Organic mulch improves the soil by providing nutrients and improving texture. While many organic mulches are available, some are not well known like others.
One of the lesser-known organic mulches is pecan shell mulch. This mulch is a result of breaking down pecan shells and can be used to protect your garden or landscaping plants from the sun, prevent weed growth and even improve soil fertility. So, should you use pecan mulch?
What Are Pecan Shells?
Pecan shells are the outer covering of nuts from the pecan plant. Before eating pecan nuts, you must remove the outer husks covering them. The outer husks are what make up the pecan shells.
Pecan shells have many uses, including being used to light fires and as firewood. Perhaps the best utilization for these husks is making mulch.
Since the shells are rich in nutrients and elements that are good for the soil, there has been an increase in the use of pecan shells as garden mulch.
Can You Use Pecan Shells as Mulch?
You can use pecan hulls for mulch in your gardening or landscaping activities. These shells have a great-looking reddish-brown color and provide a protective layer to your garden soil.
Pecan mulch also provides an underfoot for your garden that is crunchy and very good in improving soil fertility.
How Do You Prepare Pecan Shells To Be Mulch?
Now that you understand what pecan shells are and can be used as mulch for your garden, the next logical step would be to know how to make the mulch. Preparing pecan shell mulch isn’t difficult. It can be done as a DIY project.
Always use dry or already composted shells for your pecan husks as mulch. Fresh shells tend to attract squirrels and other nut-loving creatures to your garden.
Here are the steps for making pecan husk mulch for your garden:
The first step involves getting the pecan shells. You can do so by collecting husks from the pecans you eat. However, for most people doing this would take a long time to have enough shells to prepare a mulch. We recommend purchasing pecan husks.
When you have enough shells, you must prepare them for mulching, depending on your use.
If you intend to mulch the flowers in your garden, you may consider putting the shell in a grinder (a coffee grinder will do) to break them into tiny pieces.
Use the shells as they are if you intend to mulch a large area around your garden.
If you like, you can put the shells in your compost pile before using them. Wait until they break down before using them as mulch in your garden. Composting might take a while, but it’s worth it.
How Do You Use Pecan Shell as Garden Mulch?
There are two options here:
- If you grow plants in pots or bags in your garden, you can spread the pecan mulch on the surface around the plant. A 1-inch-thick layer would be enough to protect the soil around your plant from the sun and prevent loss of moisture.
- If you have planted directly on the ground, spreading a 2 to 3-inch layer of mulch is advisable to protect the soil and plant.
Due to its appealing red-brown color, the mulch will make your garden more aesthetically pleasing in addition to all its other benefits.

Termites can be a nuisance, especially for gardeners who use organic mulches. Organic mulches attract termites as they provide nutrients the insects are looking for.
Pecan husks attract termites simply because they provide a layer of protection under which the insects can make their home.
