I mulch everything...When I cut the pampas back I shred it as well as the leaves small limbs that are around.. I also use the grass clippings and composted manure (we have cows..).. All of these things provide protection and give back to the earth... It may not sound as aesthetically pleasing as some of the commercial mulches but it darkens with age and seems to dissapear as the plantings mature..
