String of Hearts (Ceropegia woodii) succulent is one of the most popular and trendy houseplants due to its unique, captivating appearance, ease of care, and lovely trailing growth habit. Native to South Africa, this plant has long, slender vines that can extend several feet in length. Its leaves are small, elongated, and have a heart-shaped form, giving the plant its common name. The leaves have a grayish-green hue and often display lighter green or silver variegation patterns. They grow in pairs, opposite each other along the trailing stems, and are connected by delicate, thread-like stems, adding to the plants delicate and graceful appearance.
As a succulent, the String of Hearts has adapted to survive in dry conditions by storing water in its leaves and stems. This plant requires minimal upkeep and can thrive in most indoor environments. However, it does not mean that String of Hearts is trouble-free. Curling or wrinkled leaves is one of these succulents most common problems, and it usually is an indicator of several underlying issues. Here are some possible reasons for curling leaves and their corresponding solutions:
Insufficient watering is a frequent culprit behind leaf curling in succulents. If the leaves appear wrinkled or shriveled along with curling, it signifies that the plant needs more water. When a String of Hearts doesnt receive enough water, it responds by conserving moisture, which can lead to leaf curling. In addition to curling, an underwatered String of Hearts leaves may appear withered, shriveled, or wrinkled. This is a clear sign that the plant is hydrated.
To solve this problem, increase the frequency of watering sessions to provide the plant with sufficient moisture. The goal is to maintain a proper balance between hydration and allowing the soil to partially dry out between waterings. When watering, ensure that you thoroughly moisten the soil, allowing water to penetrate the root zone. Water until it drains out of the pots drainage holes, then remove any excess water from the saucer to prevent waterlogging.
It may sound strange, but too much water can also cause the leaves of String of Hearts to curl and wrinkle. The reason is that overwatering can saturate the soil, depriving the roots of necessary oxygen. This can lead to root suffocation, resulting in poor nutrient uptake and overall plant stress. Moreover, excessive moisture in the soil can cause the roots to become waterlogged, preventing them from absorbing water properly. As a result, the leaves may curl as a response to stress.
The solution to this is to move the pot to an airy spot with good airflow and allow the soil to dry. Check for signs of root rot or root damage and repot if necessary with well-draining soil in a porous pot with drainage holes. Don’t forget that good drainage is crucial for succulents, so make sure there is no excess water retained in the pot. Water only when the topsoil is dry to the touch and empty the saucer to prevent the plant from sitting in water.
Check for signs of root rot or root damage and repot if necessary with well-draining soil in a porous pot with drainage holes.
Proper lighting is very important to String of Hearts. This plant requires an adequate amount of light to carry out photosynthesis and maintain its overall health. Without enough lighting, its ability to produce energy is impaired, which can lead to leaf curling. The leaves can also elongate as the plant tries to reach for more light. The foliage may appear pale or stretched as well.
The solution is to immediately move your String of Hearts to a location where it can receive a lot of bright, indirect light. Ideally, place it near a north or east-facing window where it can get several hours of gentle morning or afternoon sunlight. If natural light is limited, you can also invest in a grow lamp. To ensure even growth and prevent the plant from leaning towards one side, periodically rotate the pot. This will allow all sides of the plant to receive equal exposure to light.
With their striking rosette shapes and succulent foliage, aeoniums are eye-catching additions to any garden. However, you may notice your aeonium plant’s leaves starting to curl under, giving your plant an unsightly drooping appearance. What causes aeonium leaves to curl, and how can you fix it? Read on to unravel the mystery.
What is Aeonium?
Aeoniums are a genus of around 35 succulent plant species native to the Canary Islands, Madeira, and parts of Africa. They get their name from the whorl or “aeonium” leaf arrangement forming a circular rosette shape. There are a diverse range of aeonium varieties featuring different colored foliage like green, burgundy red, cream variegation and more.
Aeoniums are prized for being low maintenance, drought tolerant, and bringing unique visual interest to gardens. However, curled leaves are a sign your aeonium is stressed and in need of your care and attention.
Common Reasons for Aeonium Leaf Curling
There are several potential causes of aeonium leaves curling or becoming distorted, Here are some of the most likely culprits
-
Underwatering – Aeoniums can withstand dry conditions but need occasional deep watering. Leaves will curl inward if the plant is severely dehydrated.
-
Overwatering – Excess moisture leads to root rot and fungal issues Curling leaves try to prevent further water loss
-
Excess sunlight – Direct hot sun can scorch aeonium leaves. Curling creates protective shade. Moving plants to dappled sunlight prevents issues.
-
Temperature stress – Extreme heat or cold triggers leaf curling as the plant tries to limit exposure and conserve resources. Maintain optimal growing temperatures.
-
Pests – Insects like mealybugs, aphids and mites inflict damage while extracting plant fluids, causing curling leaves. Apply appropriate organic pest control measures.
-
Diseases – Fungal diseases prompt leaf curling. Isolate affected plants and improve air circulation and drainage.
