This listing is for: 1 golf ball size portion of Java moss. Java moss is a very easy to grow plant, great for both experienced and beginner plant keepers. Java moss will have some brown pieces mixed in with the green. Expect this, it is normal. Java moss is grown out of the water originally, pieces that don't receive light on the bottom will be yellow/brown so there will be some brown on the bottom in with the green moss. Place the moss around whatever you would like to attach it to and then use thread to wrap around the item to lock the moss on so it doesn't come off and float all over the tank. Give it time to grow in.
