Light Requirements
Memecylon mouririfolium Brenan thrives best in direct sunlight or partial shade. It requires at least 6 hours of sunlight exposure per day. However, it is also essential to protect the plant from scorching sunlight as it can cause leaf burn and damage.
Temperature Requirements
This plant prefers a warm and humid climate and thrives well in temperatures ranging from 20 - 35°C. The minimum temperature required for growth is 15°C and anything below can cause damage to the plant. It is also important to note that this plant cannot tolerate frost or extreme cold temperatures.
Soil Requirements
Memecylon mouririfolium Brenan prefers well-drained soils with a pH range of 5.5 - 6.5. The soil should be rich in organic matter and have good water-holding capacity. Avoid waterlogged soils as they can lead to root rot and stunt plant growth. It is recommended to add a layer of mulch to the soil to help retain moisture.
Cultivation
Memecylon mouririfolium Brenan is best grown outdoors in its native tropical environments. It thrives in rich, well-drained soils with a pH between 5.5 and 7.5. The plant requires partial shade or filtered light when grown in containers to prevent leaf scorching. It is important to ensure that the plant is protected from strong winds and cold temperatures as it is highly sensitive to frost.
Watering
Frequent watering is necessary for the plant to maintain optimal growth and development. Overly dry soil can cause the plant's leaves to turn yellow and fall off. Keep the soil moist but not overly saturated as this can lead to root rot. During winter, reduce watering and let the soil dry out between waterings.
Fertilization
It is recommended to fertilize the plant regularly during the growing season using a balanced fertilizer. This will support healthy growth and flowering. Overfertilization can cause the plant's leaves to turn yellow, and the plant to become overgrown and leggy. Follow the instructions on the fertilizer package and avoid applying fertilizer to dry soil to prevent root burn.
Pruning
Pruning can be done to maintain the plant's shape and ensure that it does not become too leggy or overgrown. Prune the plant to remove damaged or dead branches and promote airflow and light penetration. Pinch back the tips of new growth to encourage bushier growth. Pruning should be done in early spring before new growth appears.
Propagation of Memecylon mouririfolium Brenan
Memecylon mouririfolium Brenan can be propagated through the following methods:
1. Seed propagation
Seeds are collected from ripe fruits and washed with clean water to remove any pulp or debris. The cleaned seeds are then dried in the sun for a few hours. The seeds can be sown directly in pots or in a seedbed.
If sowing in a seedbed, the soil must be well-draining and fertile. The seeds should be sown at a depth of 0.5-1 cm in rows or broadcasted evenly. The seedbed should be watered regularly to maintain moisture levels. Germination will occur in 2-4 weeks, and the seedlings can be transplanted to individual pots after 4-6 weeks.
If sowing directly in pots, fill the pots with a well-draining potting mix and place one seed in each pot. Cover the seeds with a thin layer of potting mix and water thoroughly. The pots should be kept in a warm, humid place until germination, which usually occurs in 2-3 weeks.
2. Vegetative propagation
Memecylon mouririfolium Brenan can also be propagated vegetatively through stem cuttings and air layering.
Stem cuttings: Select a healthy stem with no flowers or fruits. Cut a 15-20 cm long stem from the parent plant and remove all the leaves except for two at the top. Dip the cut end of the stem in rooting hormone powder and plant it in a well-draining potting mix. Water thoroughly and cover the pot with a plastic bag to maintain humidity. Place the pot in a warm, bright place and mist the cutting regularly. Roots will develop in 4-6 weeks, and the new plant can be transplanted to a larger pot or in the ground.
Air layering: Select a healthy stem with no flowers or fruits. Make a small 1-2 cm cut on the stem, and wrap it with a moist sphagnum moss or cocopeat. Cover the moss with plastic wrap and tie it securely with twine. The moss should be kept moist by spraying water regularly. Roots will develop in 4-6 weeks, and the rooted portion can be cut off and planted in a pot or in the ground.

This plant is known for its ornamental value, medicinal properties, and ecological importance. However, like any other plant, it is susceptible to various diseases and pests that can affect its growth, yield, and overall health.
Common Diseases
Leaf Spot - Leaf spot is a common fungal disease that affects the leaves of Memecylon mouririfolium. The disease is characterized by the appearance of small, circular, red, or brown spots on the leaves. The spots may coalesce and form larger lesions that can cause defoliation and weaken the plant. To manage the disease, it is recommended to remove infected leaves, improve air circulation around the plant, and apply fungicides.
Powdery Mildew - Powdery mildew is a fungal disease that affects the leaves, stems, and flowers of Memecylon mouririfolium. The disease is characterized by the appearance of a white, powdery substance on the plant's surface. The affected parts may become distorted, stunted, and wither. To manage the disease, it is recommended to remove infected plant parts, maintain proper air circulation and humidity levels, and apply fungicides.
Common Pests
Aphids - Aphids are small, soft-bodied insects that suck the sap from the leaves and stems of Memecylon mouririfolium. The infested parts may become distorted, yellow, and fall prematurely. To manage aphids, it is recommended to wash the plant with a strong stream of water, apply insecticidal soap, or introduce natural predators like ladybugs and lacewings.
Spider Mites - Spider mites are tiny arachnids that feed on the sap of Memecylon mouririfolium. The infested parts may have tiny stippling or yellowish speckles, and the leaves may become dry and brittle. To manage spider mites, it is recommended to wash the plant with a strong stream of water, apply insecticidal soap or neem oil, or introduce predatory mites or insects like Phytoseiulus persimilis or Stethorus punctum.
Scale Insects - Scale insects are small, oval-shaped insects that suck sap from the leaves and twigs of Memecylon mouririfolium. The infested parts may have a sticky, shiny substance, and the leaves may turn yellow and fall off. To manage scale insects, it is recommended to remove them manually with a cotton swab dipped in alcohol, prune heavily infested parts, or introduce natural enemies like ladybugs, lacewings, or parasitic wasps.
