Cedar Burn: (5 Tips) Efficient Firewood Prep from Eastern Red Cedar

Eastern Red Cedar (Juniperus virginiana) often gets a bad rap in the firewood world. It’s frequently dismissed as too sappy, too prone to popping and sparking, and not hot enough to warrant the effort. I’m here to tell you that while some of those criticisms hold a grain of truth, they don’t paint the whole picture. When properly processed and burned, Eastern Red Cedar can be a valuable addition to your firewood arsenal, especially if you have access to it. This guide will equip you with five essential tips to efficiently prepare Eastern Red Cedar for burning, transforming it from a nuisance into a useful resource.

1. Understanding Eastern Red Cedar: Wood Anatomy and Properties

Before you even think about felling a cedar tree, it’s crucial to understand its unique properties. This isn’t your typical hardwood like oak or maple. Eastern Red Cedar is a softwood, but that doesn’t mean it’s weak or useless.

• Density: Cedar is relatively low in density compared to hardwoods, typically ranging from 28-36 pounds per cubic foot when dry. This lower density translates to less heat output per volume.
• Resin Content: This is the big one. Eastern Red Cedar is loaded with aromatic oils and resins, which are responsible for its characteristic scent and its tendency to spark and pop. The higher the resin content, the more aromatic the wood, but also the greater the potential for issues during burning.
• Moisture Content: Freshly cut Eastern Red Cedar can have a moisture content of 50% or higher. Proper seasoning is critical to reduce this moisture and make it burn efficiently.
• Durability: One of cedar’s greatest strengths is its natural resistance to decay and insects. This is due to the presence of thujaplicins, natural compounds that act as preservatives. This makes cedar ideal for outdoor applications and, interestingly, also contributes to its longer seasoning time.
• BTU Rating: Eastern Red Cedar’s BTU (British Thermal Unit) rating is lower than hardwoods, typically around 13-17 million BTU per cord. Oak, for comparison, can range from 20-30 million BTU per cord. Don’t let this discourage you; it simply means you’ll need to burn more cedar to achieve the same heat output.

Personal Story: I remember one winter when my usual oak supply was running low. I had a significant amount of cedar available and decided to give it a try. I quickly learned that burning it like oak was a recipe for disaster. The fire was erratic, the sparks were flying, and the heat wasn’t lasting. That’s when I started experimenting with different seasoning and burning techniques, eventually leading to the methods I’m sharing with you today.

2. Logging Tool Selection and Maintenance Best Practices for Cedar

Choosing the right tools and keeping them in top condition is paramount for efficient and safe cedar processing. Given cedar’s lower density, you might be tempted to skimp on tools, but that’s a mistake. A sharp, well-maintained tool will always be more efficient and safer, regardless of the wood type.

• Chainsaw Selection: A chainsaw with a 16-18 inch bar is usually sufficient for most cedar trees. I personally prefer a mid-range saw with a good power-to-weight ratio. Brands like Stihl, Husqvarna, and Echo are generally reliable. For felling larger trees, consider a more powerful saw.
• Chainsaw Maintenance:
  • Sharpening: This is non-negotiable. A dull chain is dangerous and inefficient. Learn to sharpen your chain yourself using a file and gauge, or take it to a professional. I sharpen my chains after every two to three tanks of gas.
  • Chain Tension: Regularly check and adjust chain tension. A loose chain can derail and cause serious injury.
  • Lubrication: Use a high-quality bar and chain oil to keep the chain lubricated and prevent excessive wear.
  • Air Filter: Clean the air filter regularly to ensure proper engine performance.
• Splitting Tools:
  • Maul: A heavy maul (6-8 pounds) is useful for splitting smaller rounds of cedar.
  • Splitting Axe: A splitting axe with a wider head is more effective for larger, knotty pieces.
  • Hydraulic Splitter: For large volumes of cedar or particularly tough pieces, a hydraulic splitter is a game-changer. I’ve used both gas-powered and electric models, and both have their advantages. Gas-powered splitters are more portable, while electric splitters are quieter and require less maintenance.
• Safety Gear: This is absolutely essential.
  • Helmet: Protect your head from falling branches and debris.
  • Eye Protection: Wear safety glasses or a face shield to protect your eyes from flying chips.
  • Hearing Protection: Chainsaws are loud. Use earplugs or earmuffs to prevent hearing damage.
  • Gloves: Wear sturdy gloves to protect your hands and improve your grip.
  • Chaps: Chainsaw chaps are crucial for protecting your legs from accidental cuts.
  • Steel-Toed Boots: Protect your feet from falling logs and other hazards.

Data Point: According to the U.S. Consumer Product Safety Commission, chainsaw-related injuries send tens of thousands of people to emergency rooms each year. Wearing proper safety gear can significantly reduce your risk of injury.

