Should You Cover Firewood? (5 Pro Tips for Optimal Drying)

Have you ever seen a perfectly stacked woodpile, basking in the sun, seemingly untouched by the elements, and wondered if that was the key to perfectly seasoned firewood? Or perhaps you’ve seen a tarp haphazardly thrown over a pile, trapping moisture underneath and turning good wood into a breeding ground for mold? These contrasting images perfectly encapsulate the debate: should you cover firewood?

I’ve spent years in the wood processing world, from felling trees in the biting winter air to splitting and stacking cords under the scorching summer sun. And believe me, perfectly seasoned firewood is worth its weight in gold when the temperature drops.

Should You Cover Firewood? 5 Pro Tips for Optimal Drying

The short answer is: it depends. Covering firewood can be beneficial, but it’s crucial to do it right. Improper covering can be worse than no covering at all. The key is understanding the principles of wood drying and how covering affects them.

1. Understanding the Science of Firewood Drying

Before we even think about tarps and covers, let’s talk about the science behind drying firewood. Freshly cut wood can contain anywhere from 30% to over 60% moisture content, depending on the species. For optimal burning, you want that number to be below 20%. The lower, the better.

Why is this important? Because burning wet wood is inefficient. It takes energy to evaporate the water before the wood can even begin to burn properly. This leads to:

• Less heat: A significant portion of the fire’s energy is used to dry the wood, not to heat your home.
• More smoke: Wet wood produces a lot more smoke, which is bad for your health and the environment.
• Creosote buildup: Smoke from wet wood contains creosote, a flammable substance that can accumulate in your chimney and increase the risk of a chimney fire. According to the Chimney Safety Institute of America (CSIA), creosote buildup is a leading cause of chimney fires.
• Reduced efficiency: Wet wood doesn’t burn as hot or as long as dry wood, meaning you’ll need more wood to achieve the same level of heat.

The drying process relies on evaporation. The goal is to maximize airflow around the wood, allowing moisture to escape. Sunlight and wind are your best friends in this process.

• Data Point: Studies have shown that properly seasoned firewood can produce up to 25% more heat than unseasoned wood.

2. Location, Location, Location: The Importance of Stacking

This is where I start to get passionate. I’ve seen too many folks stack their wood in damp, shady corners, only to complain that it won’t dry. The location of your woodpile is just as important as, if not more important than, whether or not you cover it.

Here’s what to look for:

• Sunlight: Choose a location that gets plenty of direct sunlight, especially during the hottest part of the day. South-facing locations are ideal in the Northern Hemisphere.
• Wind: Find a spot that’s exposed to prevailing winds. This will help to wick away moisture from the wood.
• Elevation: Avoid low-lying areas where water tends to accumulate. A slightly elevated location will help to keep the wood dry.
• Clearance from the ground: Never stack firewood directly on the ground. This will trap moisture and promote rot. Use pallets, scrap lumber, or even a layer of gravel to create a barrier.
• Proximity to your house: Consider the convenience of accessing your firewood, especially during inclement weather. However, avoid stacking firewood too close to your house, as this can attract pests like termites and rodents. A good rule of thumb is to keep it at least 20 feet away.

Stacking Techniques:

The way you stack your firewood is crucial for airflow. Here are a few proven methods:

• The traditional row stack: This is the most common method, where you stack rows of wood side by side, leaving small gaps between each row.
• The Holzhaufen (round stack): This method creates a circular stack of wood, which allows for excellent airflow from all directions. It’s more labor-intensive but visually appealing and effective. I’ve found this method particularly useful for smaller quantities of wood.
• The crisscross stack: This involves alternating the direction of the wood in each layer, creating a more stable stack with good airflow.

My Personal Experience:

I once stacked a large pile of oak in a seemingly sunny spot, only to discover that a nearby tree cast a shadow over the pile for most of the afternoon. The wood took significantly longer to dry than expected, and I ended up having to move the entire stack to a more suitable location. Lesson learned: always observe the sun’s path throughout the day before choosing a stacking location.

