Burning Ficus Wood in Fireplaces: What You Need to Know

Ron asked whether wood from a large ficus tree, once dried, would burn well in a fireplace, having heard it might be "rubbery" and burn poorly. The short answer: yes, properly seasoned ficus wood can be burned, but with some caveats.

Understanding Ficus Wood Properties

Ficus species (including common fig trees and ornamental ficus) produce wood that is indeed less dense than traditional firewood favorites like oak, hickory, or maple. The "rubbery" description likely refers to the wood's higher moisture content when green and its somewhat fibrous texture. However, once properly seasoned—dried to 20% moisture content or less—most woods become serviceable firewood.

Seasoning Is Critical

• Drying Time: Ficus wood should be split and stacked for at least 6-12 months in a well-ventilated, covered area.
• Moisture Testing: Use a moisture meter to confirm it's below 20% before burning.
• Storage: Keep seasoned wood off the ground and covered on top but open on sides for airflow.

Burning Characteristics

Even when well-seasoned, ficus wood will:

• Burn faster than dense hardwoods
• Produce less heat per log (lower BTU output)
• Create a decent bed of coals once established
• Work best mixed with denser woods for sustained heat

Practical Tips

Start your fire with a good bed of hot coals from denser wood, then add ficus logs. This approach compensates for ficus's lower initial heat output. Never burn unseasoned (green) wood of any species—it wastes energy evaporating moisture, creates excessive smoke, and deposits dangerous creosote in your chimney.

While ficus won't match oak's heating performance, it's perfectly acceptable as supplementary firewood, especially if you have the tree coming down anyway. The key is proper seasoning and realistic expectations.
