Additionally, the berries of Lycium inerme are sometimes used to make tea or jam.
Overall, Lycium inerme L.f. is a hardy and versatile plant with a long history of use by indigenous peoples and a growing popularity as an ornamental plant.
Growth Conditions of Lycium inerme L.f.
Lycium inerme L.f. is a drought-resistant plant that grows in coastal regions and deserts. It is a woody perennial shrub that can reach up to 3 meters in height. It requires specific growth conditions for optimal growth and development.
Light Requirements
Lycium inerme L.f. requires full sunlight exposure to grow and develop properly. It should be planted in an area that receives about 6 to 8 hours of direct sunlight daily. Insufficient light can lead to weak and spindly growth, reduced flowering, and fruiting.
Soil Requirements
The plant grows well in well-drained soils that are neutral to slightly alkaline. It prefers soils that are sandy, loamy, or rocky. The ideal soil pH range for Lycium inerme L.f. is between 6.0 to 8.0. Poorly drained soils or heavy clay soils may cause root rot and stunted growth.
Temperature Requirements
Lycium inerme L.f. prefers warm temperatures between 20°C to 30°C (68°F to 86°F) for optimal growth and development. It can tolerate temperatures as low as -10°C (14°F) and as high as 40°C (104°F). The plant becomes dormant during the winter season when temperatures fall below 10°C (50°F).
Water Requirements
The plant is drought-tolerant but requires adequate water during its establishment period. Mature plants can withstand prolonged periods of drought, making them suitable for dry regions. Overwatering should be avoided, as it can lead to root rot and fungal diseases.
Cultivation of Lycium inerme L.f.
Lycium inerme L.f. is a hardy shrub that can tolerate a wide range of growing conditions. The plant prefers full sun, and well-draining soil. It is recommended to plant the shrub during the spring, after the last frost.
For optimal growth and yield, it is important to space the plants at least 3 to 4 feet apart. The shrub can grow up to 6 feet tall and 6 feet wide, so ensure that there is sufficient space for the plant to grow.
Watering Needs for Lycium inerme L.f.
During the first year of growth, it is important to water the plant regularly to establish the root system. After the first year, the plant can tolerate some drought. However, it is recommended to water the shrub deeply at least once a week during the growing season. Avoid overwatering, as the plant can develop root rot.
Fertilization of Lycium inerme L.f.
Fertilize the plant with a balanced fertilizer once every month during the growing season. This will provide the plant with the necessary nutrients for optimal growth and yield. Apply the fertilizer according to the manufacturer's instructions, and avoid overfertilizing, as this can lead to excessive vegetative growth.
Pruning of Lycium inerme L.f.
Prune the plant during the dormant season to promote bushier growth and increase yield. Remove any dead, diseased, or damaged branches. Also, prune any branches that are crossing or rubbing against each other. This will improve air circulation and reduce the risk of fungal diseases. Avoid pruning more than one-third of the plant at a time, as this can stress the plant.
Propagation of Lycium inerme L.f.
Lycium inerme L.f., commonly known as the thornless wolfberry, is a drought-resistant shrub that belongs to the family Solanaceae. It is native to Asian and Mediterranean regions and is known for its medicinal and nutritional properties. Propagation of this plant can be done through various methods, including seeds, cuttings, and layering.
Propagation by Seeds
Propagation of Lycium inerme through seeds is the most common method. The seeds should be collected from ripe fruits and cleaned before sowing. The seeds require scarification or pre-treatment before sowing, which involves breaking or weakening the seed coat to enhance germination. The pre-treatment can be done by nicking the seed coat or soaking the seeds in hot water for about 24 hours before sowing. The seedlings should be planted in well-draining soil and kept moist until germination, which usually occurs within two weeks.
Propagation by Cuttings
Propagation of Lycium inerme through cuttings is another popular method. The cuttings should be taken from mature, healthy plants during the vegetative phase. The cuttings should be at least 8–10 cm in length, and the leaves on the lower half of the cutting should be removed. The cuttings should be treated with rooting hormones before planting in well-draining soil and kept moist. The cuttings should be kept in a humid environment until they develop roots, which usually takes about four to six weeks.
Propagation by Layering
Propagation of Lycium inerme through layering is a simple method that involves bending a low-growing branch to the ground and covering it with soil. The branch should be wounded or nicked before bending to stimulate rooting. The branch should be kept in contact with the soil and kept moist until it develops roots, which usually takes about three to four weeks. Once the roots have developed, the new plant can be separated from the parent plant and replanted.
Disease Management
Lycium inerme L.f. is generally resistant to many diseases. However, certain fungal diseases might affect the plant, including powdery mildew and root rot. Powdery mildew appears as a white powder on the leaves and can be managed by adequate air circulation and avoiding high humidity conditions. As for root rot, it can be prevented by ensuring well-draining soil and avoiding over-watering the plant.
Pest Management
Lycium inerme L.f. can be vulnerable to some pests, including spider mites and aphids. Spider mites appear as tiny, spider-like insects that suck plant sap and cause yellowing of leaves. They can be managed by washing the plant with a strong stream of water or by using insecticidal soap or neem oil. As for aphids, they can be identified as small, pear-shaped insects that leave a sticky residue on the leaves. They can be controlled by introducing natural predators like ladybugs or by using insecticidal soap.
Regular monitoring of the plant can help in detecting pests and diseases early, which would prevent their spread and keep the plant healthy.
