Is it bad to mulch every year? A layer of mulch on a planting bed helps suppress weeds, retain moisture, and moderate soil temperature. But the biggest problem we see today is too much mulch. When added year after year, mulch can actually harm plants by creating a layer that doesn't decompose and doesn't allow root growth.

What do you do with last year's mulch?
