Propagation of Spondianthus preussii Engl. var. glaber (Engl.) Engl.
Spondianthus preussii Engl. var. glaber (Engl.) Engl., commonly known as Ngwungwulu in South Africa, is a tropical evergreen tree with a height of up to 30m. It is native to Cameroon, Central African Republic, Congo, Gabon, and Nigeria. The tree is valued for its hard, durable, and termite-resistant wood, which is used for making furniture, poles, and tool handles. It is also used in traditional medicine to treat fever, cough, and stomach ache.
The propagation of Spondianthus preussii Engl. var. glaber (Engl.) Engl. can be done by the following methods:
Seed propagation
Seeds of Spondianthus preussii Engl. var. glaber (Engl.) Engl. can be collected from mature fruits that fall off the tree. The seeds should be cleaned and sown immediately in a nursery bed that is prepared by loosening the soil and adding organic matter. The seeds should be sown at a depth of 2-3 cm and covered with soil. The nursery bed should be watered regularly to keep the soil moist. Germination may take 1-2 months, after which the seedlings can be transplanted to individual containers or the field.
Cuttings propagation
Cuttings of Spondianthus preussii Engl. var. glaber (Engl.) Engl. can be taken from mature branches of the tree during the rainy season. The cuttings should be 20-30 cm long and prepared by removing all leaves except for the top two. The cuttings should be treated with a rooting hormone and planted in a soil mixture of sand and peat moss. The cuttings should be kept in a shaded area and watered regularly to keep the soil moist. Rooting may take 4-6 weeks, after which the cuttings can be transplanted to individual containers or the field.
Air-layering propagation
Air-layering is a propagation method that involves creating a new plant from a mature branch while it is still attached to the parent plant. To air-layer Spondianthus preussii Engl. var. glaber (Engl.) Engl., a ring of bark should be removed from a healthy branch, and the exposed area should be treated with a rooting hormone. The area should then be wrapped with moist sphagnum moss and covered with plastic wrap. The moss should be kept moist, and roots may develop in 4-6 weeks. Once roots have formed, the layered branch can be cut off and planted in individual containers or the field.
Disease Management
Spondianthus preussii Engl. var. glaber (Engl.) Engl. is generally a hardy plant species, but it can still be affected by a few diseases. These diseases can potentially cause yield losses and reduce plant growth. Here are some of the common diseases that can affect Spondianthus preussii, and ways to manage them:
Leaf spot
Leaf spot is caused by a fungus and manifests as yellow and brown spots on the leaves. To manage this disease, it is recommended to immediately remove and destroy any infected plant parts, practice crop rotation, and use fungicides if necessary.
Anthracnose
Anthracnose is another fungal disease that causes leaf spots as well as stem and fruit rot. To control this disease, it is advisable to practice crop rotation, sanitation by removing and destroying infected plant parts, and using fungicides when necessary.
Pest Management
Besides diseases, Spondianthus preussii Engl. var. glaber (Engl.) Engl. can also have a few pests that can potentially harm the plant. Here are some of the common pests infesting the plant, and ways to manage them:
Spider mites
Spider mites are tiny arachnids that can be found on the underside of the leaves. They can cause leaf yellowing and eventually leaf drop if not addressed. To control spider mites, it is recommended to spray the plant with an insecticide or use predatory mites that feed on spider mites.
Mealybugs
Mealybugs are small, soft-bodied insects that suck plant sap, causing plant stunting, yellowing, and curling of the leaves. To manage mealybugs, it is advisable to prune and dispose of infested plant parts, use insecticidal soap, or apply horticultural oil sprays.