-
Nutrient deficiencies – Lack of vital nutrients can interrupt proper growth, leading to distorted curled leaves. Apply a balanced liquid fertilizer.
-
Rootbound conditions – Aeoniums in too small a pot with intertwined roots suffer leaf curling Transplant to a larger container.
-
Poor air circulation – Stagnant air encourages fungal disease growth and leaf curling. Improve airflow around plants.
-
Incorrect pruning – Damaging the growing tip while pruning causes growth disturbance and leaf curling. Always prune correctly.
-
Sunburn – Similar to temperature stress, too much harsh sun exposure can burn aeonium leaves, making them shrivel and curl. Filter sunlight if needed.
Correcting Curled Aeonium Leaves
If your aeonium plant’s leaves begin curling inward or downwards, take prompt action to diagnose and remedy the problem:
-
Examine the plant and roots to determine likely causes like pests, disease, underwatering or other stress factors.
-
Increase watering frequency if dry soil is the issue but avoid overwatering which causes similar leaf curling.
-
Apply organic neem oil or insecticidal soap if pests are detected on the leaves or stems.
-
Move the plant to a location with more filtered sunlight if sunburn appears to be the culprit.
-
Transplant rootbound specimens into larger containers to allow room for additional growth.
-
Apply seaweed extract or compost tea to provide beneficial nutrients if deficiency is suspected.
-
Remove and isolate diseased plants showing signs of fungus or rot and improve drainage and air flow.
-
Prune only as needed, avoiding harming the central growth tip to prevent damaging leaf curling.
-
Monitor the plant closely over subsequent weeks for signs of improving health and less leaf curling.
Preventing Future Aeonium Leaf Curling
Once you’ve corrected existing leaf curling problems in your aeonium plant, keep it happy and healthy through attentive care:
-
Water thoroughly only when the topsoil becomes dry, avoiding both under and overwatering.
-
Ensure the plant receives 4-6 hours of filtered sunlight or dappled shade daily.
-
Apply a dilute, balanced fertilizer occasionally during the active growing season.
-
Check frequently for pests like aphids or mites and treat with organic sprays if detected.
-
Prune dead leaves and spent flower stalks to improve plant appearance and air circulation.
-
Repot in fresh soil when the roots have filled out the container or become congested.
-
Shelter pots from harsh rainstorms, frost and freezing temperatures which can damage leaves.
-
Propagate new aeoniums from leaf cuttings for an attractive groundcover.
When to Worry About Curled Leaves
Occasional temporary leaf curling when an aeonium is stressed by intense sun or a missed watering isn’t necessarily worrisome if corrected promptly. However, take note if:
- Multiple leaves are curled,Plant leaves remain curled even after environmental adjustments,Leaf curling is accompanied by wilting, discoloration or leaf drop,The central rosette stem becomes curled or distorted,Leaf curling quickly returns after treatments or repotting.
These scenarios indicate a chronic underlying issue that needs diagnosis and resolution to restore plant vigor and prevent lasting damage or dieback. Don’t hesitate to enlist help from a horticultural specialist if the problem persists.
Common Aeonium Varieties Prone to Leaf Curling
While all aeoniums can potentially develop leaf curling, some varieties are more susceptible than others:

[High Temperature]High Temperature or Harsh Direct Sunlight
High temperatures and harsh, direct sunlight can contribute to leaf curling in String of Hearts. This plant thrives in moderate temperature ranges, and excessive heat and scorching sun can stress them. This stress can affect their overall health and cause leaves to curl as a protective mechanism. In high temperatures, plants tend to lose water more rapidly through a process called transpiration. This can result in dehydration and leaf curling as the plant tries to conserve moisture. Moreover, prolonged exposure to direct sunlight can result in sunburnt, curling leaves. Harsh direct also increase the temperature around the plant, again leading to heat stress.
To solve this problem, you should move your String of Heart to a shadier spot away from scorching direct sunlight with a milder temperature. You can use sheer curtains, blinds, or shade cloth to diffuse the sunlight and reduce heat exposure. Enhance air movement around the plant by using a fan or keeping windows open to improve ventilation. This can help dissipate heat and prevent excessive heat buildup. Aim to maintain a stable temperature within the ideal range between 65°F to 80°F.
[Low Humidity]Low Humidity or Dry Air
Low humidity can contribute to leaf curling in String of Hearts succulents. These plants thrive in moderate to high-humidity environments (40-50% humidity level), and when the air becomes too dry, they can experience moisture loss, leading to leaf curling. Prolonged exposure to low humidity can hinder the plants growth and overall health. It may affect the plants ability to take up water and nutrients, leading to leaf curling and stunted growth.
To solve the low humidity issue, you can create a more humid environment around the plant by misting the leaves with water using a spray bottle. This helps to increase the humidity directly around the plant. You can also place a tray or saucer filled with water and pebbles near the plant. As the water evaporates, it increases the humidity around the plant. Ensure that the pot is not sitting directly in the water to prevent waterlogging. Alternatively, cluster your String of Hearts with other houseplants to create a microclimate with slightly higher humidity, or simply use a humidifier in the room where the plant is located.
