mulch over exposed roots
Under a large sugar maple, where the lawn has died and the roots showing on the surface, I saw where our HOA has simply put a basic shredded bark mulch maybe an inch thick over it all rather than trying to plant grass.
At first I thought this was bad, then I figured, well, as long as it's no deeper than natural leaf litter would be, why not?
Is this an acceptable thing to do instead of burying with soil (Bad I know) or the futile attempt at planting grass?
How deep of mulch is OK? And should you remove old mulch each time you remulch or just add on top as the old stuff decomposes? I'd worry about it covering the roots too deeply.
