Wood chip, especially when bought by the bulk bag, can be a very cost-effective type of decorative aggregate. As a long-lasting material, its durability means less frequent replenishment, saving money and time in the long run.

Wood Chip Mulch & Topsoil

Wood chippings can act as an effective mulch layer, providing protection to plants and the topsoil underneath. However, unless they are composted wood chip, they can be very slow to break down, especially when first laid and fresh. Therefore, when using fresh wood chips as a garden mulch, it is advisable to consider integrating a layer of bark mulch or topsoil for the additional nutrients your plants need.

Organic vs. Treated Wood Chip

While natural wood chippings are popular for their organic appeal, some opt for treated types. These are mostly utilised for installations where longevity is a primary goal, such as for driveways or garden paths. Treated chippings can be more resilient and hard-wearing, but is important to ensure any treatment is safe for your intended use.
