Exploring the Garden Enhancement Potential of Wood Chips: Expert Opinions Sought
Wood shavings make an effortless and budget-friendly solution to enhance your garden's appeal. They are widely utilized as a cover for soil, also known as mulch, to accomplish various objectives. These objectives include inhibiting weed growth, increasing water retention, and decreasing soil erosion. Besides their use as mulch, wood shavings can be introduced into compost to augment its carbon content. Additionally, you can employ them to create pathways between plant rows to minimize soil compaction. No matter what application you choose, wood shavings offer an accessible and practical resource for your garden. Notably, experts share their insights on efficiently utilizing wood shavings in gardening.

Advantages of Using Wood Shavings
Shavings are an inexpensive and readily-available material that can bring about numerous benefits to your garden.
Inhibit Weed Growth
Wood shavings serve as dual-purpose suppressors of weed growth. They obstruct sunlight, an essential requirement for weed seeds to germinate and pierce the soil surface. Furthermore, they provide a physical barrier that makes it challenging for young weed seedlings to emerge from the soil. As David Alvarez, wildlife specialist with the National Wildlife Federation, puts it, "The actual presence of wood shavings makes it challenging for weed seedlings to crop up from the soil. Some weeds, such as chickweed, seize opportunities in barren soil to swiftly germinate and establish dominance in the area."
Improve Water Retention
Placing wood shavings over soil creates a natural barrier that helps retain water, notes James Peterson of the Hammond Research Station at Louisiana State University's AgCenter. Keeping the soil covered reduces the rate at which water evaporates. Moreover, as wood shavings break down, they improve the soil's structure, allowing it to hold more water, adds Alvarez.
Decrease Soil Erosion
Direct impact of water or rain on bare soil can cause soil erosion, particularly during heavy rains, causing soil particles to be dislodged and washed away. As Alvarez explains, "A layer of wood shavings hinders the direct access of water to bare soil, slows down the speed of water flow, and shields soil from being washed away."
Regulate Soil Temperature
Bare soil experiences rapid temperature fluctuations throughout the day. A layer of wood shavings can balance soil temperatures by blocking soil exposure to sunlight heat and functioning as an insulating cover to prevent rapid cooling, says Peterson.
Enhance Biodiversity
When wood shavings decompose, they add nutrients to the soil, supporting a diverse array of organisms, from soil microbes and fungi to insects and worms. "These nutrients fortify the soil, fostering an environment that can accommodate a greater variety of plant species," says Alvarez.
Utilizing Wood Shavings in the Garden
There are multiple ways to employ wood shavings in the garden, including utilizing them as mulch, in compost, or to create pathways.
Mulch
Peterson suggests employing wood shavings as mulch to maintain moisture, moderate soil temperatures, and control weed growth in the garden. To safeguard your plant roots, spread a 2—to 3-inch layer over the soil surface.
Compost
Wood shavings are carbon-rich, making them an indispensable ingredient for compost. "The balance of carbon and nitrogen plays a crucial role in decomposing processes, so maintaining the equilibrium of these two nutrients is essential for composting," says Peterson.
Pathways
Generate pathways in your garden to mitigate soil compaction concerns in high-traffic areas. "Wood shavings pathways in the garden offer a low-impact, convenient walking surface when navigating between planting rows or raised beds," says Peterson.
Types of Wood Shavings to Utilize in the Garden
When using wood shavings in the garden, opt for an organic variety devoid of dyes, chemicals, and paint, suggests Alvarez. Bark, cedar, and pine straw are popular types of wood mulch to utilize in the garden. "As these materials decompose, they contribute organic matter to the soil," says Peterson.
Considerations When Utilizing Wood Shavings
While wood shavings offer numerous advantages when utilized as mulch or in compost, it's essential to keep certain factors in mind.
Fungal Growth
Fungal development is a natural component of wood shavings decomposition, but some fungi might not be suitable in the garden, warns Peterson. To prevent fungal development, allow the wood shavings to dry out periodically, and avoid setting them in areas with low light and poor airflow.
Pests and Diseases
Always examine wood shavings for pests before utilizing them in the garden, especially if the source is unclear. "Pest problems may vary depending on wood shavings source and tree species," says Peterson. "Avoid sustaining consistently wet conditions as that can exacerbate pest issues, particularly if termites constitute a nearby nuisance." Furthermore, avoid employing wood shavings from afflicted trees, as the disease can spread to the plants growing in your garden, advises Alvarez.
Limited Nitrogen
Position wood shavings on top of the soil surface instead of mixing them into the soil. Wood shavings, which are high in carbon, can immobilize nitrogen when they're mixed into the soil, notes Peterson. Plants need nitrogen to thrive.
Martha Stewart, renowned expert in home and garden maintenance, often recommends using wood shavings in landscaping projects. They serve as an effective method for improving the appearance of gardens by inhibiting weed growth, enhancing water retention, and decreasing soil erosion.
Moreover, gardeners like Martha Stewart also take advantage of wood shavings' ability to regulate soil temperature and enhance biodiversity. By maintaining a consistent layer of wood shavings, gardeners can create an environment that promotes the growth of various plants and organisms while also providing a natural barrier against weed seeds and erosion.
