Is Sweetgum Good Firewood? (5 Expert Tips for Best Results)

Sweetgum (Liquidambar styraciflua) is a common hardwood tree found throughout the eastern United States. Known for its star-shaped leaves and spiky seed pods, it’s often considered a nuisance tree, especially in suburban landscapes. But its abundance also means it’s readily available as a potential source of firewood.

The user intent is to determine whether sweetgum is a viable option for firewood and to learn how to best utilize it if so.

Understanding the Basics: What Makes Good Firewood?

Before we dive into the specifics of sweetgum, let’s define what constitutes “good” firewood. Several factors come into play:

• Heat Output (BTU): This measures the amount of heat a wood species produces when burned. Higher BTU ratings generally mean more heat per cord.
• Ease of Splitting: Some woods split easily, while others are notoriously difficult. This impacts the labor involved in preparing firewood.
• Seasoning Time: Green wood contains a high moisture content and needs to be dried (seasoned) before burning. The faster a wood seasons, the sooner it’s ready for use.
• Smoke Production: Some woods produce excessive smoke, which can be a nuisance and pose health risks.
• Coaling Ability: Good coaling woods burn down to hot coals that provide sustained heat.
• Sparking: Some woods, like softwoods, tend to spark and pop, making them less suitable for open fireplaces.

Sweetgum: The Good, the Bad, and the Ugly

Sweetgum’s reputation as firewood is mixed. Here’s a breakdown of its pros and cons:

The Good:

• Availability: Sweetgum is readily available in many areas. In my own experience, I’ve often found landowners eager to have sweetgum trees removed, making it a potentially free or low-cost firewood source.
• Decent Heat Output: While not the highest, sweetgum’s BTU rating is respectable, falling in the middle range of hardwood species. It produces roughly 20 million BTU per cord. (This is a general estimate; actual BTU can vary based on moisture content and tree age.)
• Burns Relatively Cleanly: When properly seasoned, sweetgum burns with less smoke than some other woods.

The Bad:

• Difficult Splitting: This is sweetgum’s biggest drawback. Its interlocking grain makes it incredibly challenging to split, especially when green.
• Slow Seasoning: Sweetgum takes longer to season than many other hardwoods, typically requiring at least 12-18 months of air drying.
• Tendency to Warp: As it dries, sweetgum has a tendency to warp and twist, making it harder to stack neatly.
• Not a Great Coaler: Sweetgum doesn’t produce long-lasting, hot coals like oak or hickory.

The Ugly:

• Smell: Some people find the smell of burning sweetgum unpleasant, describing it as acrid or sour. I personally haven’t found it overwhelmingly offensive, but it’s worth noting.

Expert Tip #1: Embrace the Hydraulic Splitter

Let’s face it: trying to split green sweetgum with a maul is an exercise in frustration. I’ve tried it. I’ve spent hours swinging, grunting, and ultimately giving up in defeat. That’s where a hydraulic log splitter becomes your best friend.

• Why a Hydraulic Splitter? These machines use hydraulic pressure to force a log through a splitting wedge. They provide the necessary force to overcome sweetgum’s stubborn grain.
• Choosing a Splitter: Look for a splitter with at least 20 tons of splitting force. Models with 25-30 tons are even better, especially for larger, knotty sweetgum logs. I personally use a 27-ton splitter, and it handles most sweetgum with ease.
• Safety First: Always wear safety glasses and gloves when operating a log splitter. Keep your hands clear of the splitting area and follow the manufacturer’s instructions carefully.
• Alternative Technique: If you don’t have access to a hydraulic splitter, consider using wedges and a sledgehammer. Drive the wedges into cracks and along the grain to gradually split the wood. This is still labor-intensive, but more effective than trying to split it with a single swing of a maul.

My Experience: I remember one particularly stubborn sweetgum log that I swore was made of iron. Even my 27-ton splitter struggled with it. Eventually, I had to use multiple wedges and work my way around the log, splitting off smaller pieces until I could finally tackle the core. It was a long process, but it proved that even the toughest sweetgum can be conquered with the right tools and persistence.

