In conclusion, Terminalia rautanenii Schinz is a resilient and drought-resistant tree species that can thrive in a wide range of climatic and soil conditions. However, for optimal growth and development, the tree species requires full sunlight exposure, moderate temperatures, and well-drained soils with a pH range of 6.5 to 7.5.
Cultivation
Terminalia rautanenii Schinz, commonly known as the Puriri tree, is widely grown for ornamental purposes due to its attractive appearance. The tree thrives well in most soils, including sandy loam and clay soils that are well-draining. To grow this plant successfully, it needs a warm climate and a full sun position.
The best time to plant Puriri tree is during spring or early autumn. Dig a hole twice the size of the root ball and add some compost to the soil to improve its fertility. After planting, add some mulch to prevent moisture evaporation and keep the plant hydrated at all times.
Watering Needs
Puriri tree requires regular watering during the first couple of years after planting to establish a healthy root system. Once established, the plant can tolerate short periods of drought. Water deeply but infrequently, ensuring that the soil is adequately moist but not waterlogged.
Fertilization
To nourish a healthy and thriving Puriri plant, it needs regular feeding with a balanced fertilizer. Apply the fertilizer at the beginning of the growing season, preferably in spring to encourage robust growth and flower formation. Follow the package instructions regarding the amounts and frequency of application.
Pruning
Puriri tree requires minimal pruning to maintain its desired shape and size. The best time to prune the tree is during the dormant months, which usually fall between late winter and early spring. Avoid pruning during summer when the tree is actively growing, as this can promote weak growth and susceptibility to pests and diseases.
Propagation of Terminalia rautanenii Schinz
Terminalia rautanenii Schinz, also known as the green mountain plum or muhuhu, is a tree species native to East Africa and southern Africa. It is a valued wood species, and its bark and fruit also have traditional medicinal uses.
Seed propagation
Seed propagation is the most common and efficient method of propagating Terminalia rautanenii. The tree produces small, brown fruits that contain a single seed. The seed should be collected from ripe fruits, cleaned, and soaked in water for 24 hours before sowing.
Seeds can be sown directly into pots or seedbeds filled with well-draining soil, covered with a thin layer of soil, and watered. The seeds will germinate within two to four weeks. Once the seedlings have developed two to three true leaves, they can be transplanted to individual containers. The seedlings should be kept in a warm, sheltered location and watered regularly until they are established.
Cuttings propagation
Propagation of Terminalia rautanenii through cuttings is possible, but it is a more challenging and time-consuming method. Cuttings should be taken from young, semi-hard stems during the growing season and treated with a rooting hormone powder. The cuttings should then be planted in a rooting medium, such as a mixture of perlite and peat moss, and kept warm and moist until roots develop.
This method of propagation may take several months, and not all cuttings will successfully strike roots. However, it is a useful technique for propagating specific cultivars or varieties.
Grafting propagation
Terminalia rautanenii can also be propagated through grafting, but this method is not commonly used due to the species' tendency to produce suckers from the rootstock. Grafting is a technique that involves joining a scion, which contains the desired plant variety, with a rootstock from a compatible plant. The grafted plant will then grow with the desired characteristics of the scion.
In Terminalia rautanenii, grafting can be used to propagate specific cultivars or to introduce disease or pest resistance. However, care must be taken to manage sucker growth from the rootstock.
Overall, seed propagation is the most efficient and common method of propagating Terminalia rautanenii. Cuttings and grafting are more challenging techniques but may be useful for specific purposes.
