The warm weather of spring and summer reminds us of birdsong, fresh vegetables, fragrant native flowers, and…. brush piles. Most people relegate brush and slash to be burnt, but this is a tremendous misuse of free organic material.
Brush, also called slash, is extra branches, leaves, sticks, and other woody/leafy material left over after cutting vegetation. It is created after logging operations when trees or bushes are trimmed, or after a natural weather event that downs a tree or tree limb.
For many homeowners, brush piles are seen as a nuisance because it makes the yard look “untidy.” However, since leaves and limbs hold much of a tree’s nutrients, they are actually tremendously valuable sources of organic matter.
Burning a brush pile is a huge waste of resources! Also, you’ll probably annoy your neighbors, and then they won’t like you. Just don’t do it.
Instead, try one of these much better and more resourceful alternatives for your brush pile!
Here are 5 Things To Do With Your Brush Pile (besides burning it).

1. Hugelkultur Mounds
Hugelkultur mounds are the best option to use your brush for. They are also the biggest provider of the most simultaneous and diverse benefits to your property on this list.
If you’re new to permaculture or just happened to stumble across this blog post, you may be wondering “what the heck is a hugelkultur mound?”
In short, it is a layered mound comprised of all natural organic components. The base layer is usually large decomposing logs, topped with smaller twigs and branches, topped with smaller organic matter, such as leaves, grass trimmings, or straw. Finally, it’s topped off with compost and topsoil, creating a nutrient-rich pile that decomposes over time.
To learn more about the specifics, read our article What Is Hugelkultur Gardening?
The benefits of using your brush in a hugelkultur mound instead of burning it are twofold and will last many years.
1. You can immediately grow vegetables on your mound. You certainly can’t do that with a burned-up brush pile! Additionally, you will be able to continue planting annual produce on your mound for years to come as the mound decomposes.
2. When the mound is done decomposing, you are left with a very rich, nutrient-dense humus that can be spread to other parts of your property. This is the best way to improve soil health.
Imagine building a hugelkultur mound every year with your brush pile (of course, if space allows), and eventually never having to purchase soil from outside sources again. That would be awesome!
2. Create Shelter For Wildlife
Did you know wildlife thrives when there is available understory to use as shelter? Brush piles are an excellent way to provide this shelter if you want to attract small mammals and birds to your yard.
According to Choose Natives, there are three elements a brush pile provides to wildlife:
1. Sanctuary. Brush piles create a sanctuary for our wildlife. Birds, salamanders, snakes, turtles, small mammals (and more!) all need a helping hand, especially in our stripped-down suburban areas. A properly built brush pile provides a place for our creatures to hide from their many predators.
2. Shelter. In times of extreme weather, a brush pile is a perfect shelter. In winter it’s particularly vital for protecting our birds. If your property is void of mature evergreen shrubs and trees that birds need for protective cover, evergreen foliage placed over a brush pile during the winter months will create a dry interior birds can safely roost in.
3. Snacks. Many insect species are attracted to the decaying wood and will make it their home. Insects found in brush piles are an additional source of protein-rich food for woodpeckers and other bug-eating animals.
3. Repair Damaged Soil
Using brush is a great way to repair damaged soil – it acts as a kind of oversized mulch.
Did you know that the leaves and branches are the most nutrient-rich parts of a tree? The trunk is primarily dead tissue and contains proportionally fewer nutrients per unit of mass compared to branches and leaves.
As it decomposes, these leaves and branches return their coveted nutrients back to the soil.
We recommend evaluating your yard to see what areas need a little help in the “nutrient department.” Cover these areas with a layer of brush, and leave it there! Not only with the laid-out extra branches and leaves add important nutrients to the soil as it breaks down, but they will also serve as a shelter from the elements for already damaged ground.
With trees gone or at least less dense due to clearing, more rain gets to the ground, and brush will act as a stabilizing component for the soil. It also shades the ground from harsh, direct sunlight which prevents the burn-off of nutrients as well as providing a moist microclimate for new growth. Slash also, much like mulch, offers a degree of insulation for the ground below during the chill of winter, which will help plant growth get off to a better start in the spring.
Now, we know that most people don’t want random brush just thrown about the yard, so we have another suggestion to make the process speed up. Seed a nitrogen-fixing plant, such as clover or some native wildflowers under your brush. This will help the brush turn into a collective part of your yard as the cover plants grow out through the pile, while simultaneously taking nutrients from the brush as it decomposes.
4. Build A Gardening Structure
Brush usually contains a mix of sturdier woody branches, and smaller twigs, sticks, and leaves. If you have enough sturdier woody branches, consider building a structure out of them for either decorative or utilitarian purposes.
Below is an example of a bench made out of some fallen limbs (and here are the design instructions, if you need guidance).

5. Turn Into Woodchips
As a last resort, converting your brush pile into woodchips is still a more preferable option to just burning it.
Woodchips are great to use as mulch in your garden, to bulk up a raised bed, to create paths in your yard, or to cover a kid’s play area. These are all better options than burning simply because the free organic matter touted above is still located on your property and will get a chance to break down and put its nutrients back into the ground.
You can rent a woodchipper from a local hardware or equipment rental store. Some places have daily and weekly rentals. You could also buy one for yourself if you feel the need and projected use outweighs the cost.
