General Appearance
Schrebera goetzeana Gilg is a large tree that can reach up to 30m in height. It has a straight trunk with a diameter of up to 80cm. The bark is rough, dark brown, and vertically fissured. The leaves are simple, alternate, elliptic, and have a length of 7-12cm. The flowers are borne in clusters and have 5 yellow petals, giving them a star-like appearance. The fruit is a brown, woody capsule with 5 cells, each containing a single seed. The seeds are covered in a fleshy, edible aril.
Light Requirements
Schrebera goetzeana Gilg requires bright light to promote healthy growth and development. However, direct sunlight exposure for prolonged periods may cause damage to the leaves. It is recommended to place it in a location with filtered sunlight or partial shade.
Temperature Requirements
The plant grows best in warm to hot temperatures ranging from 20 to 35 degrees Celsius. It cannot withstand frost or temperatures below 10 degrees Celsius. It is best to keep it in a place where the temperature is consistent and does not fluctuate drastically.
Soil Requirements
Schrebera goetzeana Gilg prefers well-draining soils that are rich in organic matter. It thrives in soil with a pH range of 6.5 to 7.5. The addition of perlite or sand to the soil increases drainage and prevents waterlogging, which can cause root rot. Regular fertilization with a balanced fertilizer enhances growth and helps maintain its vibrant color.
Cultivation Methods
Schrebera goetzeana Gilg is a tropical evergreen tree that is cultivated for its ornamental value. To grow this plant successfully, choose a location that receives partial shade and provides protection from strong winds. The plant prefers well-drained soil that is rich in organic matter. Plant the tree in a hole that is twice the size of its root ball, and backfill with the soil mixture to cover the roots. Water the plant thoroughly and spread a layer of mulch around the base to conserve moisture.
Watering Needs
The watering needs of Schrebera goetzeana Gilg depend on the weather conditions and the age of the tree. Young plants require more frequent watering to establish their roots. This plant prefers evenly moist soil and needs watering when the top inch of soil feels dry to the touch. Water the plant deeply to encourage the roots to grow down into the ground. Avoid overwatering, as this can lead to root rot and other fungal diseases.
Fertilization
Schrebera goetzeana Gilg benefits from regular fertilization to promote healthy growth and development. Use a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer in the spring and summer months when the tree is actively growing. Follow the instructions on the package carefully to avoid overfertilization, which can damage the roots and leaves of the plant. Consider using a slow-release fertilizer that releases nutrients over time, reducing the need for frequent fertilization.
Pruning
Schrebera goetzeana Gilg requires minimal pruning, but it is a good idea to remove any dead, damaged, or diseased branches as soon as possible. Use sharp pruning shears to make clean cuts and avoid tearing the bark. You can also prune the tree to shape it or control its size, but be careful not to remove too much foliage at once, as this can weaken the plant. Prune the tree in late winter or early spring before the new growth begins.
Propagation of Schrebera goetzeana Gilg
Schrebera goetzeana Gilg, also known as the African milkplum or mchikichi, is a tree native to eastern and southern Africa. It produces small, yellowish-white flowers and edible fruits that are commonly eaten by birds and mammals. The tree is valued for its timber, which is used for making furniture and carvings, and for its medicinal properties. Propagation of Schrebera goetzeana Gilg can be done through different methods, including seed propagation, cutting propagation, and grafting.
Seed Propagation
The easiest and most common way to propagate Schrebera goetzeana Gilg is through seeds. The seeds can be collected from ripe fruits that have fallen onto the ground. The fruits must be washed and the pulp removed before the seeds are extracted.
The seeds should be planted in a mixture of well-drained soil and compost. They must be covered lightly with soil and kept moist. The pot or container should be placed in a warm, shaded area. The seeds usually germinate within 2-3 weeks.
Cutting Propagation
Schrebera goetzeana Gilg can also be propagated through cuttings. This method is usually used when the tree is older and harder to germinate from seeds. The cuttings should be taken in the early spring from the new growth. They should be about 6-8 inches long and have at least three leaves.
The cuttings should be planted in well-drained soil mixed with sand or perlite. They must be covered with a plastic bag or a clear plastic bottle to create a humid environment. The cuttings should be kept in a warm, shaded area and misted regularly. The roots usually develop within 4-6 weeks.
Grafting
Grafting is another method of propagating Schrebera goetzeana Gilg, but it requires more skill and experience. It involves taking a scion from a healthy tree and grafting it onto a rootstock of a related species that is compatible with the scion.
The scion should be taken in the early spring from the new growth and should be about 6-8 inches long and have at least three buds. The rootstock should be chosen carefully to ensure compatibility. The scion and the rootstock are joined by making a diagonal cut on both and attaching them together with a grafting tape or wax. The graft should be kept in a warm, shaded area until it has healed.
Propagation of Schrebera goetzeana Gilg can be done through different methods, depending on the availability of seeds, the age of the tree, and the skill level of the propagator. With the right conditions and care, the tree can be propagated successfully using any of these methods.
Disease and Pest Management for Schrebera goetzeana Gilg
Schrebera goetzeana Gilg is a deciduous tree that belongs to the Oleaceae family. It is commonly known as the African teak and is found in tropical Africa. The tree is commonly cultivated for its durable wood, but it is also valuable for its medicinal properties. Just like any other plant, Schrebera goetzeana Gilg is susceptible to diseases and pests. An integrated approach including sanitation, cultural practices, and chemical controls can help manage the diseases and pests.
Common Diseases
Anthracnose: Anthracnose is a fungal disease that affects many plants. The fungus typically attacks leaves, causing them to develop small, circular spots that gradually enlarge and turn brown. Severely affected plant parts may die. Anthracnose can be managed by pruning infected plant parts and raking up fallen leaves. Additionally, copper-based fungicides can be used to control the disease.
Leaf spot: Leaf spot is another fungal disease that affects Schrebera goetzeana Gilg. It causes small, circular spots on leaves that can merge, leading to defoliation. The disease is effectively managed by maintaining good tree hygiene. Infected plant parts should be pruned and destroyed, and copper-based fungicides should be sprayed to control the disease.
Common Pests
Shoot and Fruit borer: The shoot and fruit borer is a common pest that affects the Schrebera goetzeana Gilg. The larvae bore into the shoots and fruits of the tree, causing extensive damage. The pest can be controlled by spraying the tree with insecticides such as carbaryl, pyrethroids, and neem-based products.
Termites: Termites are a significant problem for Schrebera goetzeana Gilg. They feed on the wood of the tree, causing irreversible damage. The best way to control termites is to prevent them from gaining access to the tree by creating physical barriers such as metal mesh around the tree. Additionally, termiticides such as chlorpyrifos and fipronil can be applied to the soil around the tree to control termite infestation.
