Kokedama is also known as "Poor Man's Bonsai" and is extremely trendy right now. Originally from Japan, these bonsais have their roots wrapped in moss instead of a pot. They can be hung or placed on a dish.
Simply place your kokedama in a saucer of water to soak for 15 minutes, then wring out the excess water, and hang up back up or place back on it's plate. Repeat when required.
