Light Requirements
Rhus synstylica R. & A.Fern. var. synstylica needs plenty of sunlight to grow well. It typically requires full sun exposure for at least 6 hours per day. Therefore, it's important to place the plant in a location that receives plenty of direct sunlight. Without enough sunlight, the plant may not thrive and may develop weak stems and leaves.
Temperature Requirements
This plant prefers warm temperatures ranging between 60°F (16°C) and 85°F (29°C). The plant cannot tolerate extreme cold or frost. Therefore, ensure that you protect it from cold and frost by keeping it indoors during winter. If you live in a cold climate, ensure that you keep the plant in a warm location away from cold drafts. If you notice any yellowing or withering of leaves, it could be a sign that the plant is experiencing temperature shock.
Soil Requirements
Rhus synstylica R. & A.Fern. var. synstylica grows best in well-drained soil that is organically rich. The soil should be slightly acidic with a pH of 6.0 to 7.0. The plant requires adequate moisture to grow well, but it should not be overwatered as it can lead to root rot. Ensure that the soil is well-drained and does not retain excess water. You can add organic compost to enrich the soil and promote proper drainage. Additionally, adding a layer of mulch around the plant can help retain moisture and prevent weeds from growing.
Cultivation
Rhus synstylica R. & A.Fern. var. synstylica, also known as the African sumac or taaibos, is native to southern Africa. It is a hardy plant that is tolerant of drought and heat. The best time to plant African sumac is in the spring, as this allows the plant to establish a strong root system before the hot summer weather sets in.
When planting African sumac, it is important to choose a location with well-draining soil and good sun exposure, as this will help the plant thrive. The plant should be spaced at least 6 to 8 feet apart to allow for proper growth.
Watering Needs
African sumac is drought tolerant and does not require regular watering. However, young plants should be watered once a week during the growing season to encourage proper root growth and establishment. Once the plant is established, it can survive on natural rainfall alone. Overwatering can lead to root rot and other plant health issues, so it is important to avoid excess watering.
Fertilization
African sumac is a hardy plant that does not require regular fertilization. However, if you want to encourage the plant to grow more quickly or achieve fuller growth, you can use a general-purpose fertilizer once a year in the spring. Avoid using fertilizer during the summer months, as this can damage the plant.
Pruning
African sumac requires minimal pruning to maintain its shape and promote healthy growth. Pruning should be done during the dormant season, which is typically in late fall or early winter. During this time, you can remove any dead or damaged branches, as well as any branches that are crowding the center of the plant and preventing proper air circulation. You can also shape the plant as desired to encourage fuller growth and a more attractive appearance.
Propagation of Rhus synstylica R. & A.Fern. var. synstylica
Propagation of Rhus synstylica R. & A.Fern. var. synstylica can be done through seeds or by vegetative means such as cuttings or layering.
Propagation through Seeds
Seeds of Rhus synstylica R. & A.Fern. var. synstylica can be collected from ripe fruits. The seeds need to be cleaned and soaked in water for 24 to 48 hours to soften the hard seed coat. After soaking, the seeds can be sown in well-draining soil in pots or nursery beds. The seedlings should be kept in a shaded area and watered regularly. Germination usually takes 3 to 4 weeks.
Propagation through Cuttings
Cuttings of Rhus synstylica R. & A.Fern. var. synstylica can be taken from mature stems during the growing season. The cuttings should be around 15 cm long and have at least 2 to 3 nodes. The bottom nodes should be removed, and the cuttings should be treated with rooting hormone. The cuttings can be planted in well-draining soil in pots or nursery beds. The cuttings should be kept in a shaded area and watered regularly. Rooting usually takes 4 to 6 weeks.
Propagation through Layering
Layering is a propagation method where a branch from the plant is bent to the ground and covered with soil. The branch should be wounded where it contacts the soil to encourage rooting. After a few months, roots will form, and the branch can be cut from the parent plant and potted or transplanted.
Disease Management
Rhus synstylica R. & A.Fern. var. synstylica is susceptible to various diseases that can cause damage to the plant. One of the most common diseases that affect this plant is powdery mildew. Powdery mildew is a fungal disease that appears as a white or grayish powder on the leaves and stems. To manage this disease, it is crucial to maintain good air circulation around the plant and avoid watering the foliage. In case of severe infection, fungicidal sprays may be necessary.
Another disease that can affect Rhus synstylica is anthracnose, a fungal disease that causes leaf spots and cankers on the stems. To manage anthracnose, remove the infected part of the plant and destroy it. Avoid overhead watering and apply a fungicidal spray to protect the plant from further infection.
Pest Management
Rhus synstylica is also susceptible to pests, which can cause significant damage to the plant. One of the most common pests that affect this plant is the scale insect. Scale insects are tiny, oval-shaped insects that suck sap from the leaves, stems, and branches, causing yellowing and distortion of the foliage. To manage scale infestation, it is essential to prune the infected parts of the plant and apply a horticultural oil spray to kill the insects and their eggs.
Another pest that can affect Rhus synstylica is the spider mite, which causes yellowing and stippling of the leaves. To prevent spider mite infestation, ensure that the plant is adequately watered and humid. If an infestation occurs, apply a miticidal spray and keep the plant well watered and humid until the infestation is under control.
