Use the Right One for Each Job
Flower beds & ornamental gardens→ Mulch
Uniform look, easier to work around plants, won't tie up nitrogen
Around trees & shrubs→ Wood chips
Better long-term soil improvement, deeper organic matter, economical for large rings
Garden paths & walkways→ Wood chips
Coarser texture holds up to foot traffic longer without compressing
Vegetable gardens→ Mulch (aged)
Use well-composted bark mulch — avoid fresh chips near vegetables due to nitrogen tie-up
Playground surfaces→ Neither
Use rubber mulch or engineered wood fiber for playground safety compliance
