Cultivation methods for Melastomastrum afzelii var. paucistellatum
Melastomastrum afzelii var. paucistellatum is a shrub that grows best in tropical regions. It prefers well-drained soil and a sunny location to thrive. It is recommended to grow this plant in a container, allowing for easy movement and placement.
When planting in a container, it is best to use well-draining soil, compost, and perlite, mixed together in a 2:1:1 ratio. Plant the shrub at the same depth as it was in the nursery pot, and firm the soil around the plant.
Watering needs for Melastomastrum afzelii var. paucistellatum
Water Melastomastrum afzelii var. paucistellatum deeply but infrequently. It is best to keep the soil evenly moist, but not waterlogged, and avoid letting the soil dry out completely. During the dry season, it may be necessary to water more frequently, depending on the plant's environment and soil conditions.
Fertilization for Melastomastrum afzelii var. paucistellatum
Feed Melastomastrum afzelii var. paucistellatum every month during the growing season. Use a slow-release, balanced fertilizer with an NPK ratio of 10-10-10, or a liquid fertilizer diluted to half strength. Avoid fertilizing during the dormant season, as the plant is not actively growing and does not require additional nutrients.
Pruning for Melastomastrum afzelii var. paucistellatum
Prune Melastomastrum afzelii var. paucistellatum in early spring before new growth begins. Remove any dead, damaged, or diseased stems, and shorten any overly long or straggly branches. This will promote new growth and keep the plant healthy and bushy. Avoid pruning in the late fall or winter, as this may cause the plant to grow shoots that could be damaged by frost.
Propagation of Melastomastrum afzelii var. paucistellatum
Melastomastrum afzelii var. paucistellatum can be propagated through various methods such as seeds, cuttings and division.
Seed Propagation
The seeds of Melastomastrum afzelii var. paucistellatum need to be collected when they are ripe and dry. The seed coat has to be removed, and the seeds need to be stratified for at least a month before sowing in a mix of peat and sand. The seedlings should be kept in a shaded and moist area with good ventilation. It usually takes 4-6 weeks for the seeds to germinate.
Cutting Propagation
Cuttings can be taken from the semi-mature and mature stems of Melastomastrum afzelii var. paucistellatum. The cutting should be around 8-10 cm in length and include at least two nodes. The lower leaves should be removed, and the cutting should be dipped in rooting hormone powder before planting in a pot filled with a mixture of peat and sand. The pot should be kept in a shaded and humid area until the roots start to develop, which usually takes 3-4 weeks.
Division Propagation
In this method, the parent plant is dug out of the ground, and the roots are carefully separated into smaller sections ensuring each section has enough roots and stems. The sections should then be planted into pots filled with a well-draining peat and sand mixture. The pots should be kept in a shaded and humid area and watered frequently until the new growth starts to appear, which usually takes 3-4 weeks.
