Propagation through seeds is the most common method for Memecylon brenanii. Mature fruits are collected from healthy plants and soaked in water for a few hours. The pulp is then removed, and the seeds are washed with water. Seeds are sown in a potting mix of soil and sand, and it takes about 10 to 15 days for germination.
Another method of propagation is through cuttings. Semi-hardwood cuttings of about 6 inches in length are collected from healthy plants. The leaves from the lower half of the cutting are removed, and a rooting hormone is applied to the cut end. Cuttings are planted in pots filled with a mixture of soil and sand, and they take about 4 to 6 weeks to develop roots.
Air layering is another propagation method used for Memecylon brenanii. A slanting cut is made on a healthy stem, and a rooting hormone is applied to the cut area. The area is then wrapped with moss, covered with plastic, and secured with a string. Roots develop within a few weeks, and the stem can be cut off the main plant and planted in a potting mix.