3. Covering Firewood: The Right Way and the Wrong Way

Okay, let’s get to the heart of the matter: covering firewood. As I mentioned earlier, covering firewood can be beneficial, but only if done correctly.

The Pros of Covering:

• Protection from rain and snow: Covering firewood can prevent it from getting soaked, which can significantly slow down the drying process.
• Reduced leaching of nutrients: Rainwater can leach out valuable nutrients from the wood, making it less efficient as fuel. Covering can help to prevent this.
• Aesthetics: A neatly covered woodpile can be more visually appealing.

The Cons of Covering:

• Trapped moisture: If not done correctly, covering firewood can trap moisture and create a humid environment, which can promote mold and rot.
• Reduced airflow: Covering the entire woodpile can restrict airflow, slowing down the drying process.
• Increased pest activity: A covered woodpile can provide a sheltered environment for pests like insects and rodents.

The Right Way to Cover Firewood:

• Top cover only: The key is to cover only the top of the woodpile, leaving the sides exposed for airflow. This will protect the wood from rain and snow while still allowing it to breathe.
• Use a tarp or metal roofing: A tarp is the most common option, but metal roofing can also be effective. Make sure the cover is large enough to overhang the sides of the woodpile slightly, preventing rainwater from running down the sides.
• Elevate the cover: Use boards or bricks to elevate the cover slightly above the woodpile. This will improve airflow and prevent moisture from getting trapped.
• Secure the cover: Use ropes or bungee cords to secure the cover in place, preventing it from blowing away in the wind.
• Consider a woodshed: If you have the space and resources, a woodshed is the ideal solution for storing firewood. A woodshed provides excellent protection from the elements while still allowing for ample airflow.

My Personal Experience:

I once made the mistake of completely covering a woodpile with a tarp, thinking I was doing it a favor. A few weeks later, I discovered that the wood underneath was damp and moldy. I quickly removed the tarp and allowed the wood to dry out, but it took much longer than it would have if I had just left it uncovered in the first place. This taught me the importance of airflow.

4. Choosing the Right Wood: Species and Splitting

The type of wood you’re drying and how you process it also plays a significant role in the drying process.

Wood Species:

Different wood species have different densities and moisture contents, which affect how quickly they dry.

• Hardwoods: Hardwoods like oak, maple, and ash are denser and take longer to dry than softwoods. However, they also burn hotter and longer.
• Softwoods: Softwoods like pine, fir, and spruce dry more quickly but burn faster and produce more smoke.

Splitting:

Splitting firewood is essential for several reasons:

• Increased surface area: Splitting wood increases the surface area exposed to air, which speeds up the drying process.
• Reduced drying time: Split wood dries much faster than unsplit logs.
• Easier handling: Split wood is easier to handle and stack.
• Better burning: Split wood burns more efficiently than unsplit logs.

When to Split:

Ideally, you should split firewood as soon as possible after felling the tree. This will allow the wood to begin drying immediately. However, some people prefer to wait until the wood has partially dried before splitting it, as it can be easier to split when it’s slightly drier.

Tools for Splitting:

There are several tools you can use to split firewood, including:

• Axes: Axes are the traditional tool for splitting firewood. They are relatively inexpensive and easy to use, but they require a fair amount of physical strength.
• Mauls: Mauls are heavier than axes and are designed for splitting larger pieces of wood.
• Hydraulic log splitters: Hydraulic log splitters are powered by a hydraulic pump and can split even the largest logs with ease. They are more expensive than axes and mauls but can save a lot of time and effort. According to a study by the U.S. Forest Service, using a hydraulic log splitter can increase firewood production by up to 50%.

My Personal Experience:

I’ve used all of the above tools at various points in my firewood journey. I started with an axe and quickly realized that it wasn’t the most efficient way to split large quantities of wood. I then upgraded to a maul, which was a significant improvement. Eventually, I invested in a hydraulic log splitter, and it has been a game-changer. It has saved me countless hours of labor and has allowed me to process much larger quantities of wood.

