Now that your ornamental grasses are neatly bundled, it's much easier to take your pruning shears and prune the grass back at ground level. Because the tape is holding the grass blades in place, you can lean the ornamental grass bundle away from the base as you cut, to make cutting easier.
If your ornamental grass is well established, you may prefer to use a power hedge trimmer to do the job. Either way, pre-bundling the grass will make it an easier job than grabbing handfuls of grass blades and hand pruning.
