are thought to serve a variety of functions, including helping to anchor the leaf to the stem, protecting the succulent against herbivores, and storing water.

Caruncles are usually small, ranging in size from a few millimeters to a few centimeters, and are typically the same color as the succulent. They can be smooth or rough, and some species of succulents have more prominent caruncles than others.
If you are concerned about the presence of caruncles on your succulent plant, it is important to remember that they are a natural part of the plant’s anatomy and do not usually cause any harm.
