Uses
Aside from its ornamental value, the Stapelia juvencula Jacq. has some medicinal uses. The plant has been used by traditional healers in South Africa to treat various ailments such as indigestion, heartburn, and stomach ulcers. Some of the compounds found in the plant are believed to have antimicrobial and anti-inflammatory properties.
The plant is also known to attract flies because of its foul odor. However, this characteristic makes it useful as a natural insect repellent. In South Africa, the plant is sometimes used to keep flies away from homes and livestock.
Cultivation and maintenance
The Stapelia juvencula Jacq. is relatively easy to cultivate and maintain. It prefers well-drained soil, and it can tolerate a range of temperatures from 50 to 100 degrees Fahrenheit. It is a drought-tolerant plant and requires minimal watering. Overwatering can cause the plant to rot.
The plant can be propagated through stem cuttings, which should be left to dry for a few days before planting. The cuttings should be planted in a well-draining soil mixture and kept in a warm, sunny location until they start to sprout. The plant should be fertilized every two weeks during the growing season to encourage healthy growth and blooming.
Light Requirements
Stapelia juvencula requires bright but indirect sunlight to thrive. These plants should be placed in a location that receives several hours of bright but indirect light daily. They should be protected from direct sunlight, as it can scorch their leaves and cause irreparable damage.
Temperature Requirements
Stapelia juvencula prefers warm temperatures and cannot tolerate cold or frosty conditions. The ideal temperature range for these plants is between 60°F to 80°F (15°C to 27°C). They should be kept away from drafts and air conditioning units, which can cause the plant to become stressed and weak.
Soil Requirements
The soil for Stapelia juvencula should be well-draining and slightly acidic. A mix of equal parts of potting soil, sand, and perlite is suitable for these plants. They need good drainage to prevent root rot, so it is essential to ensure the pot has drainage holes at the bottom.
As these plants are succulent, they need soil that can retain moisture for a longer time. The addition of organic matter like peat moss or coconut coir can help retain moisture during drier periods.
Cultivation Methods
Stapelia juvencula Jacq. is a succulent plant species that can be cultivated both indoor and outdoor. It requires a well-draining potting mix and grows well in sandy soil or cactus soil enriched with organic matter. The plant prefers a warm and dry climate and does best in bright but indirect sunlight. If grown outside, it should be protected from frost and rain to avoid overwatering.
Watering Needs
The Stapelia juvencula Jacq. plant needs to be watered regularly during the growing season. However, the amount of water required should be minimal as overwatering can cause root rot. It is best to let the soil dry out between waterings and avoid watering in winter when the plant is dormant. When watered, pour gently at the base of the plant and do not allow water to touch the stem or leaves.
Fertilization
A balanced fertilizer can be applied to the Stapelia juvencula Jacq. plant during the growing season to encourage healthy growth. Fertilizing can be done once a month using a soluble fertilizer with a balanced mix of nitrogen, phosphorus, and potassium. The plant should not be fertilized when it is dormant, and overfertilization should be avoided.
Pruning
Pruning is not necessary for the Stapelia juvencula Jacq. plant; however, it can be done to remove dead or yellow leaves. The plant can also be pruned to control its size or shape. Use clean and sharp tools to avoid damaging the plant, and prune during the growing season. Trimming the plant can also stimulate new growth and promote a fuller appearance.
Propagation of Stapelia juvencula Jacq.
Stapelia juvencula Jacq. can be propagated through various methods. The most common methods of propagation include:
Seed Propagation
Stapelia juvencula Jacq. can be propagated from seeds. Sow the seeds in well-drained soil in a pot or seed tray during spring or summer. It is essential to keep the soil moist but not waterlogged. The seeds will germinate within two to four weeks and should be placed in a warm, bright location that receives indirect sunlight. Once the seedlings have reached a desirable size, they can be transplanted into bigger pots with well-draining soil.
Cuttings Propagation
Stapelia juvencula Jacq. can also be propagated from cuttings. Take a stem cutting that is at least 10 centimeters long and has a few leaves attached. Allow the cutting to dry out and callus over for a few days. After the cutting has callused over, place it in a pot with well-draining soil until roots emerge and new growth appears. It is best to take cuttings during the growing season and to keep them in a warm, bright location that receives indirect sunlight.
Division Propagation
Stapelia juvencula Jacq. can also be propagated through division. This method is best for mature plants that have grown too large for their current pot. Gently removes the plant from the pot and separate the root clumps before replanting them in well-draining soil in separate pots. Water the new pots and keep them in a warm, bright location that receives indirect sunlight.
Whichever method of propagation you choose, it is important to keep the newly propagated plants in a warm, bright location that receives indirect sunlight. Water the plants regularly but be careful not to over-water them. With proper care, the newly propagated plants will grow healthy and mature over time.
Disease and pest management for Stapelia juvencula Jacq.
Stapelia juvencula Jacq. is a succulent plant that belongs to the Apocynaceae family. Like any other plant, it can be subjected to diseases and pest attacks. To manage these problems, you should understand the common diseases and pests that might affect it and the ways to control them.

The disease mostly appears during the rainy season or when there is high humidity. The disease causes wilting, discoloration, and decay of the leaves, stems, and flowers. To manage the disease avoid wetting the leaves and stems, remove and destroy the infected plant parts, use fungicides to control the spread, and also improve the air circulation around the plant.
Another common disease that affects Stapelia juvencula Jacq. is root rot. The disease is caused by fungus and bacteria and can be facilitated by overwatering, poor drainage, and high humidity. To manage the disease, avoid overwatering, use well-draining soil, remove the infected plant parts, and apply fungicides.
Common pests
One of the common pests that affect Stapelia juvencula Jacq. is the mealybug. The pest is small, white, and covered with a waxy substance. The pest feeds on the sap of the plant and can cause wilting and stunted growth. To manage the pest, prune off the affected parts, apply insecticidal soap, and maintain cleanliness around the plant.
Another common pest that affects Stapelia juvencula Jacq. is the spider mite. The pest is very tiny, and you might not notice it until the damage is severe.
