If you’re looking for the best material to use in gardening, one of your top considerations is likely between wood chips and mulch. Both can help control weeds and keep moisture in the soil – however, there are key differences that could make one choice a better fit than the other. In this blog post, we’ll provide an overview of how choosing either wood chips or mulch can impact garden health and maintenance, effectiveness in weed suppression, cost efficiency, ease of installation—and ultimately which will be better suited for growing a healthy garden!
Wood Chips vs. Mulch: What is Mulch?
Mulch is an essential material for any garden, and it can provide significant benefits for both the soil and plants. It is a layer of organic or inorganic material spread on top of soil that can conserve moisture, suppress weed growth, and improve the soil’s fertility. Organic mulch includes materials such as leaves, straw, wood chips, and bark, while inorganic mulch includes materials like river rocks, gravel, and crushed shells. [1] It decomposes over time, providing nutrients to the plants and creating a healthy environment for microorganisms that break it down.
Applying mulch is easy and cost-effective, making it an excellent addition to any garden. By using mulch, you can cut down on watering and weeding your garden and enhance the soil’s health, creating a more vibrant and thriving garden.
Types Of Organic Mulch
Organic mulch is the most popular choice for gardeners, and there are a few different types to choose from.

It will also give beneficial microorganisms time to populate the chips, which can help enrich soil as they decompose. Waiting this amount of time also helps reduce any potential weed problems from dormant weed seeds that may be present in the wood chips when purchased.
Why are My Plants Dying After Mulching?
If your plants are beginning to die after adding wood chips as a mulch, it could be due to nitrogen deficiency. As the wood chips decompose, they will use up the available nitrogen in the soil and cause it to become depleted. To help prevent this issue, mix some organic fertilizers with the wood chips before applying them as a mulch. This will ensure that your plants have access to all of the necessary nutrients for healthy growth.
Why Is Organic Mulch Good For My Garden?
Organic mulch is beneficial for your garden as it helps regulate the soil temperature, reduce weed growth, and add organic matter to the soil. By keeping the soil cool in summer and warm in winter, organic mulches help keep plants healthy and thriving all year round.
In addition, they can act as a slow-release fertilizer that will provide essential nutrients over time. Finally, organic mulches like wood chips are biodegradable and eco-friendly, making them an excellent choice for any garden.
If It Breaks Down, Does That Mean I Need To Replace Wood Mulch In My Yard Every Year?
No, it is not necessary to replace your wood mulch every year. Wood chips will break down over time, but this process can take several years depending on the type of wood used and environmental conditions. When the wood chips do become too broken down, you can simply add a new layer of mulch on top of the existing one without needing to completely remove and replace all the old material. This way, you can keep topping up your mulch each year to maintain its benefits without having to start from scratch.
What’s the Difference Between Compost And Wood Mulch?
Compost and wood mulch are two types of soil amendments that can help improve soil fertility and moisture retention. Compost is organic material such as food scraps, yard waste, and manure that has been decomposed by microorganisms into a nutritious soil amendment. Wood mulch is made up of finely ground wood chips or bark that helps to add nutrients to the soil while also helping to suppress weeds. The main difference between compost and wood mulch is their nutrient content. Compost contains high levels of nitrogen, potassium, phosphorus, calcium, and other essential micronutrients for plant health. Wood mulch does not contain any significant amount of macro-nutrients but instead provides protection from temperature extremes and prevents weed growth. Compost is best used as an amendment to existing soil systems, while wood mulch can be used as a top dressing for beds and pathways. Both compost and wood mulch can help improve soil fertility and moisture retention. In addition, both are excellent at promoting the growth of beneficial microorganisms in the soil. However, each should be applied differently depending on what your specific gardening needs are.