Expert Tip #2: Split it Green (But Not Too Green)

While it seems counterintuitive, splitting sweetgum while it’s still green can actually make the process slightly easier.

• The Logic: When green, the wood fibers are more pliable and haven’t fully hardened. This allows the splitter or wedges to penetrate more easily.
• The Catch: Wood that is too green is incredibly heavy and saturated with water, making it messy and difficult to handle.
• The Sweet Spot: The ideal time to split sweetgum is a few weeks after felling the tree. The wood will have started to dry slightly, but the fibers will still be relatively flexible.
• Timing Matters: I’ve found that splitting sweetgum in the late fall or early winter, after the leaves have fallen but before the ground freezes, is often the best time. The cooler temperatures help to slow the drying process, giving you a longer window to work with the wood.

Case Study: The Fall Felling Project: A few years ago, I helped a friend clear some sweetgum trees from his property. We felled the trees in late October and waited about three weeks before splitting them. The wood was still heavy, but it split much more easily than the sweetgum logs I had tried to split fresh earlier in the year.

Expert Tip #3: Debark for Faster Drying

Removing the bark from sweetgum logs can significantly speed up the seasoning process.

• Why Debark? Bark is relatively impermeable, meaning it restricts the flow of moisture out of the wood. Removing the bark allows the wood to dry more evenly and quickly.
• How to Debark: There are several ways to debark logs:
  • Hand Tools: A drawknife or spud can be used to peel the bark off manually. This is a labor-intensive process, but effective for smaller logs.
  • Power Tools: An angle grinder with a debarking attachment can make quick work of removing bark, especially on larger logs.
  • Natural Process: If you don’t want to debark the logs yourself, you can simply leave them in a sunny, well-ventilated area. The bark will eventually loosen and fall off naturally, but this will take much longer.
• My Preferred Method: I prefer using an angle grinder with a debarking wheel. It’s faster and less strenuous than hand tools, and it leaves a relatively clean surface.
• Bonus Tip: Debarking also helps to prevent insect infestations, as many wood-boring insects live under the bark.

Statistical Advantage: A study by the Forest Products Laboratory found that debarked logs dry up to 30% faster than logs with bark intact.

Expert Tip #4: Optimize Your Stacking Technique

Proper stacking is crucial for efficient seasoning. Here’s how to stack sweetgum firewood for optimal drying:

• Location, Location, Location: Choose a sunny, well-ventilated location for your woodpile. Avoid areas that are shaded or damp.
• Elevate the Wood: Stack the wood on pallets or sleepers to keep it off the ground. This allows air to circulate underneath the pile, preventing moisture from wicking up from the ground.
• Single Rows: Stack the wood in single rows, with each row separated by a few inches. This allows air to flow freely around each piece of wood.
• Crisscross the Ends: Crisscross the ends of the rows to create a stable structure and further improve airflow.
• Cover the Top: Cover the top of the woodpile with a tarp to protect it from rain and snow. Leave the sides open to allow for ventilation.
• Orientation: Ideally, orient the woodpile so that it runs north-south. This will maximize exposure to sunlight throughout the day.
• Stack Height: Limit the height of the woodpile to no more than 4-5 feet. Taller piles can become unstable and restrict airflow.

My Stacking Method: I use a modified rick rack stacking method. I start by laying down two rows of pallets, spaced about 4 feet apart. Then, I stack the wood in alternating rows, with each row perpendicular to the one below it. This creates a very stable and well-ventilated structure.

Expert Tip #5: Mix it Up!

Sweetgum isn’t the best firewood on its own. It burns relatively quickly and doesn’t produce long-lasting coals. However, it can be a valuable addition to your firewood mix.

