Light Requirements
Teclea suaveolens prefers full sunlight exposure, but it can tolerate partial shade. It is recommended to place the plant in a location that receives at least six hours of direct sunlight daily.
Temperature Requirements
The plant can thrive in a wide range of temperatures, but it prefers warm and humid conditions. The optimal temperature range for Teclea suaveolens is between 15°C and 27°C.
Soil Requirements
Teclea suaveolens grows best in fertile and well-draining soil. It can tolerate different soil types, including clay, loam, and sandy soils. The pH of the soil should be slightly acidic to neutral, ranging from 6.0 to 7.0.
The plant requires moderate watering, and the soil should be kept moist but not waterlogged. Overwatering can lead to root rot and other issues, while under-watering can result in the plant's stunted growth.
Cultivation methods
Teclea suaveolens Engl. can be grown from seeds or cuttings. For seeds, plant them in well-draining soil in a pot or nursery bed. Cover the seeds with a thin layer of soil and keep them moist. Cuttings should be taken from healthy plants and planted in a mix of sand and potting soil. It is important to keep the soil moist but not waterlogged.
Watering needs
Teclea suaveolens Engl. prefers moderate watering. Avoid overwatering as it can lead to root rot. Water the plant when the top inch of soil is dry. In areas with high humidity, the plant may need less frequent watering.
Fertilization
Teclea suaveolens Engl. benefits from regular fertilization. Use a balanced fertilizer every three to four weeks during the growing season. Follow the manufacturer's instructions on the amount of fertilizer to use.
Pruning
Teclea suaveolens Engl. can be pruned to maintain its shape and size. Prune the plant during the dormant season by removing old and dead branches. You can also prune the plant to promote bushy growth. Pruning should be done with clean, sharp tools to avoid damaging the plant.
Propagation of Teclea suaveolens Engl.
Teclea suaveolens Engl. can be propagated through different methods that include:
Seed propagation
The easiest way to propagate Teclea suaveolens is through seed propagation. Fresh seeds have higher germination rates, and it is advisable to use them as soon as possible. To increase the chances of successful germination, it is best to soak the seeds in warm water overnight before planting them. The seeds should be planted in well-draining soil, and kept moist until they germinate. Germination usually takes around 2 to 3 weeks.
Cuttings propagation
Another way to propagate Teclea suaveolens is through cuttings. Hardwood cuttings are the best option during the dormant season. Cuttings should be around 15 cm in length, and it is recommended to take them from the previous year's growth. The cuttings should be treated with a rooting hormone before planting them in well-draining soil. It is important to keep the soil moist and the cuttings in a shaded area until they establish roots, which can take between 6 to 8 weeks.
Grafting propagation
Grafting is another method that can be used to propagate Teclea suaveolens, especially for commercial production. This method involves joining a scion from a desired cultivar with a rootstock from a closely related Teclea species. Grafting is typically done during the dormant season, and care should be taken to ensure that the graft union heals properly and does not dry out. The grafted plant should be kept in a shaded area with high humidity until it establishes itself.
Disease and Pest Management for Teclea suaveolens Engl.
Teclea suaveolens Engl., also known as African cherry orange, is a small tree or shrub found in many parts of Africa. Like all plants, it is susceptible to disease and pest infestations that can hinder its growth and yield.
