Moss is nature's carpet and it is an easy plant to care for. In this video, I show how I made a live moss tray for decoration and a howto grow moss in a pot.
You can find moss outdoors in wooded areas or even in the city. Moss grows in most climates and should be no problem to find growing in shaded areas or on trees.
Moss art, tray, or wall can grow indoors with no problem. To help your moss grow you need a few things: An acidic environment or soil, compact soil, an area with indirect sunlight, and moisture.
Mist your most as needed and make sure it does not dry out. Once your moss is established in its new environment it will begin to grow. Moss grows very slowly so after a couple of months if needed and can trim the moss into the shape you prefer.

Let me know if you guys have any tips for gathering and caring for moss :)
