The Good, the Bad, and the Elm: A Deep Dive

Elm is a common tree throughout North America and Europe, so chances are, you’ll encounter it at some point. The key is knowing what to do with it.

Wood Anatomy and Properties: Unlocking Elm’s Secrets

To truly understand elm, we need to peek under the bark and examine its cellular structure. Elm belongs to the Ulmaceae family, and the two most common species you’ll encounter are American elm (Ulmus americana) and slippery elm (Ulmus rubra).

• Grain and Texture: Elm has an interlocked grain, which is what makes it so darn tough to split. Think of it like a woven basket – the fibers run in multiple directions, resisting separation. This interlocked grain also contributes to its high bending strength, which is why elm was historically used for things like wagon wheel hubs.
• Density: Elm is a medium-density hardwood, typically ranging from 35 to 45 pounds per cubic foot when dry. This puts it in the same ballpark as ash and soft maple.
• Moisture Content: Freshly cut elm can have a moisture content of well over 60%. However, it’s susceptible to decay and insect infestation if left unseasoned and exposed to the elements.
• Smell: Elm has a distinct, slightly sour smell when freshly cut. Some people find it unpleasant, while others don’t mind it. The smell fades as the wood seasons.

Logging Tool Selection and Maintenance Best Practices for Elm

Working with elm requires the right tools and a healthy dose of patience. Because of that interlocked grain, you’ll want to have a maul and wedges available. Here’s a breakdown of what I’ve found most effective:

• Chainsaw: A good-quality chainsaw with a sharp chain is essential for felling and bucking elm. I prefer a saw with a bar length of at least 20 inches, as elm logs can be quite large. Keep your chain sharp! Dull chains are a recipe for frustration and potential kickback.
  • Personal Story: I once tried to fell a large elm with a dull chain. After what felt like an eternity, the saw finally bound up, and I had to wrestle it free. Lesson learned: sharp chains are non-negotiable.
• Maul: A heavy-duty maul is your best friend when splitting elm. I recommend a maul with a weight of at least 6 pounds, preferably 8. The extra weight helps to overcome the resistance of the interlocked grain.
• Wedges: Splitting wedges are crucial for dealing with stubborn elm rounds. I keep a variety of wedges on hand, including:
  • Steel wedges: These are the workhorses of the wedge world. They’re durable and effective for most splitting tasks.
  • Fiberglass wedges: These are lighter than steel wedges and less likely to spark, which is a plus when working in dry conditions.
  • Wood Grenades: For particularly gnarly rounds, a wood grenade can be a lifesaver. These are designed to create multiple splitting points, making it easier to break the wood apart.
• Hydraulic Splitter: If you’re processing a lot of elm, a hydraulic splitter is a worthwhile investment. It will save you a tremendous amount of time and effort. I use a 25-ton splitter, which handles even the most challenging elm rounds with ease.
  • Data Point: A hydraulic splitter can increase your splitting efficiency by as much as 500% compared to manual splitting, according to a study by the University of Maine.
• Personal Protective Equipment (PPE): Safety is paramount when working with any kind of wood, but especially with elm. Always wear:
  • Safety glasses: To protect your eyes from flying debris.
  • Hearing protection: Chainsaws are loud, and prolonged exposure to noise can damage your hearing.
  • Gloves: To protect your hands from splinters and blisters.
  • Steel-toed boots: To protect your feet from dropped logs and tools.
  • Chainsaw chaps: To protect your legs in case of a chainsaw mishap.

Maintenance Tips:

• Sharpen your chainsaw chain regularly. A sharp chain cuts faster and more safely.
• Keep your maul and wedges sharp. A dull maul or wedge is less effective and more likely to glance off the wood.
• Inspect your tools regularly for damage. Replace any damaged tools immediately.
• Store your tools in a dry place. This will help to prevent rust and corrosion.
• Follow the manufacturer’s instructions for maintenance and repair.

Firewood Seasoning Techniques and Safety Considerations

Seasoning is the process of drying firewood to reduce its moisture content. Properly seasoned firewood burns hotter, cleaner, and more efficiently. Elm, with its high moisture content, requires a longer seasoning period than many other hardwoods.

