Can You Burn Tree of Heaven? (5 Arborist Tips for Best Firewood)

The scent of woodsmoke always takes me back to my grandfather’s farm. He was a master of the axe and the woodstove, and winters there were always warm, not just from the fire, but from the love he poured into splitting and stacking the wood that fed it. He taught me more than just how to swing an axe; he instilled in me a respect for the forest and the hard work that turns trees into fuel. Now, years later, I still carry those lessons with me, and I’m here to share some of that knowledge with you.

Can You Burn Tree of Heaven? (5 Arborist Tips for Best Firewood)

Yes, you can burn Tree of Heaven. However, just because you can doesn’t always mean you should. It’s crucial to understand the properties of this wood and the potential challenges it presents before tossing it into your fireplace or wood stove. Tree of Heaven is considered a low-quality firewood, but in certain circumstances, it can be a viable option, especially when managed carefully.

Why the Hesitation? Understanding Tree of Heaven Firewood

Tree of Heaven isn’t exactly prized for its firewood qualities. Here’s why:

• Low Heat Output: Tree of Heaven is a softwood with a relatively low density. This translates to a lower BTU (British Thermal Unit) rating compared to hardwoods like oak or maple. Expect significantly less heat per cord. Think of it like this: Oak is the heavyweight champion of firewood, while Tree of Heaven is more like a lightweight contender.
• Fast Burning: Because of its low density, Tree of Heaven burns quickly. You’ll find yourself constantly feeding the fire, which can be a nuisance and lead to higher wood consumption.
• Unpleasant Odor (Sometimes): Some people report that burning Tree of Heaven produces an unpleasant odor, particularly when it’s not properly seasoned. The smell is often described as musty or even slightly offensive. I’ve personally experienced this, and it’s not something you want permeating your home.
• Sparks and Popping: Tree of Heaven can be prone to sparking and popping, increasing the risk of stray embers escaping the fireplace. This requires extra vigilance and a good fire screen.
• Invasive Species Concerns: Burning Tree of Heaven, especially if it’s not properly dried, could theoretically contribute to the spread of the invasive species. However, the risk is very low as the seeds are unlikely to survive the combustion process. Still, it’s a point to consider.

The Arborist’s Perspective: When Tree of Heaven Makes Sense

Despite its drawbacks, there are situations where burning Tree of Heaven is a reasonable choice.

• Abundant Availability: If you have a large quantity of Tree of Heaven on your property, and it’s being removed anyway, burning it can be a way to utilize a resource that would otherwise go to waste. I once cleared a patch of overgrown land, and Tree of Heaven was the dominant species. Burning it was a practical solution for disposal.
• Mixing with Hardwoods: Tree of Heaven can be mixed with hardwoods to help get a fire started or to provide a quick burst of heat. Think of it as a kindling substitute.
• Emergency Fuel: In a survival situation or during a power outage, Tree of Heaven can provide a source of heat, even if it’s not ideal.
• Cost-Effectiveness: If Tree of Heaven is free or significantly cheaper than other firewood options, it might be worth considering, especially if you don’t rely solely on wood for heating.

5 Arborist Tips for Burning Tree of Heaven the Right Way

If you decide to burn Tree of Heaven, follow these five tips to minimize the downsides and maximize its potential:

1. Seasoning is Key: This is the most critical step. Tree of Heaven needs to be thoroughly seasoned (dried) before burning. Aim for a moisture content below 20%. Freshly cut Tree of Heaven can have a moisture content of 50% or higher. Proper seasoning dramatically reduces smoke, improves heat output, and minimizes unpleasant odors.

   • How to Season Tree of Heaven:
     • Split the Wood: Split the logs as soon as possible after felling. Smaller pieces dry faster.
     • Stack it Right: Stack the wood in a single row, off the ground, in a sunny, well-ventilated location. Proper airflow is essential. I recommend using pallets or scrap wood to create a base for the stack.
     • Cover the Top: Protect the top of the stack from rain and snow with a tarp or roofing material, but leave the sides open for ventilation.
     • Patience is a Virtue: Allow the wood to season for at least 6-12 months, preferably longer. Use a moisture meter to check the moisture content before burning. You can find these at most hardware stores.
   • Data Point: A study by the University of Tennessee Extension found that properly seasoned firewood burns 50% more efficiently than green wood.

2. Mix it Up: Don’t rely solely on Tree of Heaven for your heating needs. Mix it with hardwoods like oak, maple, or hickory. This will provide a more consistent and higher heat output. I often mix Tree of Heaven with oak that I’ve harvested responsibly from my own property. The oak provides the long-lasting heat, while the Tree of Heaven helps to get the fire going quickly.

   • Mixing Ratios: Experiment with different mixing ratios to find what works best for you. A good starting point is a 50/50 mix of Tree of Heaven and hardwood.
   • Strategic Loading: Load the hardwoods first to establish a good coal bed, then add the Tree of Heaven on top for a quick burst of heat.

3. Burn it Hot: Maintain a hot, clean-burning fire. This helps to reduce smoke and minimize the risk of creosote buildup in your chimney. Creosote is a flammable substance that can cause chimney fires.