• Blending Strategy: Mix sweetgum with denser hardwoods like oak, hickory, or maple. The hardwoods will provide sustained heat, while the sweetgum will help to get the fire started and keep it burning.
• Start with Sweetgum: Use sweetgum to start your fire, as it ignites relatively easily. Once the fire is established, add the denser hardwoods.
• Layering: Layer sweetgum and hardwoods in your firebox. This will help to maintain a consistent burn and prevent the fire from dying down too quickly.
• Experiment: Experiment with different ratios of sweetgum to hardwoods to find what works best for your stove or fireplace.
• Local Considerations: Where I live, oak is plentiful, so I use sweetgum as a kindling and shoulder season wood, saving the oak for the depths of winter.

Strategic Advantage: Mixing firewood not only improves the burning characteristics of your fire but also allows you to utilize a wider range of available resources. This can save you money and reduce your reliance on a single type of wood.

Addressing the Smell Issue

As mentioned earlier, some people find the smell of burning sweetgum unpleasant. Here are a few tips to minimize the odor:

• Proper Seasoning: Well-seasoned sweetgum will produce less smoke and odor than green wood.
• Hot Fires: Burn sweetgum in a hot, efficient fire. This will help to burn off the volatile compounds that cause the odor.
• Chimney Maintenance: Keep your chimney clean and well-maintained. A dirty chimney can contribute to smoky fires and unpleasant odors.
• Ventilation: Ensure adequate ventilation in your home. This will help to dissipate any odors that may be present.
• Air Purifier: Consider using an air purifier with a carbon filter to remove odors from the air.

My Personal Take: I’ve found that the smell of burning sweetgum is most noticeable when the wood is damp or not fully seasoned. Once the wood is properly dried and burned in a hot fire, the odor is minimal.

Safety Considerations

Firewood preparation can be dangerous. Always follow these safety precautions:

• Wear Protective Gear: Wear safety glasses, gloves, and sturdy boots when handling firewood.
• Use the Right Tools: Use the appropriate tools for the job and ensure that they are in good working condition.
• Be Aware of Your Surroundings: Watch out for tripping hazards and other potential dangers.
• Work in a Safe Area: Work in a well-lit and well-ventilated area.
• Take Breaks: Take frequent breaks to avoid fatigue.
• Lift Properly: Lift heavy objects with your legs, not your back.
• Never Work Alone: Always work with a partner, especially when felling trees or operating heavy machinery.
• Fire Safety: Keep a fire extinguisher or water hose nearby when burning firewood.
• Carbon Monoxide Detectors: Install carbon monoxide detectors in your home to protect against carbon monoxide poisoning.

My Safety Rule: I have a strict rule that I never operate a chainsaw or log splitter when I’m tired or distracted. It’s just not worth the risk.

Cost Analysis

The cost of sweetgum firewood will vary depending on your location and the availability of the wood. If you can harvest sweetgum from your own property or obtain it for free from landowners, your costs will be minimal. However, if you have to purchase sweetgum firewood, it will likely be less expensive than premium hardwoods like oak or hickory.

Cost Breakdown (Estimates):

• Free: Harvesting from your own property or obtaining from landowners.
• Low Cost: $50-$100 per cord (if purchased from a local source).
• Moderate Cost: $100-$200 per cord (if purchased from a firewood dealer).

Note: These are just estimates. Actual costs may vary.

Conclusion: Sweetgum – A Firewood to Consider, With Caveats

So, is sweetgum good firewood? The answer, as with many things, is “it depends.” It’s not the best firewood out there, but it’s also not the worst. Its availability and decent heat output make it a viable option, especially if you have access to a hydraulic splitter and are willing to put in the extra effort to season it properly.

The Bottom Line:

• If you’re looking for the absolute best firewood, stick with denser hardwoods like oak or hickory.
• If you’re on a budget and have access to sweetgum, it can be a worthwhile option, especially if you mix it with other hardwoods.
• If you’re physically fit and enjoy a challenging workout, you can try splitting sweetgum by hand, but be prepared for a battle.
• If you value convenience above all else, sweetgum may not be the best choice for you.

Ultimately, the decision of whether or not to use sweetgum as firewood is a personal one. Consider your individual needs, resources, and preferences. And remember, with the right tools and techniques, even the most challenging wood can be transformed into a source of warmth and comfort.