Optimizing Log Handling Efficiency:

I’ve found that using a log dolly or a skid steer with log forks can significantly improve log handling efficiency, especially when dealing with larger logs. This reduces strain on your body and speeds up the overall process.

5. Monitoring Moisture Levels: The Key to Success

The only way to know for sure if your firewood is dry enough is to measure its moisture content.

Moisture Meters:

Moisture meters are handheld devices that measure the moisture content of wood. They are relatively inexpensive and easy to use. Simply insert the probes of the meter into a freshly split piece of wood, and the meter will display the moisture content as a percentage.

Target Moisture Content:

As I mentioned earlier, the ideal moisture content for firewood is below 20%. However, wood with a moisture content of up to 25% can still be burned effectively.

Testing Methods:

• The “Sizzle Test”: When you burn the wood, listen for a sizzling sound. This indicates that the wood still contains moisture.
• The “Weight Test”: Dry wood is significantly lighter than wet wood. If a piece of wood feels heavy for its size, it probably still contains moisture.
• The “Bark Test”: The bark of dry wood will be loose and easily peel away from the wood.

Data-Backed Insights:

Research from various forestry departments consistently shows that allowing hardwoods to dry for at least 6-12 months is crucial for achieving optimal moisture levels. Softwoods may dry faster, but monitoring is still essential.

My Personal Experience:

I once thought my firewood was dry enough based on its appearance and weight. However, when I burned it, it produced a lot of smoke and didn’t burn very hot. I decided to test the moisture content with a moisture meter, and I was surprised to find that it was still over 30%. I realized that I had underestimated the drying time and that I needed to be more diligent about monitoring moisture levels.

Beyond the Basics: Advanced Tips and Tricks

Now that we’ve covered the fundamentals of drying firewood, let’s dive into some advanced tips and tricks that can help you take your firewood game to the next level.

Sustainable Timber Sourcing

Where your wood comes from matters. Consider sourcing your timber sustainably. This could mean:

• Harvesting from your own property: If you have a wooded property, you can harvest trees for firewood. Just make sure to follow sustainable forestry practices and avoid over-harvesting.
• Purchasing from a local sawmill: Local sawmills often have scrap lumber that they are willing to sell at a discounted price. This is a great way to get high-quality wood for firewood.
• Using reclaimed wood: Reclaimed wood, such as old barn beams or construction lumber, can be a great source of firewood. Just make sure the wood is free of nails and other metal objects.

Material Sourcing Strategies:

I often network with local arborists and tree removal services. They’re often happy to offload wood to me that they would otherwise have to dispose of. This is a win-win situation for both of us.

Workflow Optimization

Efficient workflow is key to maximizing firewood production. Here are a few tips:

• Batch processing: Instead of processing wood one piece at a time, try to process it in batches. This will save you time and effort.
• Ergonomics: Pay attention to ergonomics to avoid injuries. Use proper lifting techniques and take breaks when needed.
• Tool maintenance: Keep your tools sharp and well-maintained. This will make your work easier and safer.

Tool Usage Efficiency: Chainsaw Maintenance Routines:

I’ve found that a regular chainsaw maintenance routine, including sharpening the chain, cleaning the air filter, and checking the bar oil level, significantly improves the chainsaw’s performance and extends its lifespan.

Minimizing Wood Waste

Wood waste is a common problem in firewood production. Here are a few ways to minimize it:

• Use small pieces for kindling: Small pieces of wood that are too small to be used as firewood can be used for kindling.
• Compost sawdust and wood chips: Sawdust and wood chips can be composted and used as a soil amendment.
• Use wood scraps for other projects: Wood scraps can be used for a variety of other projects, such as building birdhouses or planters.

Case Studies: Successful Firewood Projects

Let’s take a look at a few case studies of successful firewood projects to see these strategies in action.
