Landscape fabric under pine bark: when is it useful?

Permeable landscape fabric can separate soil from mulch and slow some weeds, but it should be selected according to the future use of the bed.
Suitable areas
Paths, stable shrub zones and gravel surfaces can benefit from separation.
Perennial beds
Fabric may make frequent replanting and soil improvement more difficult.
Installation
Overlap and secure strips, and create generous openings around plants.
Maintenance
Wind-blown dust can support weeds above the fabric, so regular removal is still necessary.
Summary
Landscape fabric is a supporting layer, not a complete weed-control solution.
