I'm in Zone 4, so I'll bring in my grass for the winter. Do I cut it back when I bring it in or in the late winter?

If you're bringing it indoors, then you can cut it back and place it in a somewhat darkened area to overwinter, watering only when extremely dry. Keep in mind that overwintering this grass doesn't always work and although it's labeled perennial, it is actually considered a tender perennial, meaning it will not survive outside its growing zone (cold temps) and is often treated more like an annual in these areas.
