Cultivation Methods
Memecylon oubanguianum Jacq.-Fél. is a hardy plant that requires well-draining soil and partial shade to full sun exposure. It can be grown successfully in a variety of soil types, including loam, sand, and clay, as long as the soil provides adequate drainage. When planting, make sure to dig a hole twice the width of the container and the same depth as the root ball. Amend the soil with compost and organic matter for optimal growth.
Watering Needs
Memecylon oubanguianum Jacq.-Fél. requires regular and consistent watering until it is established in the soil, which usually takes about a year. Afterward, the plant can tolerate short periods of drought. Watering should be done deeply and less frequently to promote deeper root growth and prevent root rot. During the growing season, water the plant once or twice a week, depending on the weather, to keep the soil moist and not waterlogged.
Fertilization
Memecylon oubanguianum Jacq.-Fél. benefits from occasional fertilization to promote growth and blooming. Use a balanced, slow-release fertilizer, or organic fertilizer, once every 2-3 months during the growing season. Avoid fertilizing the plant during the winter months when growth slows down.
Pruning
Memecylon oubanguianum Jacq.-Fél. requires minimal pruning. However, you can prune the plant to promote bushier growth and control its size if it outgrows its space. After blooming, deadhead the spent flowers and prune back the branches to encourage new growth. To maintain the plant's shape, pinch back the tips of the young branches.
Propagation of Memecylon oubanguianum Jacq.-Fél.
Memecylon oubanguianum Jacq.-Fél. can be propagated by both sexual and asexual methods.
Sexual propagation
Seeds of Memecylon oubanguianum Jacq.-Fél. can be collected from mature fruits and sown in a well-draining potting mix. The seeds should be sown at a depth of 1-2 cm and kept moist but not waterlogged. Germination can take anywhere from 15 to 60 days and requires warm temperatures between 20-30°C. Once the seedlings have grown a few leaves, they can be transplanted into separate pots or a well-draining garden bed.
Asexual propagation
Memecylon oubanguianum Jacq.-Fél. can also be propagated asexually through stem cuttings. Semi-hardwood cuttings of about 10-15 cm in length can be taken from healthy plants during the growing season, preferably in the early morning or late evening to avoid wilting. The cuttings should be treated with a rooting hormone to encourage root growth and planted in well-draining potting mix. The cuttings should be kept moist and warm with temperatures between 20-30°C and protected from direct sunlight until roots have formed. Once rooted, the cuttings can be transplanted into separate pots or a garden bed.
Multiplication of Memecylon oubanguianum Jacq.-Fél. through layering can also be done by burying a lower branch of the plant in the soil, pinning it in place, and keeping it moist until roots have formed. The new plant can then be separated from the parent plant and transplanted.
