Light Requirements
Fagara melanorhachis Hoyle thrives well under full sunlight, partial shade, and shade. Young plants might require more shading to avoid sun scorching their leaves, but once they're well established, they can withstand direct sunlight.
Temperature Requirements
The plant is native to Papua New Guinea, where temperatures range from 22°C to 32°C (72°F to 89°F). It, therefore, prefers temperatures that fall within this range. Temperatures below 10°C (50°F) are not suitable for Fagara melanorhachis Hoyle, and it might not survive if exposed to such conditions for very long.
Soil Requirements
Fagara melanorhachis Hoyle grows best in well-draining soils rich in organic matter. The soil pH should range from slightly acidic to slightly alkaline, with a pH between 6.0 and 7.5 being optimal. The plant prefers soils that are moist but not waterlogged, and it's sensitive to soils that are too dry or too wet. Mulching can help maintain soil moisture levels and regulate soil temperatures.
Cultivation Methods
Fagara melanorhachis Hoyle, commonly known as the Mountain Pepper, can be easily grown in well-drained soil with full sun exposure. The plant is moderately tolerant to drought conditions and can also withstand occasional frost. It can be grown in pots, raised garden beds, or directly in the garden soil.
Watering Needs
The Mountain Pepper requires regular watering, especially during the growing season. The soil should be kept moist but not waterlogged. It is recommended to avoid waterlogging of soil as it can lead to root rot. The frequency of watering should be adjusted according to the weather conditions and soil moisture level.
Fertilization
The plant needs regular feeding during the growing season. It should be fertilized with a balanced NPK (Nitrogen, Phosphorus, and Potassium) fertilizer every four to six weeks. The fertilization frequency can be adjusted according to the growth of the plant. Overfertilization should be avoided as it can lead to the burning of roots or even plant death.
Pruning
Fagara melanorhachis Hoyle is a relatively low-maintenance plant and does not require extensive pruning. Pruning should be done mainly for maintaining the plant's shape. It should be done during the dormant period, i.e., late winter or early spring. The dead or damaged branches should be pruned down to encourage new growth.
Propagation of Fagara melanorhachis Hoyle
Fagara melanorhachis Hoyle or Dong Quai Fruit is a small flowering tree that grows mostly in the subtropical regions of China, Vietnam, and other Southeast Asian countries. The plant can propagate through several methods, including:
Seed propagation
The plant produces a considerable amount of seed that germinates easily under favorable conditions. Before planting the seeds, prepare a well-draining potting mix of sand, vermiculite, and peat moss. Scatter the seeds over the soil surface and cover them with a thin layer of the soil mixture. Keep the soil consistently moist, with temperatures between 20°C to 25°C. The seeds will germinate within two to four weeks and grow into seedlings.
Cuttings propagation
The Fagara melanorhachis Hoyle tree propagates successfully from hardwood cuttings and semi-ripe cuttings. Take cuttings of about 15cm in length, and prune all leaves except the top two or three. Dip the cuttings into rooting hormone powder and plant them in a well-draining potting mix of sand and peat moss. Keep the soil mix moist, and maintain a high humidity level to encourage rooting. The cuttings will root within a few weeks, and it's time to transplant them to their permanent position.
Air-layering propagation
Air-layering is a propagation method that involves creating roots on a plant stem while it's still attached to the parent plant. To air-layer Fagara melanorhachis Hoyle, select a healthy branch and make a small incision on the bark. Wound the stem by removing a layer of bark. Cover the new wound with sphagnum moss and wrap it with transparent plastic to create a closed environment. Keep the moss moist and wait for roots to emerge from the wound. Sever the stem from the parent plant and plant it in a well-draining potting mix.
In conclusion, propagating Fagara melanorhachis Hoyle requires time and patience, but it's a rewarding experience. You can choose from seed propagation, cuttings propagation, or air-layering propagation, depending on the available resources and personal preference.
