Tap into your inner hairstylist as you lean over the fountain grass and comb or rake your gloved fingers through the middle of the clump, grabbing all loose and dead or dried-up hairs (blades/branches). Comb through the entire grass, and shake it occasionally to get out more dried plant material. You may end up with a good-sized pile of the dead stuff, which you should pitch into a portable container as you go along. Otherwise, it's a real chore to clean up all of those blades and clumps of grass
after you've done the pruning and grooming.
So far, so good.
