Notobuxus acuminata (Gilg) Hutch.
Notobuxus acuminata is a species of flowering plant in the family Buxaceae. It is commonly known as East African Boxwood and is native to East Africa, found in countries such as Tanzania, Kenya, Malawi, and Zimbabwe. The plant prefers high altitude forests, from 1,300 to 3,000 meters above sea level.
Appearance
The East African Boxwood is an evergreen shrub or small tree that can grow up to 6 meters tall. The plant has a rounded crown and dense foliage with small, dark green leaves. The leaves are oblong with pointed tips, measuring 1.5-3.5 cm long. The bark is gray and smooth, while the twigs are thin and brown.
Notobuxus acuminata produces small, yellowish-green, and unisexual flowers, which are grouped into clusters at the base of the leaves. The flowers bloom in the summer, from October to December, and are followed by small, fleshy, and red fruit that measures 1.2 cm in diameter.
Uses
The East African Boxwood has several uses. The plant is a source of a hard, yellowish-brown wood that is used for carving, making handles for tools, and producing charcoal. The wood is also used for furniture making and constructing musical instruments such as xylophones, marimbas, and drums.
Notobuxus acuminata has medicinal uses in some countries. The bark is used to treat fever, stomachache, and diarrhea, while the roots are used to treat malaria.
The plant is sometimes used as an ornamental plant in gardens and parks due to its dense foliage and rounded crown.
Growth Conditions of Notobuxus Acuminata (Gilg) Hutch.
Notobuxus acuminata is a small tree or shrub that belongs to the family Buxaceae. It is native to southern Africa and can be found in various habitats such as rocky outcrops, forests, and grasslands. Understanding the typical growth conditions is important for successful cultivation.
Light Requirements
In terms of light requirements, Notobuxus acuminata prefers partial shade to full sun. It can tolerate some level of shade, especially during the hottest part of the day. However, too much shade can result in weak growth and reduced flowering. Therefore, it is best to plant it in a spot where it can receive at least 4-6 hours of direct sunlight per day.
Temperature Requirements
Notobuxus acuminata grows best in a warm climate with a temperature range of 12°C to 29°C (54°F to 84°F). It can tolerate frost but is not well adapted to extremely cold temperatures. In areas with cold winters, it is advisable to protect the plant by covering it with frost cloth or relocating it to a warm spot indoors.
Soil Requirements
Notobuxus acuminata prefers well-draining soil that is rich in organic matter. It can tolerate a wide range of soil types, including sandy, loamy, and clay soils. However, it does not do well in waterlogged soil or soils with high salinity levels. The soil pH should be slightly acidic to neutral, ranging from 5.5 to 7.5. Adding compost or other organic matter to the soil before planting can help improve soil structure and fertility.
Cultivation Methods for Notobuxus acuminata
Notobuxus acuminata is a hardy evergreen plant that is relatively easy to grow. It can grow in both full sun and partial shade and is tolerant of a wide range of soil types. However, it prefers soils that are well-draining and slightly acidic to neutral in pH. To ensure proper growth of the plant, it is important to follow the appropriate cultivation methods.
First of all, it is recommended to plant Notobuxus acuminata in early spring or early fall before the onset of extreme temperatures. The planting hole should be slightly larger than the root ball, and the plant should be planted at the same depth as it was in its previous container. After planting, the soil should be watered thoroughly to help settle it around the roots.
Watering Needs for Notobuxus acuminata
Notobuxus acuminata requires regular watering to ensure proper growth and development. However, it is important not to overwater the plant, as this can lead to root rot and other issues. The frequency of watering will depend on factors such as temperature, humidity, and soil moisture levels.
A good rule of thumb is to water the plant deeply once or twice a week, depending on weather conditions. It is also important to allow the top inch of soil to dry out between watering sessions. This will help prevent waterlogging and promote healthy root growth.
Fertilization of Notobuxus acuminata
Notobuxus acuminata benefits from regular fertilization to promote healthy growth and foliage. A balanced, slow-release fertilizer is a suitable option for this plant. It should be applied once in early spring and again in late summer to provide the necessary nutrients throughout the growing season.
When applying the fertilizer, it is important to follow the instructions on the label carefully. Care should be taken to avoid getting the fertilizer on the foliage of the plant, as this can cause it to burn and turn brown. It is also recommended to water the plant well after fertilization to help distribute the nutrients evenly.
Pruning of Notobuxus acuminata
Notobuxus acuminata responds well to regular pruning, which helps promote bushier growth and maintain the desired shape and size of the plant. The best time to prune this plant is in early spring before new growth begins.
To prune the plant, simply use a sharp pair of pruning shears to trim back any dead or damaged branches and any branches that are growing out of shape. You can also cut back up to a third of the top growth to encourage branching and denser foliage. Avoid pruning during the summer months, as this can stress the plant and cause it to lose moisture.
Propagation of Notobuxus acuminata
Notobuxus acuminata (Gilg) Hutch. is a dioecious shrub that grows up to 3 meters in height. It is commonly found in the African continent, particularly in Cameroon, Ivory Coast, and Equatorial Guinea.
Seed Propagation
The primary method of propagating Notobuxus acuminata is through seeds. The ideal time for seed collection is during the fruiting season, which typically occurs between April and August. The fruit must be collected before it becomes overripe, as the seeds have a low rate of germination when overripe.
After collecting the seeds, they must be cleaned and dried. Stratification may be required to enhance germination rates. This is achieved by storing the seeds in a moist, cool environment for several weeks to up to three months.
After stratification, seeds can be planted in well-draining soil mixed with compost. The seeds should be planted at a depth of about 1-2 centimeters. Maintain adequate moisture levels, and seedlings should emerge within 2-4 weeks.
Cutting Propagation
Notobuxus acuminata can also be propagated through stem cuttings. The ideal time for taking cuttings is during the rainy season, which occurs in April to September for most parts of the African continent.
Cuttings should be taken from healthy, disease-free plants and should be at least 15-20 centimeters in length. The cuttings should be dipped in rooting hormone before being planted in a mixture of sand and compost.
The cuttings should be placed in a shaded area with high humidity. Water should be applied regularly, and after 3-4 weeks, roots should start to form. After the roots are well-established, the new plants can be transplanted into larger containers or directly into the field.
Layering Propagation
Another propagation method for Notobuxus acuminata is layering. This involves bending a lower branch of the plant to the ground and covering it with soil, allowing it to grow roots and separate from the parent plant.
For this method, young branches are chosen and bent to the ground. A small slit can be made in the center of a shallow hole in the soil, where the bent branches are placed. The branches should be covered with soil, leaving the tip exposed.
The tip of the branch should be pruned to allow for the growth of a new plant. The layered plant should remain in place for several months to a year before separating it from the parent plant. Afterward, it can be transplanted into a larger container or directly into the field.
Overall, Notobuxus acuminata can be propagated through a variety of methods. Seed propagation remains the most common method, but cutting and layering propagation can also be successful when done correctly.
Disease and Pest Management for Notobuxus acuminata (Gilg) Hutch.
Notobuxus acuminata (Gilg) Hutch., commonly known as African Boxwood, is a shrub that is native to Africa. It is a slow-growing, evergreen plant that can be susceptible to diseases and pests. Proper disease and pest management is crucial to maintaining the health and beauty of the plant.
