Division Propagation: Renewing Mature Lemongrass for Healthy New Growth
Division propagation is one of the easiest and most reliable methods for growing new lemongrass plants. As mature lemongrass clumps become dense over time, separating the older clumps into smaller sections helps rejuvenate the plants, encourages vigorous growth, and provides healthy seedlings for expanding the garden. This simple technique is widely used by home gardeners and commercial growers because it is fast, inexpensive, and produces plants that are genetically identical to the parent.
The process begins by selecting a healthy, well-established lemongrass clump that is at least one year old. Water the soil thoroughly a day before digging to soften the ground and reduce root damage. Carefully lift the entire clump using a garden fork or shovel, preserving as much of the root system as possible.
Next, gently shake or wash away excess soil to expose the roots. Using a clean, sharp knife or pruning tool, divide the clump into several smaller sections. Each division should contain at least three to five healthy stalks with a strong root system attached. Remove any dry, damaged, or diseased leaves and trim overly long roots to encourage fresh growth after transplanting.
Prepare a sunny planting area with loose, fertile, and well-drained soil enriched with compost or organic matter. Dig planting holes large enough to accommodate the roots comfortably, then place each divided clump into the soil at the same depth as it was previously growing. Space the plants approximately 50–70 centimeters apart to allow proper air circulation and future expansion. Water thoroughly after planting to help settle the soil around the roots.
During the first few weeks, keep the soil consistently moist but not waterlogged. Applying organic mulch around the plants helps conserve moisture, suppress weeds, and regulate soil temperature. Regular watering, occasional fertilization, and removal of old leaves will encourage rapid establishment and healthy new shoots.
Within several weeks, the divided lemongrass plants begin producing fresh leaves and strong root systems. As they mature, they develop into dense, productive clumps that can be harvested repeatedly for cooking, herbal tea, or essential oil production.
Dividing mature lemongrass is an effective and sustainable propagation method that improves plant health, increases productivity, and allows gardeners to create many vigorous new plants from a single established clump with minimal cost and effort.
