How to Grow Tree Moss In a Tank

Choose a tank for the tree moss. Any size of fish tank is suitable for growing moss, or you can use an empty jar, fish bowl or wide-mouthed goblet or bottle. The opening should be wide enough to allow you to place the necessary items into the tank and reach in and move them around. A tank with a lid is ideal, although it can be covered with clear plastic if it does not have a lid.

Line the bottom of the container with a 1- to 3-inch layer of gravel. This will provide drainage in the tank. Level the gravel with the palm of your hand.

Place a layer of growing medium 1 1/2 to 2 inches deep on top of the pebbles. Use a growing medium that is 1 part soil, 1 part peat moss and 1 part vermiculite.

Position small stems of hardwood trees in the tank. They can be placed horizontally or vertically until you find a visually pleasing arrangement. Examples of species of trees commonly associated with tree moss include spruce, hemlock and fir.

Inspect the moss before placing it in the tank. Look for signs of disease, such as dead areas, as well as insects and their eggs.

Arrange the tree moss on the pieces of bark. Mist lightly when complete.

Cover the tank and place it in a well-lit location that is not in direct sunlight.

Remove the lid and check the soil occasionally to see if the moss needs water. Spritz the moss lightly when the soil is dry to the touch.
