Christmas moss is semi-aquatic and as there are no roots so it is a little bit difficult for the moss plant to penetrate into the soil or wood.

Tank requirements – Proper light setting is important in this method, the tank should be filled with highly nutritious soil than normal soil for 2 to 3 cm thick from the ground level.

Spray like the mist and maintain the humidity by covering the top of the tank with a plastic cover. Place them in soil and cover the tank under the light. The plastic cover should only be opened and closed once a day.

In 30 to 45 days more patience is needed as it has week roots.

This simply means that as the Christmas moss stems break off and fall to the substrate, they grow into their own plant.

Using sterilized scissors, take cuttings from fully grown Christmas moss. Place these cuttings back into the substrate elsewhere and they’ll soon develop into their own plant. The newly planted moss in few days they would start producing roots.

Key points to remember when you propagate

  • Each cutting should have at least three leaves so that the new plant can photosynthesis
  • Don’t take a lot from the original plant as it will struggle to survive.
  • You don’t need to create any special conditions in your tank for propagation, but the plants will grow best when the water is clean and has the required amount of light, nutrients, and CO2.
