Can You Use Christmas Tree as Firewood? (5 Drying Tips)
Let’s embark on an exploration of whether that festive Christmas tree can find a second life warming your home.
Can You Use Christmas Tree as Firewood? (5 Drying Tips)
The scent of pine, the crackling fire – it’s a scene many of us cherish. But what happens when the holidays are over, and that once-proud Christmas tree is standing forlornly by the curb? The question inevitably arises: Can you use a Christmas tree as firewood? The short answer is yes, you can, but with significant caveats.
I have spent decades in the woods, from felling timber on my family’s land to advising small-scale logging operations. I have seen firsthand the consequences of burning improperly seasoned wood. It’s more than just a smoky fire; it can be a real safety hazard. So, let’s dive into the nuances of turning your Christmas tree into usable firewood.
The Allure and the Reality
There’s a certain appeal to the idea. Repurposing something that would otherwise end up in a landfill feels good. Plus, the thought of that familiar pine fragrance filling your home again is enticing. However, the reality is that Christmas trees, typically fir, spruce, or pine, are softwoods with high resin content. This means they burn hot and fast, producing a lot of smoke and creosote.
Creosote is a nasty byproduct of incomplete combustion that sticks to your chimney walls. It’s highly flammable and a leading cause of chimney fires. According to the Chimney Safety Institute of America (CSIA), chimney fires cause over $126 million in property damage annually. So, while the idea is appealing, safety must be your top priority.
Wood Anatomy and Properties: Understanding Softwoods
To understand why Christmas trees behave differently as firewood, let’s delve into wood anatomy. Softwoods, like those used as Christmas trees, have a less dense cellular structure compared to hardwoods such as oak or maple. This lower density means they dry faster but also burn quicker.
- Cell Structure: Softwoods have simpler cell structures, primarily composed of tracheids (water-conducting cells). Hardwoods have more complex structures with vessels and fibers, contributing to their density and burning characteristics.
- Resin Content: Coniferous trees, like fir and pine, are known for their resin canals. Resin is a flammable organic compound. When burned, it creates a characteristic aroma, but also contributes to smoke and creosote production.
- Moisture Content: Freshly cut Christmas trees have a very high moisture content, often exceeding 50%. This moisture needs to be significantly reduced before the wood can be burned safely and efficiently.
- BTU Output: Softwoods generally have a lower BTU (British Thermal Unit) output per cord compared to hardwoods. BTU measures the amount of heat released upon burning. For example, a cord of seasoned oak might produce 24 million BTUs, while a cord of seasoned pine might produce only 15 million BTUs.
Logging Tool Selection and Maintenance Best Practices: Preparing the Tree
Before you even think about burning your Christmas tree, you need to process it. This involves cutting it into manageable pieces and splitting the larger sections. Here’s where having the right tools and knowing how to maintain them is crucial.
- Chainsaw: A chainsaw is essential for cutting the tree into smaller rounds. Choose a chainsaw appropriate for the task. A small to medium-sized saw with a 14-16 inch bar is usually sufficient for processing Christmas trees. Ensure the chain is sharp. A dull chain not only makes the job harder but also increases the risk of kickback. I always recommend wearing proper safety gear, including eye protection, hearing protection, and chainsaw chaps.
- Splitting Axe or Maul: For splitting the rounds, you can use a splitting axe or a maul. An axe is lighter and better for smaller rounds, while a maul is heavier and more effective for larger, tougher pieces. Consider a hydraulic log splitter if you have a large volume of wood to process regularly. Hydraulic splitters significantly reduce the physical strain involved in splitting wood.
- Hand Tools: A hatchet or small splitting wedge can be useful for smaller pieces or for starting splits in larger rounds.
- Tool Maintenance: Regularly clean and sharpen your tools. A sharp axe or chainsaw is safer and more efficient. For chainsaws, check the chain tension and oil level before each use. For axes and mauls, inspect the handle for cracks and ensure the head is securely attached. I always keep a file handy to touch up the chain on my saw after every tank of gas. It makes a world of difference.
Firewood Seasoning Techniques and Safety Considerations: The Drying Game
The key to safely burning a Christmas tree is proper seasoning. Seasoning is the process of drying wood to reduce its moisture content. Freshly cut wood can have a moisture content of 50% or higher. For efficient and safe burning, you want to get that down to 20% or less.
- The Stack: Stack the wood off the ground to allow for air circulation. Use pallets or scrap wood to create a base. Stack the wood loosely in rows, leaving gaps between the pieces. This promotes airflow and speeds up the drying process. I like to stack my wood in a single row, oriented east to west, to maximize sun exposure.
- The Cover: Cover the top of the stack to protect it from rain and snow. A tarp works well, but make sure to leave the sides open for ventilation. You don’t want to trap moisture in the stack.
- The Location: Choose a sunny and windy location for your woodpile. Sunlight and wind are your best allies in the drying process. Avoid stacking wood in damp or shaded areas.
- The Time: Seasoning takes time. Softwoods like pine dry faster than hardwoods, but you should still aim for at least 6-12 months of seasoning. The exact time will depend on your climate and the type of wood.
- The Test: How do you know when the wood is dry enough? There are a few ways to tell. Dry wood will be lighter in weight than green wood. It will also have cracks or splits on the ends. You can also bang two pieces of wood together. Dry wood will produce a hollow sound, while green wood will sound dull. A moisture meter is the most accurate way to measure moisture content. Aim for a reading of 20% or less. I use a moisture meter regularly, especially when I’m burning wood I haven’t seasoned myself.
- Safety First: Always wear gloves and eye protection when handling firewood. Be aware of insects and spiders that may be living in the woodpile. Never burn unseasoned wood in an enclosed space. It will produce excessive smoke and creosote, posing a fire hazard.
Project Planning and Execution: From Tree to Fire
Let’s break down the process of turning your Christmas tree into firewood step by step.
- Acquire the Tree: Once the holidays are over, remove all decorations from your tree. This includes tinsel, ornaments, and lights.
- Cut into Rounds: Using a chainsaw, cut the tree into rounds. The size of the rounds will depend on the size of your fireplace or wood stove. I usually cut mine into 12-16 inch lengths.
- Split the Rounds: Split the larger rounds into smaller pieces. This will help them dry faster and burn more efficiently.
- Stack the Wood: Stack the wood in a sunny and windy location, off the ground, and covered on top.
- Season the Wood: Allow the wood to season for at least 6-12 months.
- Test the Moisture Content: Before burning, test the moisture content of the wood. Use a moisture meter to ensure it is 20% or less.
- Burn Safely: Burn the seasoned wood in a fireplace or wood stove that is properly maintained and inspected.
