Answer: Unfortunately, there is not a lot you can do to protect this plant in colder areas with any kind of certainty of success. You could try mulching heavily around the perimeter (not over top of the crown). Some gardeners report success by bending and tieing the top grassy foliage over top of the crown in such a way that it will shed water and snow. You could compare this to a haystack in the way it should work. This would limit moisture collecting and freezing in the crown area and would also provide a certain amount of insulation for it. Alternatively, since it grows so well, you could consider replacing it each year and growing it as an annual. Good luck with your pampas grass!
