Light Requirements
Notobuxus benguellensis (Gilg) E.Phillips thrives in full sun conditions. However, it can also tolerate partial shade. It is recommended to place the plant in a location where it can receive at least 5-6 hours of direct sunlight per day.
Temperature Requirements
The optimal growing temperature for Notobuxus benguellensis is between 20-25°C (68-77°F). The plant can tolerate slightly lower temperatures, but it cannot survive frost. It can struggle to survive in extreme heat conditions and is not suitable for areas with high humidity.
Soil Requirements
Notobuxus benguellensis thrives in well-draining soils. The pH level of the soil should be neutral to slightly acidic (6.0-7.0). It can grow in a variety of soil types, including loamy, sandy, and clay soils. However, the soil must be rich in nutrients to support the plant's growth. Consider adding organic matter, such as compost or leaf mold, to enrich the soil.
Cultivation Methods
Notobuxus benguellensis, also known as the Benguela boxwood, is a hardy evergreen shrub that thrives in well-drained soils with full sun exposure. This plant can be propagated through seeds or cuttings. For best results, choose a location in your garden where the plant can grow uninterrupted as it doesn't respond well to transplanting. Ensure that the soil is mixed with organic compost or peat moss before planting to aid drainage and moisture retention.
Watering Needs
Watering Notobuxus benguellensis should be done carefully to avoid waterlogging the shrub's root system. The soil should be checked for dryness before watering or when the leaves start to wilt. During the growing season, the plant should be watered deeply once a week. In winter, watering should be reduced to once every two weeks. Avoid watering when the soil is frozen, and water in the morning to prevent water loss through evaporation.
Fertilization
Notobuxus benguellensis benefits from regular fertilization during the growing season, from spring to summer. Use a slow-release fertilizer, high in nitrogen and potassium, to provide essential nutrients and stimulate growth. Fertilizers should be applied around the plant's base, and watering should follow immediately to promote absorption.
Pruning
Pruning is essential for maintaining the Benguela boxwood's shape and size and promoting bushy growth. This shrub can be pruned in early spring before the growing season. When pruning, use sharp and clean pruning shears to avoid damage to the plant. Prune selectively, removing dead or damaged branches and up to one-third of the plant's current growth. Avoid pruning in fall or winter, as this can weaken the plant and affect its growth in the following season.
Propagation Methods for Notobuxus Benguellensis (Gilg) E. Phillips
Notobuxus benguellensis, also known as the Benguela boxwood is a shrub or small tree belonging to the Buxaceae family, which is native to Angola and Namibia. It has small, glossy, and leathery leaves that are dark green in color. The species can propagate through various methods, including seed propagation, cuttings, and layering.
Seed Propagation
Notobuxus benguellensis can be propagated through seeds, which can be collected from mature fruits that are produced after pollination. The seeds should be cleaned and soaked in water for 24 hours to remove the fleshy layer around them, which can inhibit germination. After that, the seeds can be sown in seed trays containing sandy soil mixed with compost. The trays should be placed in a warm, well-lit area, and watered regularly to keep the soil moist. Germination will occur within 30 to 90 days, and the seedlings can be transplanted to a bigger pot after six months or when they have formed their first two true leaves.
Leafy Cuttings
Another propagation method suitable for Notobuxus benguellensis is cuttings. Leafy cuttings should be taken from new growth during the spring or summer when the plant is actively growing. The cuttings should be about 10 to 20 cm long and should have at least two leaves on them. The leaves on the lower half of the cutting should be removed to create a bare stem, which should be dipped in hormone rooting powder before being planted in a container filled with sand or perlite. The container should be placed in a warm and humid environment, and the cutting should be watered regularly to keep the soil moist. After six to eight weeks, the roots should have developed, and the cutting can be transplanted to a bigger pot.
Aerial Layering
Aerial layering is another method that can be used to propagate Notobuxus benguellensis. This method involves wounding a branch, wrapping it with sphagnum moss, and wrapping it with plastic to retain moisture. Roots will develop from the wounded region after a few months, and the new plant can be separated from the parent plant and potted up.
Disease and Pest Management for Notobuxus benguellensis
Notobuxus benguellensis is a small tree or shrub that is native to southern Africa. While it is generally considered a hardy plant, it is not immune to disease and pest problems. Here are some of the most common issues that may affect Notobuxus benguellensis and how to manage them:
Diseases
One of the most significant diseases that may affect Notobuxus benguellensis is root rot. Root rot is caused by various fungi, and it can quickly kill the plant. Symptoms of root rot include leaves that turn yellow, wilt, or fall off the plant. To prevent root rot, it is essential to avoid overwatering the plant. Ensure the soil has good drainage and avoid planting in areas where water is likely to accumulate.
Another disease that may affect this tree is leaf spot. Leaf spot is caused by a fungus that thrives in warm and humid conditions. Symptoms of leaf spot include dark spots or lesions on the leaves of the plant. To manage leaf spot, remove the affected leaves and destroy them to prevent the spread of the fungus.
Pests
Notobuxus benguellensis is also susceptible to insect infestations. One of the most common insects that may attack this plant is the aphid. Aphids feed on the sap of the plant, leading to stunted growth and distorted leaves. To manage aphids, you can use insecticidal soap or neem oil. Another insect that may attack this tree is the spider mite. Spider mites suck the sap from the plant leaves, causing stippling and discoloration. To manage spider mites, use an insecticidal soap or spray the plant with a strong jet of water to knock the mites off the plant.
Overall, Notobuxus benguellensis is a hardy plant that can tolerate a range of growing conditions. However, pests and diseases may still affect the plant, causing significant damage if not managed effectively. Regular inspection and appropriate management techniques are key to keeping this tree healthy and thriving.
