Excellent for small bowls or ponds, provided the water is kept still.

Division

  1. 1. Scoop a small portion of the plants from the surface.
  2. 2. Place the portion into a new container with nutrient rich water.
  3. 3. Ensure the water remains still to encourage rapid growth.

Keep the water surface clear of debris to allow maximum light penetration for growth.
