Light Requirements

Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé is a tropical rainforest plant, which indicates that it thrives under shady conditions. It prefers bright, indirect light or dappled sunlight. Direct sunlight can cause the leaves to burn, and too much shade can reduce the plant's growth rate.

Temperature Requirements

The ideal temperature range for Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé is between 22°C to 28°C. The plant cannot grow in temperatures below 10°C or above 35°C. It is important to avoid placing the plant near air conditioners or vents that can cause temperature fluctuation.

Soil Requirements

The proper soil mix for Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé consists of a light, well-draining soil with a pH between 4.5-6.5. The soil should be rich in organic nutrients and able to retain moisture while also allowing air circulation. A mixture of peat moss, perlite, and bark fines would be a good choice for this plant.

Cultivation Methods

Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé, a species of evergreen shrub that belongs to the coffee family, is native to Central and West Africa. To cultivate this plant, you should use well-draining and rich soil that has a pH in the range of 6.0-6.5. Planting should take place during the rainy season to ensure adequate moisture for establishment.

Plant the shrub on a site that can provide the plant with partial or full sunlight exposure. The plant does not thrive under dense shade conditions. After planting, mulch the base of the shrub to reduce weed growth and regulate temperature.

Watering Needs

Regular watering is necessary for Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé to thrive. During the dry seasons, it is essential to water the plant adequately to keep the soil moist. Watering must be done when the soil's top layer is dry to the touch, but avoid over-watering the plant. Over-watering may cause root rot, which is detrimental to the plant.

Fertilization

Fertilizers are critical for Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé's successful growth and development. Apply a balanced fertilizer during the growing season, which may have a higher percentage of nitrogen. In contrast, a more balanced ratio of phosphorus and potassium is better suited for maintaining blooms and promoting strong roots. It is essential to follow the fertilizer's recommended application rates and schedules to avoid over-fertilizing, which may cause leaf burn or root damage.

Pruning

Pruning Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé is essential to stimulate new growth and develop an attractive shape. Dead or damaged leaves, stems, or branches must be removed periodically to encourage the plant's growth. Trim the shrub regularly to maintain a compact and bushy form, and promote better air circulation within the plant. Ideally, pruning should be done in the early spring before blooming occurs. Make clean cuts on the plant to heal properly and avoid infection by pathogens.

Propagation of Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé

Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé, commonly known as Walker's Coffee, can be propagated through various methods.

Seed propagation

Seeds can be collected from the plant when they turn black and are fully ripe. The seeds should be cleaned and soaked in water for a few hours. After soaking, sow the seeds in a potting mix composed of sand, loam and organic matter. The seeds should be watered regularly and placed in a well-lit area with a temperature range of 22-28°C. With proper care, the seeds will germinate in 4-6 weeks.

Cutting propagation

Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé can also be propagated through stem cuttings. Take a 10-15cm stem cutting from the parent plant, making sure that it has a few leaves. Remove the leaves from the bottom of the stem cutting and dip the end in rooting hormone. Place the cutting in a moist potting mix composed of sand, peat moss and perlite. Cover the pot with plastic wrap to create a greenhouse effect and place it in a warm and bright spot. After a few weeks, the cutting will produce roots and can be replanted in a bigger container.

Air layering propagation

Air layering is another propagation method for Tricalysia soyauxii K.Schum. var. walkeriana N.Hallé. Choose a healthy branch with a diameter of 1-2cm and make a small cut of about 2-4cm. Spread some rooting hormone on the cut area and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with a rubber band. Check the moss regularly and keep it moist. In 2-3 months, roots will emerge from the moss, and the cutting can be separated from the parent plant and potted in a well-drained potting mix.
