Terrariums are a great way to make any space a little greener, and even someone with a brown thumb can create and maintain a terrarium. The plants are kept under glass in their own mini-ecosystem, so you don't have to worry about watering.
Things You Will Need
~bell jar and some kind of base/ a lidded glass jar
Arrange rocks on your base in an attractive fashion, and add some activated charcoal. The activated charcoal will prevent the closed-up environment from developing a funky smell. Next add some soil to give your moss a surface to grow into and draw moisture from. You don't need a thick layer of soil--just enough between the rocks for the moss to sit on.
