Light Requirements
The plant Lycium prunus-spinosa Dunal needs plenty of sunlight to grow and thrive. It requires full sun exposure for at least 6-8 hours a day. If the plant is not exposed to enough light, it may result in stunted growth and low flower production. Inadequate light exposure can also make the plant susceptible to pests and diseases.
Temperature Requirements
The plant Lycium prunus-spinosa Dunal grows best in warm temperatures. It can tolerate a range of temperatures from 15°C to 35°C. The ideal temperature range for this plant is between 18°C to 25°C, and it does not tolerate frost well. Extremely low temperatures can cause the plant to die or suffer damage, while hot temperatures may cause wilting and dropped leaves.
Soil Requirements
Lycium prunus-spinosa Dunal prefers soils that are loose, well-drained, and have a pH range from 6.5 to 8.0. The plant does not thrive in wet soils, as this can cause root rot. The soil should also be fertile and rich in organic matter. Adding compost or aged manure to the soil can improve its fertility. The plant is moderately tolerant of saline soils but cannot tolerate waterlogged and poorly-drained soils.
Cultivation Methods
Lycium prunus-spinosa Dunal, commonly known as blackthorn wolfberry, prefers well-draining, loamy soil that is rich in organic matter. It grows best in regions with full sun exposure, but it can also tolerate partial shade. The plant grows well in USDA hardiness zones 5 to 9, where the temperature ranges between 15°F and 100°F.
You can grow the plant from seeds or cuttings. Sow the seeds in late winter/early spring, and they will germinate within two to three weeks. Transplant the seedlings when they reach 3-4 inches. For cuttings, take a 6-8 inch long cutting in the spring and dip in rooting hormone before planting in a potting mix.
Watering Needs
Blackthorn wolfberry prefers moderate watering, and it is tolerant of drought. However, you should water it immediately after planting, and keep the soil consistently moist for the first few weeks until it establishes roots. After that, water it once every week or two, depending on the weather conditions and the dryness of the soil. Avoid overwatering the plant as it can lead to root rot.
Fertilization
Blackthorn wolfberry requires a well-balanced fertilizer, which contains an equal amount of nitrogen, phosphorus, and potassium. Fertilize it in the early spring before the growing season begins and in mid-summer. Apply the fertilizer according to the manufacturer’s instructions. Avoid over-fertilizing as it can damage the plant.
Pruning
Pruning is not required for blackthorn wolfberry but is recommended to shape the plant and improve its health. Prune the plant in late winter or early spring by removing the dead, diseased, and damaged branches. Trim the branches that cross each other or rub against each other to prevent wounds and infections. You can also prune the branches that are too long or the ones that spoil the plant's shape.
Propagation of Lycium prunus-spinosa Dunal
Lycium prunus-spinosa Dunal, commonly known as the African boxthorn, is a hardy shrub that can grow up to 2 meters tall. Propagation of this plant can be done through seeds or cuttings.
Propagation by Seeds
Seeds of Lycium prunus-spinosa Dunal can be collected from mature and fully ripe berries. The collected seeds need to be cleaned and treated with a fungicide to prevent fungal infections. They should then be sown in seed trays filled with a well-draining soil mix. The trays should be kept in a warm and humid environment until the seeds germinate.
Propagation by Cuttings
Cuttings of Lycium prunus-spinosa Dunal can be taken during the summer months. Semi-hardwood cuttings about 15 cm long should be taken from the current season's growth. The bottom end of the cutting should be dipped in rooting hormone powder and then planted in a well-draining soil mix. The cuttings should be kept moist and in a shaded location until new growth appears.
Disease Management
Lycium prunus-spinosa Dunal is susceptible to several types of fungal and bacterial diseases. One of the most common is powdery mildew. Powdery mildew is a fungal disease that manifests as a white powdery coating on the leaves and stems of the plant. To manage powdery mildew, prune any affected branches or leaves, ensure proper air circulation around the plant, and apply a fungicide spray.
Another common disease that affects Lycium prunus-spinosa Dunal is leaf spot. Leaf spot is a fungal disease that causes small, circular lesions on the leaves of the plant. To manage leaf spot, remove infected leaves, apply a fungicide spray, and avoid overhead watering.
Crown rot is a bacterial disease that causes the plant's roots and base to rot. To manage crown rot, avoid overwatering, provide proper drainage around the plant, and remove any infected plants or plant parts to prevent the spread of the disease.
Pest Management
One of the most common pests that affect Lycium prunus-spinosa Dunal is the spider mite. Spider mites are tiny insects that feed on the plant's sap and cause yellowing leaves. To manage spider mites, remove heavily infested plant parts, spray with a forceful stream of water to dislodge the mites, and apply a miticide spray if necessary.
The aphid is another common pest that affects Lycium prunus-spinosa Dunal. Aphids are small insects that feed on the plant's sap and cause distorted, curled, or yellow leaves. To manage aphids, remove affected plant parts, apply a solution of water and dish soap to the affected areas, introduce beneficial insects like ladybugs or lacewings, or apply an insecticide spray.
The final pest that commonly affects Lycium prunus-spinosa Dunal is the whitefly. Whiteflies are tiny insects that feed on the plant's sap, cause yellowing leaves, and excrete honeydew that attracts ants. To manage whiteflies, remove infested plant parts, introduce beneficial insects like ladybugs or lacewings, apply a sticky trap to catch the flies, or apply an insecticide spray.
