To ensure optimal growth of this plant, specific conditions must be provided. The following are some growth conditions that should be considered:
Light
Tylostemon ngriki A.Chev. requires bright but indirect light. Direct sunlight can cause the leaves to turn yellow or brownish. Therefore, it is recommended to place the plant in a location where it can receive bright but filtered light for at least 6 hours a day.
Temperature
The plant prefers warm temperatures and is intolerant to cold. The ideal temperature range for Tylostemon ngriki A.Chev. is between 20°C to 30°C. The plant can tolerate slightly cooler temperatures at night, but it is best to avoid exposing it to temperatures below 15°C.
Soil Requirements
Tylostemon ngriki A.Chev. thrives in well-draining soils with a pH level between 5.5 – 7.0. The soil should be rich in organic matter and porous to facilitate good drainage. It is best to avoid soils that are heavy, compacted, or clayey as they tend to retain water, leading to root rot.
Watering
Watering is a critical factor to consider when growing Tylostemon ngriki A.Chev. Overwatering can lead to root rot while underwatering can cause the leaves to wilt and dry. It is best to water the plant when the top inch of the soil is dry. Ensure the pot has drainage holes to avoid waterlogging.
Fertilizer
Regular fertilization is recommended for Tylostemon ngriki A.Chev. to promote healthy growth and optimum flowering. Fertilizers with a balanced NPK ratio (nitrogen, phosphorus, and potassium) can be applied every two weeks during the growing season. Avoid over-fertilization as this can damage the roots and reduce the plant's vigour.
Cultivation Methods
The Tylostemon ngriki A.Chev. plant can be grown in both pots and the garden. When planting this plant, you must ensure it is done in an area that receives enough sunlight. It is recommended that you plant the Tylostemon ngriki A.Chev. plant in well-draining soil that has a pH level between 6.5 and 7.5. The planting hole should be twice as wide as the root ball. Ensure that you cover the roots with soil and water the plant immediately after planting.
Watering Needs
The Tylostemon ngriki A.Chev. plant should be given sufficient water to ensure it grows well. It is recommended that the plant be watered regularly but not excessively, to prevent waterlogging, which can damage the roots. During the growing season, the plant should be watered once a week, but during the dry winter months, you can reduce the watering frequency to once every two weeks.
Fertilization
Fertilizing the Tylostemon ngriki A.Chev. plant is not mandatory, but it can boost growth and improve the overall health of the plant. You may choose to use organic or inorganic fertilizer, but it is essential to follow the recommended dosage and frequency. It is recommended that you fertilize the plant every three months when the plant is actively growing. Avoid fertilizing the plant during the dormant season.
Pruning
The Tylostemon ngriki A.Chev. plant requires minimal pruning, but it is ideal to prune dead or damaged leaves and stems. It is essential to use sharp and sterilized pruning tools when pruning the plant. Prune the plant in early spring when the plant starts to grow to remove any dead or damaged parts. Additionally, pruning the plant can enhance its overall appearance.
Propagation of Tylostemon ngriki A.Chev.
Propagation of Tylostemon ngriki A.Chev. is best done through seeds or stem cuttings, as the plant does not propagate easily through division.
Propagation through seeds:
The best time to collect seeds is during autumn, when the seed pods of the plant start to dry up and open. The seeds should be sowed immediately after collection, and should be covered with a light layer of soil, and watered regularly. It is important to ensure that the soil is well-drained and kept moist, but not waterlogged. The ideal temperature for seed germination is between 20-25°C. The seeds should germinate within 14-21 days.
Propagation through stem cuttings:
Propagation through stem cuttings is also possible, and can be done during the spring or summer, when the plant is actively growing. Cuttings should be taken from healthy, mature stems, and should be approximately 10-15cm in length. The leaves on the bottom half of the stem should be removed, and the stem should be dipped in rooting hormone powder. The cutting should then be planted in a well-drained soil mixture, and kept moist by misting it regularly. It is important to keep the cutting in a warm, bright location, but out of direct sunlight. Rooting should occur within 4-6 weeks.
