Common Names
The plant is commonly known as Kanna, Kougoed, Channa, and Kaugoed in Afrikaans. The Khoikhoi and San people of South Africa also refer to it as "Canna," which means "something to chew."
Appearance
Sceletium namaquense L.Bolus var. namaquense is a small plant that grows up to 30 cm in height. It has small, fleshy leaves that are pale green in color and triangular in shape. The flowers of the plant are yellow and appear in late spring to early summer. The plant is well-adapted to dry conditions and has a well-developed root system.
Uses
The plant has a long history of use among the Khoikhoi and San people as a mood enhancer and for its calming effects. It has been traditionally used to treat various ailments such as stress, anxiety, depression, and menstrual pain. The plant is also used as a natural remedy for headaches and to improve cognitive function.
Modern research on Sceletium namaquense L.Bolus var. namaquense has shown that it contains mesembrine, an alkaloid that acts as a serotonin reuptake inhibitor. This mechanism is similar to that of selective serotonin reuptake inhibitors, which are commonly prescribed antidepressants. As such, the plant is of interest to researchers for its potential therapeutic benefits in the treatment of depression, anxiety, and stress-related disorders.
Light Requirements
The Sceletium namaquense L.Bolus var. namaquense plant typically grows in full sun. However, it can also grow in partial shade in places where the sun's rays are strong. The plant requires a minimum of 6 hours of direct sunlight each day to thrive. In regions with hot climates, it is best to provide some shade during the hottest parts of the day.
Temperature Requirements
The Sceletium namaquense L.Bolus var. namaquense plant is native to regions that experience extreme heat and humidity, such as semiarid and arid regions. Therefore, it can tolerate high temperatures up to 38°C (100.4°F). However, it cannot tolerate frequent frosts, so the plant cannot survive in regions with extremely cold temperatures.
Soil Requirements
The Sceletium namaquense L.Bolus var. namaquense plant grows well in well-draining soils. It grows in sandy, loamy, or rocky soils. However, the plant requires a soil pH of 6.5-7.5 for optimal growth. The soil must be enriched with organic matter and essential nutrients, including nitrogen, potassium, and phosphorus. Adding humus to the soil can help retain moisture and improve the soil structure.
Cultivation Methods
When cultivating Sceletium namaquense L.Bolus var. namaquense, it is essential to choose a well-draining, nutrient-rich soil. The plant prefers a slightly acidic to neutral pH soil. Sow the seeds in trays during the spring or autumn, partly covering the seed with sand. Sceletium namaquense is vulnerable to frost, so it should be grown in a greenhouse. As a succulent, the plant enjoys ample sunlight, and a winter temperature of at least 10°C is necessary for optimal growth.Watering Needs
Sceletium namaquense requires regular watering during its growing season. It is a drought-resistant plant, but it is vital not to let the soil become too dry before watering. Water the plant only when the top layer of the soil dries out. Excessive watering can lead to waterlogging, root rot, and other conditions that compromise the plant's health.Fertilization
Sceletium namaquense requires minimal fertilization. The added nutrients can help improve the overall plant growth and productivity. Fertilize the plant two to three times a year with a slow-release fertilizer to provide the necessary nutrients for the plant to thrive. Be sure not to over-fertilize, which could lead to burning the roots or dehydrating the plant.Pruning
Pruning is essential when growing Sceletium namaquense L.Bolus var. namaquense. Prune the plant during the growing season to prevent it from becoming overly leggy and sprawling. Pruning encourages bushier growth and improves the overall plant's health. Cut back any yellowing or wilting leaves, as well as any leggy or damaged stems, to maintain the plant's appearance.Conclusion
Growing Sceletium namaquense L.Bolus var. namaquense requires proper cultivation, watering, fertilization, and pruning. By following these guidelines, you can enjoy a healthy and vibrant plant in your garden or greenhouse. With a little patience and care, your Sceletium namaquense plant will thrive and provide you with many years of enjoyment.Propagation of Sceletium namaquense L.Bolus var. namaquense
Sceletium namaquense L.Bolus var. namaquense is a perennial succulent with a trailing habit that belongs to the family Aizoaceae. Propagation of this plant can be achieved through several methods:
Seed propagation
Propagation of Sceletium namaquense L.Bolus var. namaquense can be done through the use of seeds. Sow the seeds in well-draining soil in a warm location with adequate sunlight. The germination process takes between two to four weeks. Once the seedlings are established, they can be transplanted to their permanent location.
Cuttings propagation
Sceletium namaquense L.Bolus var. namaquense can also be propagated from stem cuttings. Take cuttings from a healthy plant and let them dry in a shaded area for several days. Once the cuttings are dry, dip the cut ends into a rooting hormone and plant them in well-draining soil. Keep the soil moist and avoid direct sunlight until the cuttings develop roots and start to establish.
Division propagation
Sceletium namaquense L.Bolus var. namaquense can also be propagated through division. Carefully remove a section of the plant from the main clump, making sure to keep the roots intact. Plant the section in a well-draining soil mixture and water it thoroughly. Keep the soil moist and in a shaded area for the first few weeks until roots start to develop.
Disease Management
The Sceletium namaquense L.Bolus var. namaquense plant can be affected by a number of diseases that can affect its growth and overall health. Some of the common diseases that can affect this plant include:
- Fungal Infections: Fungal infections are one of the most common diseases that affect this plant, especially if the plant is grown in moist and humid conditions. Fungal infections such as powdery mildew, root rot, and downy mildew can affect the health of the plant, leading to stunted growth and poor yields.
- Bacterial Infections: Bacterial infections can also affect the plant, leading to the development of spots, wilting, and sometimes even death of the plant.
- Viral Infections: Viral infections can cause yellowing of the leaves, curling, distortion, and often necrosis of the plant tissue.
To manage these diseases, some of the measures that can be taken include:
- Practicing good farm hygiene by removing diseased plants and debris and keeping the area clean and well-ventilated.
- Using disease-free seeds or seedlings when planting and ensuring that the plants are spaced adequately to allow for proper air circulation.
- Regularly inspecting the plants for signs of disease and treating them promptly using appropriate fungicides and bactericides.
- Using disease-resistant cultivars when possible.
Pest Management
The Sceletium namaquense L.Bolus var. namaquense plant can also be attacked by pests, which can significantly reduce its yield and affect its overall growth. Some of the common pests that can attack this plant include:
- Spider Mites: Spider mites can cause damage to plant leaves by piercing them and sucking out the plant sap, leading to yellowing and discoloration.
- Thrips: Thrips are small insects that can cause distorted or stunted growth, discolored spots on the leaves and flowers, and premature leaf drop.
- Caterpillars: Caterpillars can feed on the leaves and the stems of the plant, leading to large holes and in severe cases, defoliation.
- Snails and Slugs: Snails and slugs can also feed on the leaves and the stems of the plant, leading to holes and damage.
To manage these pests, some of the measures that can be taken include:
- Crop rotation, to prevent the buildup of pests and diseases in the soil.
- Using insecticidal sprays, particularly when the pests populations are high.
- Using biological control methods, such as predatory mites, to control spider mites.
- Reducing excess moisture in the soil to control slugs and snails.
