Splitting Difficulty: Some eucalyptus species can be stringy and challenging to split, especially when green.
Resin Content: The high resin content can lead to popping and spitting, so it’s best to burn eucalyptus in a closed stove or fireplace.

Takeaway: Eucalyptus offers a unique combination of benefits and drawbacks. Understanding these factors will help you decide if it’s the right firewood choice for you. My personal experience has been overwhelmingly positive, but I always take precautions to mitigate the potential issues.

The Art of Coppicing: A Sustainable Harvest

Coppicing is an ancient woodland management technique that involves cutting trees down to near ground level, stimulating them to produce numerous new shoots from the stump. These shoots, known as “coppice stools,” grow rapidly and can be harvested after a specific period, typically ranging from a few years to several decades, depending on the species and desired product.

Why Coppicing Works So Well with Eucalyptus:

Vigorous Regrowth: Eucalyptus is exceptionally well-suited to coppicing. It’s in its nature to regenerate from the base.
Sustainable Yield: Coppicing allows you to harvest wood repeatedly from the same tree without replanting, promoting long-term sustainability. I’ve been coppicing the same stand of eucalyptus for over a decade.
Improved Tree Health: Regular coppicing can actually improve the health and vigor of the trees.
Habitat Creation: Coppiced woodlands create a diverse habitat for wildlife, providing food and shelter for various species.

Coppicing Techniques: A Step-by-Step Guide:

Timing is Key: The best time to coppice eucalyptus is during the dormant season, typically in late winter or early spring before new growth begins. I usually aim for February or March in my region.
Choose the Right Trees: Select trees that are of suitable size and maturity for coppicing. I generally look for trees that are at least 4-5 years old.
Make Clean Cuts: Use a sharp chainsaw or axe to make clean, angled cuts as close to the ground as possible. Angled cuts help prevent water from pooling on the stump, reducing the risk of rot.
Remove Debris: Clear away any debris from around the base of the coppiced tree to allow for unobstructed growth of the new shoots.
Monitor Growth: Keep an eye on the coppice stools and thin out any weak or overcrowded shoots to promote healthy growth of the remaining stems. I typically thin them after the first growing season.

Takeaway: Coppicing is a sustainable and efficient way to manage eucalyptus for firewood production. By following these simple techniques, you can ensure a continuous supply of wood for years to come. I find it incredibly rewarding to see the trees regenerate and provide me with fuel year after year.

The density of the wood directly correlates to its heat output and burn time. Choosing the right species can make a significant difference in your firewood experience.

Top Eucalyptus Species for Firewood:

Eucalyptus globulus (Blue Gum): One of the densest eucalyptus species, known for its high heat output and long burn time. I consider this the gold standard for eucalyptus firewood.
Eucalyptus camaldulensis (River Red Gum): Another excellent choice, with a good balance of density and availability. It’s also relatively easy to split compared to some other species.
Eucalyptus sideroxylon (Red Ironbark): Extremely dense and hard, providing exceptional heat and long-lasting coals. However, it can be very difficult to split.
Eucalyptus cladocalyx (Sugar Gum): A good all-around choice, with decent density and relatively easy splitting.

Understanding Wood Density:

Wood density is measured in pounds per cubic foot (lbs/ft³). The higher the density, the more energy the wood contains. For example:

Eucalyptus globulus: Approximately 60 lbs/ft³
Eucalyptus camaldulensis: Approximately 55 lbs/ft³
Pinus radiata (Radiata Pine): Approximately 30 lbs/ft³

As you can see, eucalyptus is significantly denser than many softwood species, resulting in a higher heat output. I always check the density rating of a species before committing to using it as firewood.

Identifying Eucalyptus Species:

Identifying eucalyptus species can be challenging, but there are a few key characteristics to look for:

Bark: Eucalyptus bark comes in a variety of colors and textures, from smooth and shedding to rough and fibrous.
Leaves: The shape and size of the leaves can also help identify different species.
Flowers: Eucalyptus flowers are distinctive, with numerous stamens that give them a fluffy appearance.

Takeaway: Choosing the right eucalyptus species is crucial for maximizing heat output and burn time. Research the density and characteristics of different species in your area to make an informed decision. I always recommend starting with Eucalyptus globulus or Eucalyptus camaldulensis if they are available.

Expert Tip #3: Seasoning for Optimal Burn

Seasoning, or drying, firewood is crucial for achieving optimal burn. Green wood contains a high moisture content, which reduces its heat output, increases creosote production, and makes it difficult to ignite.

Why Seasoning Matters:

Increased Heat Output: Dry wood burns hotter and more efficiently than green wood.
Reduced Creosote: Seasoned wood produces less creosote, reducing the risk of chimney fires.
Easier Ignition: Dry wood ignites more easily and burns more consistently.
Less Smoke: Seasoned wood produces less smoke, making it more environmentally friendly.

The Seasoning Process:

Split the Wood: Splitting the wood exposes more surface area, allowing it to dry more quickly.
Stack the Wood: Stack the wood in a single row, off the ground, in a sunny and windy location. This promotes air circulation and accelerates the drying process. I use pallets to keep the wood off the ground.
Cover the Top: Cover the top of the woodpile with a tarp or other waterproof material to protect it from rain and snow. Leave the sides open to allow for ventilation.
Monitor Moisture Content: Use a moisture meter to monitor the moisture content of the wood. Firewood is considered seasoned when it reaches a moisture content of 20% or less.

Seasoning Time for Eucalyptus:

Eucalyptus typically requires a longer seasoning time than many other hardwoods due to its density. I recommend seasoning eucalyptus for at least 9-12 months, and longer in humid climates.

Signs of Properly Seasoned Wood:

Cracks: Seasoned wood will develop cracks on the ends of the logs.
Weight: Seasoned wood will be significantly lighter than green wood.
Sound: When struck together, seasoned wood will produce a hollow sound.
Moisture Meter Reading: A moisture meter will indicate a moisture content of 20% or less.

Takeaway: Seasoning is an essential step in preparing eucalyptus firewood. By following these guidelines, you can ensure that your wood burns efficiently, cleanly, and safely. I always make sure to have a year’s supply of seasoned wood on hand.
