How and when do you prune Pampas grass--or do you?
Yes you do. Pampas grass, along with all ornamental grasses should be cut back before new growth begins. Pampas grass can be tough to cut. Some folks use a chain saw, (reversing the blade direction seems to make it easier), while others use hedge trimmers. You won’t be able to cut it flush with the ground, but taking off the majority of the old foliage will give you a healthier and cleaner plant. Do it every year in late February to early March.
