You can leave the stem plant bottoms planted. They will grow new shoots from the leaf nodes. Done properly you can get a nice bushy effect. Sooner or later the bottoms will get so ragged looking that you will want to remove some of them.
I generally just use my hands and rip hunks of moss off when it starts getting over grown looking. You could use scissors as well.
From where the sun now stands, I will fight no more forever.
