Organic fertilizers such as compost and manure can also be applied and should be mixed into the soil well enough to reach the roots.
Pruning of Memecylon normandii Jacq.-Fél.
Pruning is beneficial for the growth and flowering of Memecylon normandii Jacq.-Fél. It should be done in late winter or early spring before the new growth appears. Dead or damaged branches should be removed to promote new growth and prevent disease spread.
Since the plant blooms on new growth, pruning can help improve the quality and quantity of flowers. The plant's size can also be controlled by regular pruning, but it is essential to avoid over-pruning, which can lead to stress and reduced flowering.
Propagation of Memecylon normandii Jacq.-Fél.
Propagation of Memecylon normandii Jacq.-Fél. can be done through various methods, including seeds, cuttings, and air layering.
Propagation through seeds
The easiest and most common method of propagation for Memecylon normandii Jacq.-Fél. is through seeds. The seeds should be collected from mature fruits of the plant. After collection, the seeds should be cleaned properly by removing the outer fleshy layer. Then, the seeds should be sown in a well-draining soil mixture with proper spacing and watering. The seeds usually germinate within 15 to 30 days, and after germination, they should be transplanted into separate containers.
Propagation through cuttings
Propagation through cuttings is another method of propagating Memecylon normandii Jacq.-Fél. Cuttings should be taken from mature, woody portion of the plant, preferably during early spring or summer. The cuttings should be approximately 6 to 8 inches long and should have at least two nodes. After taking the cuttings, the leaves should be trimmed off from the lower part of the cutting. Then, the cuttings should be planted in a well-draining soil mix and kept in a moist environment. The cuttings should root within 4 to 6 weeks, and they can be transplanted into separate containers.
Propagation through air layering
Air layering is a slow method of propagating Memecylon normandii Jacq.-Fél., but it is an effective way of getting new plants with the same characteristics as the parent plant. In air layering, a portion of the plant's stem is selected, and a section of bark is removed from this portion. Then, rooting hormone is applied to the exposed area of the stem, and it is covered with moist sphagnum moss and a plastic bag to maintain moisture. In this method, the roots develop directly on the stem, and after the development of roots, the stem can be cut and planted in a separate container.
Disease and Pest Management for Memecylon normandii Jacq.-Fél.

However, with imbalanced environmental conditions and poor cultivation or maintenance practices, the plant may become prone to a few diseases and pests.
Common Diseases
One of the common diseases that affect Memecylon normandii Jacq.-Fél. is the leaf spot disease. It occurs due to the accumulation of humidity on the leaves, which makes them a favorable environment for fungal growth. To prevent this, it's important to avoid watering the plant's leaves, particularly during the late afternoon or evening. The use of adequate fungicides can be useful in managing leaf spot disease.
Another disease that can affect Memecylon normandii Jacq.-Fél. is the root rot disease. It occurs because of overwatering, poor drainage, or soil-borne pathogens. To prevent this disease, it's important to avoid waterlogging the soil and to plant the shrub in well-drained soil. In case of the disease, the infected parts should be removed, and the soil should be treated with a fungicide to prevent the disease from spreading further.
