  • Natural color retention, unlike some wood mulches.
  • Ideal for acidic soil-loving plants like pine bark nuggets.
  • Shape maintenance, no compaction.
  • Wide availability.


  • Suited for stationary areas like tree bases and shrub beds.
  • Buoyant in water, best for level ground.
  • Prone to wood-loving pests like termites.

Bark Mulch

Made from the aged bark of hardwood (oak, hickory, etc.) and softwood (fir, pine, cedar, etc.) trees, bark mulch can be shredded, sometimes double-shredded, offering a finer texture.


  • Easily accessible.
  • Varied wood sources provide natural color choices.
  • Faster decomposition due to shredding.


  • Hardwood bark mulch can elevate soil alkalinity, challenging acid-loving plants.

Understanding bark’s essence empowers gardeners. From nuggets’ steadfastness to mulch’s color array, each variety brings nuances to your garden’s canvas.

A Pacific Northwest Favorite

Bark dust, a newcomer to some, but a staple for Pacific Northwest gardeners and landscapers, emerges on the scene.

Bark dust, typically crafted from the bark and wood of cedar, fir, pine, spruce, and hemlock trees, is ground into fine particles and granules. Notably, it’s renowned in the region for its versatile utility.


  • Varied wood sources offer a natural spectrum of colors, enhancing garden aesthetics without artificial dyes.
  • Ideal for providing a soft, splinter-free surface in children’s play areas.


  • Although DIY-friendly, its fine texture might pose challenges for certain applications.
  • Widely available in the Pacific Northwest, relatively less common in other parts of North America.

Bark dust’s subtle splendor and practical advantages make it a beloved choice for landscaping and design in the Pacific Northwest and beyond.

A Closer Look at Wood Chip Mulch

Wood chips, an organic marvel, arise from both hardwoods and softwoods, offering a versatile option for mulching.

Wood chip mulch often comes at a more affordable price point compared to shredded wood or bark alternatives. For those in the know, acquiring wood chips can be cost-free through resourceful inquiries and locations.

Be mindful that free wood chip piles might include various tree parts: chipped trunks, bark, branches, leaves, needles, and even pine cones. Such diversity stems from tree trimming and removal processes, which facilitate easier transport and disposal.


  • Cost-effective: Obtain inexpensively or for free.
  • Aid local landscaping and tree trimming businesses by reducing their gas and landfill expenses when you utilize their excess wood chips.


  • Lack of control over the composition of free wood chip piles.
  • Fresh wood chips can temporarily deplete nitrogen from soil and plants during the early stages of decomposition. Hence, favor wood chips for pathways rather than flower or vegetable beds.

Unravel the potential of wood chip mulch, an affordable and environmentally conscious choice that adds both aesthetics and benefits to your landscape.

Embracing Eco-Friendly Choices