• The Goal: The ideal moisture content for firewood is below 20%. At this level, the wood will burn readily and produce minimal smoke.
• The Process:
  1. Split the wood: Splitting the wood exposes more surface area, which speeds up the drying process.
  2. Stack the wood: Stack the wood in a single row, with the bark side up. This allows for maximum air circulation.
  3. Elevate the wood: Elevate the wood off the ground using pallets or cinder blocks. This prevents moisture from wicking up from the ground.
  4. Cover the wood: Cover the top of the woodpile with a tarp or sheet of plywood. This will protect the wood from rain and snow.
  5. Wait: Elm typically takes 12-24 months to season properly.
     • Data Point: A study by the University of Wisconsin found that elm firewood seasoned for 18 months had a moisture content of 18%, while elm firewood seasoned for only 6 months had a moisture content of 35%.
• Testing for Seasoning: There are several ways to test if your firewood is properly seasoned:
  • Visual Inspection: Seasoned firewood will be lighter in color and have cracks on the ends.
  • Sound Test: When you bang two seasoned pieces of firewood together, they will make a hollow sound.
  • Moisture Meter: A moisture meter is the most accurate way to measure the moisture content of firewood. You can purchase a moisture meter at most hardware stores.

Safety Considerations:

• Stacking: Stack firewood on a stable surface to prevent it from collapsing.
• Location: Stack firewood away from your house and other structures to prevent the spread of fire.
• Pests: Be aware that firewood can attract pests, such as insects and rodents. Store firewood away from your house to minimize the risk of infestation.
• Ventilation: When burning firewood indoors, make sure your fireplace or wood stove is properly ventilated. Carbon monoxide poisoning is a serious risk when burning firewood in an enclosed space.
• Ash Disposal: Dispose of ashes in a metal container with a lid. Allow the ashes to cool completely before disposing of them. Never dispose of ashes in a plastic container or near combustible materials.

Project Planning and Execution: Conquering the Elm Mountain

Before you even think about felling an elm tree, it’s crucial to have a solid plan in place. Here’s my tried-and-true approach:

1. Assessment: Carefully assess the tree. Is it healthy? Is it structurally sound? Are there any hazards, such as power lines or buildings nearby? If you’re not comfortable felling the tree yourself, hire a professional arborist.
2. Permits: Check with your local authorities to see if you need a permit to fell the tree.
3. Equipment: Gather all the necessary equipment, including a chainsaw, maul, wedges, PPE, and a first-aid kit.
4. Felling Plan: Develop a detailed felling plan. Determine the direction of fall, and clear any obstacles in the path of the tree.
5. Bucking Plan: Once the tree is on the ground, develop a bucking plan. Decide how you’re going to cut the tree into manageable lengths.
6. Splitting Plan: Determine how you’re going to split the wood. Will you use a maul and wedges, or a hydraulic splitter?
7. Stacking Plan: Decide where you’re going to stack the firewood. Make sure the location is well-drained and has good air circulation.
8. Execution: Follow your plan carefully. Work safely and methodically.
9. Clean Up: Once you’re finished, clean up the area. Remove any debris and dispose of it properly.

Now, let’s get to the crux of the matter: the pros and cons.

5 Pros of Using Elm for Firewood

1. High Heat Output: Elm is a dense hardwood, which means it packs a lot of energy. When properly seasoned, it burns hot and long, providing excellent heat for your home.
   • Data Point: Elm has a BTU (British Thermal Unit) rating of approximately 20 million BTUs per cord, which is comparable to ash and oak.
2. Long Burn Time: Because of its density, elm burns slowly, providing a consistent heat output for an extended period. This means you won’t have to reload your fireplace or wood stove as often.
3. Readily Available: Elm trees are common in many parts of the world, so you’re likely to have access to a supply of elm firewood. This can make it a more affordable option than some of the rarer hardwoods.
4. Acceptable Smoke: While not as clean-burning as some hardwoods, elm produces a reasonable amount of smoke when properly seasoned. This is important for minimizing air pollution and reducing the risk of chimney fires.
5. Good Coaling Qualities: Elm leaves a good bed of coals, which helps to maintain a consistent fire and makes it easier to restart the fire after it burns down.

5 Cons of Using Elm for Firewood

1. Difficult to Split: This is the big one. The interlocked grain of elm makes it notoriously difficult to split, especially when it’s green. This can be a major deterrent for those who prefer to split their firewood by hand.
