Wood Chips including Cedar Chips are a great way to have healthy plants.
For many of our non-lawn garden designs, we opt for cedar chips instead of the traditional dark brown bark dust as a top dress. While some prefer the more conventional look of bark dust, cedar chips offer distinct advantages: they last for years saving the labor of applying a new layer every year. Cedar chips and wood chips conserve moisture during summer, and provide excellent insulation through winter. I love NW Play Fiber from Grimms Fuel for cedar chips that last for years and because of how they are cut, work better for paths too.
Why are Multi Species Wood Chips so Popular in Portland?
Multi tree species wood chips (often called arborists chips), are advantageous to soil, breaking down and supplying a more diverse group of beneficial bacteria than cedar chips. However they last only a year typically. Chip Drop, is a service that delivers mixed species wood chips for cheap. However, it’s critical to understand that this donation-based service can come with some important caveats—there might be soil, rocks, or even debris (garbage) in the mix. It’s not a criticism of the affordable service, but rather something to keep in mind when deciding if it’s right for your garden.
If they chip trees by a road, some garbage on that road might come along with your wood chips. Also the minimum amount they are willing to drop might be six times what you can use so check it out carefully. Still using what is otherwise waste product is perfect for environmental reasons. In our world today finding something that is fully reusable is rare. Just check out their service carefully to be sure you want what they offer.
Applying Wood Chips to Planting Areas

Wood chips play a crucial role in insulating the soil, retaining moisture, and gradually breaking down to enhance soil structure. When applying mulch, aim for a 2-inch layer, being careful not to bury your plants—spread the mulch around them, not over them. If you’ve already top-dressed your garden with a 2-inch layer of wood chips or bark dust at the time of planting, don’t add more chips until it begins to break down. However, it’s wise to keep your wood chips topped up yearly to 2 inches to help with weed control and maintain the health of your garden. People often apply wood chips 6″ deep for paths. Cedar chips last several years, wood chips are much more short term.