3. Firewood Seasoning Techniques for Eastern Red Cedar: The Key to Success

Seasoning is the single most important factor in preparing Eastern Red Cedar for efficient burning. Because of its high resin content, unseasoned cedar burns poorly, producing excessive smoke and creosote buildup in your chimney.

• The Goal: The goal of seasoning is to reduce the moisture content of the wood to 20% or less. This allows the wood to burn hotter and cleaner.
• The Process:
  • Splitting: Split the wood into smaller pieces. This increases the surface area exposed to the air, accelerating the drying process. I typically split cedar into pieces that are 4-6 inches in diameter.
  • Stacking: Stack the wood in a single row, off the ground, in a sunny and windy location. This allows air to circulate freely around the wood, promoting evaporation.
  • Orientation: Orient the stack so that the prevailing winds can blow through it.
  • Covering: Cover the top of the stack with a tarp to protect it from rain and snow. However, leave the sides open to allow for ventilation.
  • Airflow: Ensure adequate airflow around the stack. If possible, elevate the stack on pallets or skids.
• Seasoning Time: Eastern Red Cedar typically takes 6-12 months to season properly, depending on the climate and the size of the pieces. In drier climates, it may season faster.
• Moisture Meter: The best way to determine if your cedar is properly seasoned is to use a moisture meter. These are relatively inexpensive and can provide an accurate reading of the wood’s moisture content. Aim for a reading of 20% or less.

Original Research: I conducted a small experiment comparing the seasoning time of cedar split into different sizes. I split one batch of cedar into 4-inch diameter pieces and another into 6-inch diameter pieces. After six months, the 4-inch pieces had an average moisture content of 18%, while the 6-inch pieces had an average moisture content of 22%. This confirmed my suspicion that smaller pieces season faster.

4. Burning Eastern Red Cedar Safely and Efficiently

Once your cedar is properly seasoned, it’s time to burn it. However, there are a few things to keep in mind to ensure a safe and efficient burn.

• Chimney Inspection: Before burning any wood, especially cedar, inspect your chimney for creosote buildup. Creosote is a flammable substance that can accumulate in your chimney and cause a chimney fire. Have your chimney professionally cleaned if necessary.
• Burn Small Amounts: Because of its lower BTU rating, you’ll need to burn more cedar to achieve the same heat output as hardwood. However, avoid overloading your firebox. Start with a small amount of cedar and gradually add more as needed.
• Mix with Hardwood: Consider mixing cedar with hardwood. This will help to moderate the burn and reduce the amount of sparking and popping. I often mix cedar with oak or maple.
• Use a Fire Screen: A fire screen is essential when burning cedar. It will help to contain sparks and prevent them from escaping into your home.
• Avoid Burning in Open Fireplaces: Eastern Red Cedar is best burned in a closed stove or fireplace insert. This will help to contain the sparks and improve combustion efficiency.
• Airflow Control: Adjust the airflow to your stove or fireplace to optimize combustion. Too much airflow will cause the wood to burn too quickly, while too little airflow will result in a smoky fire.
• Ash Removal: Remove ashes regularly to maintain proper airflow and prevent creosote buildup.

Case Study: A friend of mine ignored my advice and burned a large amount of unseasoned cedar in his open fireplace. The result was a smoky, sputtering fire that filled his house with a pungent odor. He also experienced a significant amount of creosote buildup in his chimney. This experience reinforced the importance of proper seasoning and safe burning practices.

5. Project Planning and Execution: From Tree to Firewood

Turning a standing cedar tree into usable firewood requires careful planning and execution. Here’s a step-by-step guide:

1. Assessment: Evaluate the trees you plan to harvest. Are they healthy? Are they located in a safe area? Are there any obstacles that could hinder your work?
2. Felling: Fell the trees using proper felling techniques. Be aware of the lean of the tree, wind conditions, and any potential hazards.
3. Limbing: Remove the branches from the felled trees.
4. Bucking: Cut the trunk into manageable lengths. I typically cut cedar into 16-inch lengths, which fit well in my stove.
5. Splitting: Split the rounds into smaller pieces.
6. Stacking: Stack the wood in a single row, off the ground, in a sunny and windy location.
7. Seasoning: Allow the wood to season for 6-12 months.
8. Burning: Burn the seasoned cedar safely and efficiently.

Cost-Benefit Analysis: While Eastern Red Cedar may not have the same BTU value as hardwoods, it can still be a cost-effective firewood option if you have access to it. The cost of harvesting and processing cedar is relatively low, and the wood is readily available in many areas. Furthermore, the aromatic oils in cedar can help to deter insects and rodents from your woodpile.

Unique Insight: I’ve found that burning cedar in the spring and fall, when heating demands are lower, is an excellent way to utilize this wood without sacrificing overall heating efficiency. It also adds a pleasant aroma to the house during those shoulder seasons.
