What Wood Chips Should I Avoid?
When choosing wood chips for your garden, you’ll want to consider what you use carefully.
The wood chips break down, creating a mulch for your plants. However, not all plants will love every type of wood chip.
Some types of wood chips release chemicals into the soil that are toxic to some plants.
For example, eucalyptus, black walnut, and the tree of heaven bark can kill young plants or even prevent them from sprouting in the first place!
If you want your garden to thrive, you need to ensure that your wood chips don’t leach allelochemicals into the ground.
These chemicals are what become the toxins that can harm young plants.
Allelochemicals include any chemical made by a living creature, but they have adverse effects when interacting with other organisms.
Because of this, you must avoid wood chips that contain these harmful components to keep your garden thriving.
Why Shouldn’t I Use Eucalyptus Chips?
Eucalyptus releases allelochemicals into the soil as it breaks down, causing significant damage to plants!
The chemicals can cause plants to turn yellow or even die.
These chips also have a unique effect on soil- they remove nitrogen from the ground!
As a Gardener – You may already know that nitrogen is an essential part of your soil for growing a healthy and abundant garden.
Eucalyptus is also toxic to many plants and creatures living in the soil. Overall, you shouldn’t include it in your garden!
Why Shouldn’t I Use Black Walnut Chips?
Black walnut chips are very bad for crops!
The bark contains juglone, which is toxic to a variety of plants, including:
If you’re growing any of those crops at home, you’ll want to make sure that you avoid using juglone.
Black walnut wood can easily harm these plants, stop their growth, or cause them to wilt!
You’ll need to choose other types of wood chips instead.
Why Shouldn’t I Use Tree of Heaven Chips?
Tree of heaven wood chips also emit high amounts of allelochemicals into the ground.
These chemicals can kill plants or prevent young seedlings from sprouting fully.
Even when the tree of heaven is alive, its roots can kill nearby vegetation.
What Wood Chips Can I Use Instead?
Luckily, there are plenty of other wood chips that you can use instead of these!
You’ll want to consider your location and choose a local option.
That way, you can receive more benefits and have a sustainable source of wood chips.
Here are some alternatives that will benefit your garden greatly:
- Pine bark mulch
- Arborist wood chip mulch
Pine bark mulch that’s finely ground is best.
It’s very light and airy, allowing young plants to emerge from the ground easily. It also conditions the soil and adds more nutrients to it as it breaks down.
However, you’ll need to keep the chips on top of the soil. That way, they don’t absorb the nitrogen there.
For Arborist Mulch – They are natural and don’t contain any dyes. These mulches are great for gardens, and you can usually find them locally.
Some tree removal services will even offer to bring them for free!
In short, you do have plenty of options for wood chips!

Why Should I Use Wood Chips in a Garden?
Wood chips, or mulch, have a variety of uses in a garden- especially if you’re growing your own vegetables!
Veggie plants love many nutrients that wood chips add to the soil, helping them grow. Plus, there are more benefits to consider.
Mulch Holds in Water
Seeds and young plants require a lot of water!
Adding mulch provides a top layer to your soil, holding in more water for longer periods.
Since the water won’t evaporate into the air as easily, your plants have more time to drink it.
You also won’t water your garden as frequently because of this.
Mulch Enriches Soil
Organic mulch also enriches your soil in a variety of ways.
It supplies the soil with more nutrients as it breaks down.
Your plants take in the nutrients, allowing for fuller, healthier plants that produce more vegetables.
Much Stops Weeds
