Cut the meristem tip of the Polystachya parva Summerh. and plant in the nutrient medium. The meristem tip will keep growing, and you can separate it to form a new plant. Meristem culture ensures that the new plant will be disease-free and will produce the same characteristics as the parent plant.
Seed Sowing
Seed sowing is another propagation method for Polystachya parva Summerh. It is the least preferred method because orchid seeds require a specific environment to grow. The seeds need to be sown in a nutrient-rich medium with a specific pH, and the temperature and humidity levels need to be carefully monitored.
