Question: Our front yard has a very steep slope in the front which is hard to maintain. We plan to cover the bare soil in the area with 3 inches of mulch and plant a groundcover. Should we lay down landscape fabric first?

Answer: Since you want groundcovers to spread, don't use landscape fabric, since this will keep them from spreading. If the slope is truly steep and in danger of eroding, consult with a landscape architect for assistance in designing a suitable retaining wall or series of terraces.
