The tree's leaves are pinnately compound, with 5 to 15 leaflets that are oblong-obovate to oblong-elliptic in shape, and measure between 6 and 13 centimeters long. The leaves are dark green and glossy, with a slightly serrated edge. The plant produces small, white flowers, which are followed by berry-like fruits that are between 1.5 and 2 centimeters in diameter.
Uses

The bark of the tree also contains compounds that have anti-inflammatory and anti-cancer properties. Aside from its medicinal properties, the plant is also cultivated as an ornamental tree in gardens and parks due to its attractive foliage, flowers, and fruits.
Light Requirements
Melicope clusiifolia requires full to partial sunlight exposure for optimum growth. It cannot survive in areas with complete shade. It thrives well in open spaces with enough exposure to light and unobstructed airflow.
Temperature Requirements
The plant can withstand temperature fluctuations but grows best in a warm and humid environment. The ideal temperature range for its growth is between 20°C to 30°C. Temperatures below 12°C or above 40°C have adverse effects on the plant's growth and development.
Soil Requirements
Melicope clusiifolia grows well in well-drained soils rich in organic matter. The ideal soil pH range is moderately acidic to slightly alkaline (pH 5.0 to 7.5). The plant's roots are shallow and require a loamy soil structure that provides enough aeration and good water retention to prevent waterlogging. It can tolerate different soil types but prefers soils with high fertility.
Cultivation Methods
Melicope clusiifolia (Gray) T.G. Hartley & B.C. Stone, commonly known as Clusia-leaved Melicope, is a tropical plant that thrives in warm and humid conditions. It is relatively easy to grow and cultivate as long as certain conditions are met.
The plant prefers full sun to partial shade and well-draining soil that is rich in organic matter. It is advisable to plant it in a spot that receives at least six hours of sunlight daily. It is also important to ensure adequate spacing between plants to avoid overcrowding.
Watering Needs
Like most plants, Melicope clusiifolia requires regular watering to thrive. However, overwatering can be detrimental to the plant as it is susceptible to root rot. It is advisable to water the plant when the soil is dry to the touch, but not completely dry. The frequency of watering depends on factors such as temperature, humidity, soil type, and container size.
It is important to note that excessive watering can lead to soft growth, which in turn attracts pests and diseases. Therefore, it is advisable to water the plant carefully and avoid getting water on the leaves as this can lead to fungal infections.
Fertilization
Melicope clusiifolia requires regular fertilization to thrive. It is advisable to use a balanced fertilizer with a ratio of 10-10-10 or 20-20-20. The fertilizer should be applied every two to three months during the growing season, which is usually from spring to fall.
It is important to follow the manufacturer's instructions when applying the fertilizer to avoid overfeeding the plant, which can lead to soft growth, pest, and disease problems. Alternatively, organic fertilizers such as compost, manure, or bone meal can be used to enrich the soil.
Pruning
Pruning the Melicope clusiifolia is essential to maintain its shape and promote healthy growth. It is advisable to prune the plant during the dormant season, which is usually in the winter. The pruning can be done to remove dead or damaged branches, shape the plant, or to control its size.
It is important to use sharp and sterile pruning tools to prevent damaging the plant or introducing diseases. It is also advisable to remove any crossing branches to prevent rubbing and damaging the bark.
Propagation of Melicope clusiifolia
Melicope clusiifolia is a popular shrub that belongs to the Rutaceae family. Propagation of this plant can be done through various methods, including:
Seed Propagation
Seeds of Melicope clusiifolia can be collected from the plant during the fruiting season. The seed needs to be cleaned and stored in a dry and cool place until the start of the next growing season. Before sowing, seeds can be soaked in warm water for at least 24 hours to increase the germination rate. Sow the seeds in peat pots with potting mix and keep them moist and warm. Germination may take around 3-4 weeks. Seedlings can be transplanted to individual pots when they reach a height of 2-3 inches.
Cutting Propagation
Melicope clusiifolia can also be propagated using stem cuttings. Cut off healthy and mature stems from the plant with a sharp and clean knife. The cuttings should be around 6-8 inches long and should not have any flowers or buds. Clean the bottom end of the cutting and dip it into rooting hormone powder. Plant the cuttings in a well-draining potting mix and water thoroughly. Cover the pot with a plastic bag or glass dome to retain humidity. Keep the cutting in a bright light and warm place until roots develop, which may take around 1-2 months. Once roots have developed, the cutting can be shifted to a bigger pot or planted in the ground.
Air Layering
Air layering is another propagation method for Melicope clusiifolia. For this method, select a healthy stem and make a small cut into the bark at a point where you want the roots to develop. Apply rooting hormone powder to the wound and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and tie it securely with a string. Keep the spot moist and wait for roots to develop. Once the roots are well-established, cut the stem from the parent plant and plant it in a pot or in the ground.
Disease and Pest Management for Melicope clusiifolia
Melicope clusiifolia (Gray) T.G. Hartley & B.C. Stone, commonly known as the Clusia-leaved pelea, is a shrub or small tree that is native to tropical regions.

The Melicope clusiifolia is susceptible to fungal diseases such as powdery mildew, anthracnose, and root rot. These diseases can cause discolored leaves, wilting, and can eventually kill the plant if left untreated. To manage these diseases, one must ensure proper drainage, avoid overwatering, and removal of any diseased plant parts. Fungicides such as copper-based or sulfur-based can also help manage fungal diseases in Melicope clusiifolia.
Preventative Measures
Preventative measures are essential to maintaining healthy plants. Adequate watering, proper fertilization, and providing the right growing conditions can help prevent pest and disease infestation. Additionally, practicing good hygiene, such as regularly cleaning gardening equipment, can help prevent the spread of disease between plants. Finally, planting Melicope clusiifolia in a location that allows for good air circulation and sunlight can also help prevent pest and disease problems.
By following the above pest and disease management tips, gardeners can keep their Melicope clusiifolia healthy and thriving.
