- Plant the stem cutting in a substrate, such as gravel or sand, and ensure that at least one node is buried in the substrate.
- Keep the substrate moist and place the cutting in a well-lit area.
- Within a few days, roots should appear from the buried node and new shoots should emerge from the top nodes.
Propagation through runners
Limnophila gratioloides can produce runners, which are horizontal stems that grow along the substrate and produce new shoots. Runners can be used for propagation and can produce new plants quickly and efficiently. Here are the steps to follow for successful runner propagation:
- Choose a plant that has produced runners and wait until the runners have produced new shoots.
- Gently clip the runners and new shoots away from the parent plant and plant them in a substrate.
- Ensure that the new shoots are covered with substrate and keep the substrate moist.
- Place the new shoots in a well-lit area.
- Within a few days, roots should appear from the buried nodes and the new shoots should grow into mature plants.
Propagation of Limnophila gratioloides is easy and can quickly produce new plants for your aquatic garden. Whether you choose to propagate through stem cuttings or runners, ensure to maintain the proper environment and substrate to keep the plants healthy and thriving.
