Tricalysia lanceolata (Sond.) Burtt Davy plant requires partial shade to full sun exposure for optimum growth. It is a shade-loving plant that cannot tolerate direct sun exposure, especially during the hottest part of the day. Therefore, planting the plant in a location with some amount of shade or filtered sunlight is necessary.
Temperature Requirements
The ideal temperature range for the Tricalysia lanceolata (Sond.) Burtt Davy plant to survive and grow is between 18 to 25°C. It can tolerate minimum temperatures of up to 12°C and maximum temperatures of up to 30°C. Also, it cannot withstand frost or extreme temperatures, which could cause the plant's leaves to curl, wilt and eventually die.
Soil Requirements
The Tricalysia lanceolata (Sond.) Burtt Davy plant grows well in well-draining soils that are rich in organic matter. The soil PH should be between 5.5 and 6.5. It requires moist soil with good water retention capacity. The addition of humus, manure or compost to the soil during planting can offer the plant with the required nutrients in the soil.
Cultivation methods
Tricalysia lanceolata (Sond.) Burtt Davy, also known as the Forest tea plant, is native to the forests of South Africa. It grows best in warm temperatures and humid conditions with well-drained soil. It can be propagated by seeds or by stem cuttings.
When planting seeds, it is best to use a seed-starting mix with good drainage. The seeds should be kept moist but not overly wet, and it typically takes 1 to 2 months for the seeds to germinate. When planting stem cuttings, it is recommended to use a rooting hormone to encourage root growth.
The Forest tea plant can be grown both indoors and outdoors, but it should be protected from direct sunlight as it prefers partial shade. If growing indoors, ensure that it is placed near a window with indirect sunlight, and if grown outdoors, place it under other plants to protect it from the sun's harsh rays.
Watering needs
The Forest tea plant prefers consistently moist soil. It should be watered frequently during the growing season, especially during hot and dry weather. However, it is important to avoid overwatering as this can lead to root rot.
To ensure proper watering, check the soil's moisture level regularly. If the soil feels dry to the touch, it is time to water. During the winter months, the plant's water intake decreases, so reduce the watering frequency during this time.
Fertilization
The Forest tea plant benefits from regular fertilization, especially during the growing season. A general-purpose fertilizer can be used every 2-3 weeks to provide the necessary nutrients. Be sure to dilute the fertilizer as directed to avoid over-fertilization.
Organic fertilizers like compost or manure can also be used, and they provide a gradual and long-lasting source of nutrients. Apply organic fertilizers during the growing season and avoid applying too close to the stem to prevent stem rot.
Pruning
Pruning is not necessary for the Forest tea plant but can be done to maintain its shape, promote bushiness, and remove any dead or diseased foliage. Prune the plant in the early spring before new growth appears to avoid damage to new shoots.
To prune, use clean and sharp pruning shears to make cuts at a 45-degree angle just above a node or bud. This will promote new growth and prevent damage to the remaining plant. Remember to disinfect the pruning tools between plants to avoid spreading diseases.
Propagation of Tricalysia lanceolata (Sond.) Burtt Davy
Tricalysia lanceolata can be propagated using several methods, including seed propagation and vegetative propagation. The best time for propagation is during the wet season when the plant experiences active growth.
Seed propagation
The seeds of Tricalysia lanceolata are easily obtained since the plants produce a large number of fruits. The seeds are collected by hand from mature fruits that have fallen to the ground. Before sowing, the seeds are cleaned to remove any debris and then soaked in water for 24 hours to soften the seed coat. After soaking the seeds, they are sown in nursery beds made of a mixture of sand and compost. The seeds should be sown at a depth of 1-2 cm and watered regularly to maintain moisture levels. The seedlings will emerge after two to three weeks.
Vegetative propagation
Tricalysia lanceolata can also be propagated vegetatively using stem cuttings. The stem cuttings should be taken from mature plants during the rainy season when the plant is actively growing. The cuttings should be 10-15 cm long and taken from the softwood of the plant. The leaves should be removed from the bottom half of the cutting. The cuttings are then planted in a well-draining planting medium that is high in organic matter and kept in a shaded area with high humidity until they establish roots. Rooting takes about 2-4 weeks, and after that, the cuttings can be transplanted into pots or directly into the field.
Disease and Pest Management for Tricalysia Lanceolata
Tricalysia lanceolata is a plant that belongs to the Rubiaceae family and is commonly found in tropical and subtropical regions of Africa. It is a valuable plant due to its medicinal properties, which makes it important to protect it from pests and diseases that can reduce its quality and quantity.
Common Pests
The following are some common pests that might attack Tricalysia lanceolata:
- Leaf miners: These pests cause damage to the leaves by creating tunnels inside them. To manage them, remove and destroy affected leaves, and use insecticidal soap to control them.
- Mealybugs: Mealybugs can cause discoloration and dwarfing of the plant. Use insecticidal soap, neem oil, or horticultural oil to control them.
- Scale insects: They can cause yellowing of leaves and stunted growth. Use rubbing alcohol to remove them, or use insecticidal soap, neem oil, or horticultural oil to control them.
- Spider mites: Spider mites are common pests that can cause discoloration of leaves. The best way to control them is to wash the leaves with a strong stream of water or spray with insecticidal soap.
Common Diseases
The following are some common diseases that might affect Tricalysia lanceolata:
- Rust: Rust is a fungal disease that causes yellow and orange spots on leaves. To manage rust, spray affected leaves with fungicides, and remove and destroy infected parts of the plant.
- Leaf spots: Leaf spots are caused by fungi and bacteria, which cause black or brown spots on leaves. Remove and destroy affected leaves, and use fungicides to control the disease.
- Root rot: Root rot is caused by fungi that can cause roots to rot and die. Avoid overwatering the plant, and make sure that the soil has good drainage. Use fungicides to control the disease.
- Powdery mildew: Powdery mildew is a fungal disease that causes a white powder-like substance on the leaves. Remove and destroy affected leaves, and use fungicides to control the disease.
Overall, it is important to regularly check Tricalysia lanceolata for pests and diseases, and take prompt action to manage them to ensure that the plant grows and thrives well.
