Light
Rhus scytophylla Eckl. & Zeyh. var. dentata Moffett typically grows in full sun exposure. It is essential to provide this plant with plenty of direct sunlight for at least six hours per day to ensure proper growth and health.
Temperature
This plant can tolerate temperatures ranging from 0°C to 40°C. However, it thrives best in warm to hot climates with temperatures between 25°C to 35°C. In regions with cold winters, this plant may go dormant and lose its leaves during the winter season, but it will regrow in spring.
Soil
Rhus scytophylla Eckl. & Zeyh. var. dentata Moffett thrives in well-draining soils with a pH range of 5.5 to 7.5. It prefers soils with good organic matter content but can also grow in sandy or rocky soils. The plant can withstand occasional drought periods, but it requires moderate moisture to thrive and produce healthy foliage and flowers.
Cultivation Methods
Rhus scytophylla Eckl. & Zeyh. var. dentata Moffett, commonly known as Natal Karee, is easy to cultivate and requires minimum care. It thrives in full sun and well-drained soils. The plant can grow well in sandy, loamy, and clay soils. Natal Karee prefer soils that are slightly acidic, with a pH ranging from 6.0 to 6.5. The plant is drought-resistant and can tolerate moderate to high levels of salt.
Watering Needs
Natal Karee requires regular watering until it becomes established. Afterward, the plant is drought-resistant and requires minimal watering. Only water the plant when the soil is dry. Overwatering can cause root rot, which can damage the plant or lead to its death.
Fertilization
Fertilization is not essential for Natal Karee. However, applying an all-purpose fertilizer once a year can significantly enhance the plant's growth and flowering.
Pruning
Natal Karee does not require regular pruning. However, pruning can help maintain the plant's shape. Prune the plant during the spring season when new growth appears. Remove the damaged or dead branches. Additionally, you can prune the plant to control its size and shape.
Propagation of Rhus scytophylla Eckl. & Zeyh. var. dentata Moffett
Rhus scytophylla Eckl. & Zeyh. var. dentata Moffett, commonly known as the "Natal guarri" or "Natal sumac," is a shrub or small tree endemic to South Africa. It is a hardy plant that is drought-tolerant, and it is suitable for planting in semi-arid environments. Propagation of this plant can be achieved through several methods as follows:
Seed propagation
The most common and easiest method of propagating Rhus scytophylla is through seed propagation. The seeds are collected from the plant during the autumn period, which is usually from March to May in South Africa. The collected seeds are soaked in water for a few hours to remove the flesh surrounding them and then allowed to dry. The dried seeds are then either sown directly into prepared beds or in seedling trays filled with well-draining soil. The seeds should be covered with a thin layer of soil and kept moist until germination, which occurs within 2-4 weeks.
Cuttings propagation
Rhus scytophylla can also be propagated by using cuttings. Semi-hardwood cuttings are taken from new growth that is still green and somewhat flexible. The cuttings should be about 10cm in length, and the leaves on the lower part should be removed leaving only a few leaves on the top. The cut end of the stem should be coated with rooting hormone powder and inserted into a well-draining soil mix filled in a container. The container is then covered with a plastic bag to increase the humidity levels. The cuttings should be kept in a warm, shaded area and misted regularly until they develop roots, which take about 6-8 weeks. After rooting, they can be transplanted into larger containers or directly into the ground.
Suckers propagation
Rhus scytophylla can also be propagated through suckers. Suckers are new shoots that arise from the base of the parent plant. They can be dug out carefully with a spade and transplanted into pots or directly into the ground. Suckers are usually best taken during the dormant season, which is late autumn to early winter. The transplanted suckers should be watered regularly until they establish good root systems.
Disease and Pest Management for Rhus scytophylla Eckl. & Zeyh. var. dentata Moffett
Rhus scytophylla Eckl. & Zeyh. var. dentata Moffett, commonly known as "Nana-berry," is a popular garden plant with attractive foliage and berries. However, it is susceptible to certain diseases and pests that can harm the plant's health and appearance. Here are some of the common diseases and pests that can affect Rhus scytophylla var. dentata and ways to manage them effectively.
Diseases
Bacterial leaf spot: This disease causes small, water-soaked spots on the leaves, which later turn brown and fall off. To prevent bacterial leaf spot, avoid overhead watering and remove infected leaves promptly. Application of copper fungicides may be necessary.
Fungal leaf spot: Fungal leaf spots appear as circular, brownish-black spots with yellow halos. To manage this disease, prune affected leaves and avoid overhead watering. Applying fungicides like copper or sulfur sprays may help.
Powdery mildew: Powdery mildew is a fungal disease that causes a white, powdery coating on the leaves. To prevent powdery mildew, ensure good air circulation around the plant and avoid getting water on the leaves. Fungicides such as neem oil or sulfur sprays can also be effective in managing the disease.
Pests
Caterpillars: Caterpillars are common pests that can chew on leaves and cause extensive damage. To manage caterpillar infestations, pick them off by hand or apply insecticides like bacillus thuringiensis (Bt).
Mites: Rhus scytophylla var. dentata is susceptible to spider mite infestations, which cause yellow and brown spots on the leaves. To manage mite infestations, rinse the plant with water or apply insecticidal soap or neem oil.
Aphids: Aphids are small insects that suck sap from the leaves and cause them to wilt and yellow. To manage aphids, spray the plant with a strong stream of water or apply insecticidal soap.
Scale: Scale insects appear as small, brown bumps on the leaves and stems. To manage scale infestations, scrape them off with a brush or spray the plant with a horticultural oil.
By following these disease and pest management tips, you can help keep your Rhus scytophylla var. dentata healthy and attractive throughout the growing season.
