Are wood chippings good for the garden?
There are lots of benefits to using woodchip: It’s 100% organic (and natural) – which gets a big thumbs up from us! It’s great at retaining water – helping your soils stay moist by “trapping” water and stopping it from evaporating, contributing to your plants’ health. One of the primary benefits of using woodchips for weed suppression is the significant reduction in weed growth. The thick layer of woodchips acts as a physical barrier, preventing sunlight from reaching the weed seeds and hindering their ability to sprout.Do not place weed barrier under woodchips. As the wood chips break down they create a perfect environment (compost) for unwanted plants to grow. I have pulled weed barrier out of landscapes where the sod, shrubs and weeds have grown right through the composted mulch and weed barrier.While they won’t eliminate weeds entirely, they act as a barrier that blocks sunlight, making it harder for weeds to grow. For best results, many people combine bark chippings for weeds with a weed control membrane underneath, which provides an extra layer of protection.
What do you put under wood chippings?
Making a wood chip path Next, rake the soil smooth to creat a nice even surface to work with. Once you are happy, lay down a weed membrane over the soil to prevent unwanted weeds growing through the wood chips. Make sure your membrane is flat and covers the entire area of your path. How to Get Your Garden Ready for Woodchips. Before laying wood chips, we recommend that you rake the soil in your garden until it’s completely flat. Then, after the bark chips have been spread in their entirety, remove any large weeds to prevent them from growing through, and give you hassle later on down the line.Sometimes known by its slightly less attractive name of “mulch”, it is exactly what its name says – chips of wood and/or bark. Bark, mulch or wood chip is a fantastic and natural addition to your garden beds.Wood chips are excellent organic mulch. A three-inch layer of mulch around your landscape beds can help suppress weeds, improve moisture retention, and stabilize the soil temperature. These benefits give your flowers and shrubs the perfect environment to thrive.The mulch also hides the soil, making it more difficult to know when to water. Also, wood chips break down and must be re-applied every year or two. Wood chips can also harbor insects that may attack plants, including slugs, earwigs, sowbugs, and ants.
Do wood chips turn to dirt?
It’s important to note that wood chips will decompose over time, requiring periodic replenishing. This gradual breakdown is beneficial for long-term soil health but means you’ll need to maintain your desired depth for pathways and garden beds. Before laying wood chips, we recommend that you rake the soil in your garden until it’s completely flat. Then, after the bark chips have been spread in their entirety, remove any large weeds to prevent them from growing through, and give you hassle later on down the line.You can use wood chips to add organic material to soil. The process will take four or more years.You don’t want to plant into the chips directly, but into the soil beneath. I usually put down only 6 to 8 inches of chips which shrinks down to 4 to 5 inches over about a year.One thing that occurs when wood chips are tilled into soil is the soil microbes start to break down the wood chips, and in doing so scavenge a lot of available nitrogen in the soil to do that job. It’s nothing devastating, it’s only temporary, but likely at least one part of why your garden did not perform well.
What plants do not like wood chips?
There are some species that tolerate excessive mulch better than others. Some of the worst effected plants are grassy plants (iris, daylilies, liriope, etc. Indian Hawthorn, Azaleas and Loropetalum. Mulch with fine grade material has very poor airflow, and will remain wet for long periods, causing many problems, including crown rot. It is bad to have low airflow and constant moist conditions in the top 50mm to 100mm around the crown of plants.Landscape fabric under mulch may seem like a smart weed-control solution, but it often causes more harm than good. Over time, it blocks water and nutrients, damages roots, and traps decomposed mulch—leading to more weeds. Instead, rely on natural mulch, proper depth, and routine care.The soil may never dry, creating dire conditions for some plants.

How long do wood chippings last?
Wood chips will take an average of 2 to 4 years before any refresh is required. The real-time duration depends on a number of issues: Climate – Wood chips decompose faster in hot, humid areas. Dry conditions cause them to last longer. Garden Beds: Soil Enhancement: As wood chips break down, they add organic matter to the soil, improving its structure and nutrient content. Moisture Management: A layer of wood chips on garden beds helps retain soil moisture and regulate temperature.Disadvantages of wood chips include their potential to temporarily reduce soil nitrogen levels as they decompose, attract termites, and their slow decomposition rate, which may not be ideal for soils needing quick nutrient turnover.
Can I put soil on top of wood chips?
Many people worry about the woodchips leaching nutrients from their soil. This isn’t much concern when adding on top, but can be an issue if you’re mixing them into the soil. For me, I needed to use compost and blood meal to add nitrogen back into my soil. Once you’ve established which types of woodchip you have and want to use, simply spread a layer of that woodchip across the areas of your garden that you’re “feeding” and start reaping its wonderful benefits. A deep layer of woodchip (between 3 – 5 inches) over your soil does a good job.