   • Airflow is Your Friend: Ensure adequate airflow to the fire. Adjust the air vents on your fireplace or wood stove as needed.
   • Regular Chimney Inspections: Have your chimney inspected and cleaned regularly by a qualified professional. The National Fire Protection Association (NFPA) recommends annual chimney inspections.
   • Expert Quote: “Creosote buildup is a leading cause of chimney fires,” says Ashley Eldridge, Director of Education at the Chimney Safety Institute of America (CSIA). “Regular inspections and cleaning are essential for safe wood burning.”

4. Be Mindful of Sparks: Tree of Heaven can be prone to sparking and popping. Use a sturdy fire screen to prevent stray embers from escaping the fireplace.

   • Screen Quality Matters: Invest in a high-quality fire screen that is made of durable material and has a fine mesh.
   • Keep Combustibles Clear: Keep flammable materials, such as rugs, curtains, and furniture, away from the fireplace.
   • Never Leave a Fire Unattended: Never leave a fire unattended, especially when burning Tree of Heaven.

5. Consider Alternative Uses: Before burning, explore other potential uses for Tree of Heaven.

   • Composting: Tree of Heaven can be composted, providing valuable nutrients for your garden.
   • Mulch: Chipped Tree of Heaven can be used as mulch around trees and shrubs.
   • Craft Projects: The wood can be used for small craft projects, although it’s not particularly strong or durable.
   • Biochar: Consider turning Tree of Heaven into biochar, a charcoal-like substance that can improve soil health and sequester carbon.
   • Case Study: A local community garden near me has started using Tree of Heaven, chipped and composted, as a soil amendment. They’ve reported improved soil structure and increased crop yields. This demonstrates that even an invasive species can be repurposed for beneficial uses.

Optimizing Your Firewood Workflow for Efficiency

Regardless of the type of wood you’re burning, optimizing your firewood workflow can save you time, energy, and money. Here are some tips based on my own experience:

• Planning is Paramount: Before you even start cutting, develop a detailed plan that includes:

  • Ergonomics Matter: Pay attention to your posture and body mechanics to avoid injuries.

  • Lift with Your Legs: When lifting logs, bend your knees and keep your back straight.
  • Take Breaks: Don’t try to do too much at once. Take frequent breaks to rest and stretch.
  • Use Mechanical Assistance: Consider using a log splitter or a log lifter to reduce the strain on your back.

  • Optimize Log Handling: Streamline the process of moving logs from the forest to your woodpile.

  • Use a Log Arch: A log arch can make it easier to move large logs over rough terrain.

  • Skid Logs with a Tractor: If you have access to a tractor, you can use it to skid logs to a central location.
  • Wheelbarrow or Cart: Use a wheelbarrow or cart to transport smaller logs and split wood.

  • Stacking for Success: Proper stacking is essential for efficient drying.

  • Elevate the Stack: Stack the wood on pallets or scrap wood to keep it off the ground.
  • Single Rows: Stack the wood in single rows to maximize airflow.
  • Leave Space Between Rows: Leave a few inches of space between rows to allow for air circulation.
  • Cover the Top: Cover the top of the stack with a tarp or roofing material to protect it from rain and snow.

  • Track Your Progress: Keep track of how much wood you’ve harvested, split, and stacked. This will help you to estimate your firewood supply and plan for future needs.

  • Cord Calculator: Use a cord calculator to estimate the volume of your woodpile.

  • Inventory Management: Keep a record of how much wood you burn each year.

One of my most memorable experiences with firewood involved a particularly harsh winter. A blizzard had knocked out power to our entire region, and we were relying solely on our wood stove for heat and cooking. The only problem was, our wood supply was running low. I had to venture out into the snow-covered forest to harvest more wood. It was a grueling task, but the warmth of the fire and the knowledge that I was providing for my family made it all worthwhile. That experience taught me the importance of preparedness and the value of having a reliable source of fuel. It also reinforced my respect for the power of nature and the resilience of the human spirit.

Another time, I was helping a friend clear some land for a new garden. We came across a large pile of Tree of Heaven that had been cut down and left to rot. Instead of letting it go to waste, we decided to experiment with turning it into biochar. We built a simple kiln out of an old metal drum and carefully controlled the burning process. The resulting biochar was surprisingly effective at improving the soil quality in the garden. It was a great example of how even an invasive species can be repurposed for beneficial uses.

Cost Savings from Optimized Workflows

Optimizing your firewood workflow can lead to significant cost savings. By using efficient tools and techniques, you can reduce the amount of time and energy required to prepare firewood, saving you money on fuel, labor, and equipment maintenance. For example, investing in a hydraulic log splitter can significantly reduce the amount of time spent splitting wood by hand, especially if you’re dealing with a lot of large or knotty logs. A well-maintained chainsaw will cut more efficiently and last longer, saving you money on repairs and replacements. Proper stacking and seasoning will reduce wood waste and improve the efficiency of your fires, saving you money on fuel.
