Firewood in Cape Town: Which Wood Burns Best, and Which Wood Must Not Be Moved

Neatly stacked split hardwood firewood seasoning under cover — Split and stacked off the ground under cover — six to twelve months to season.

Rooikrans is the best braai wood in the Western Cape, and it is also a NEMBA Category 1b invasive that landowners are required to control — so clearing it and burning it are the same job. It is dense, low in resin, and burns down to a long, even coal bed instead of flaring and dying. Pine does the opposite. One rule overrides all of this: wood from a tree infested with shot hole borer must never leave the property.

How Cape woods actually burn

Wood	Coal bed	Verdict
Rooikrans (Acacia cyclops)	Long, even, hot	The Cape standard. Dense, low resin, minimal spitting.
Black wattle (Acacia mearnsii)	Good	Solid second choice. Denser than Port Jackson, below rooikrans.
Kameeldoring / hardwoods	Very long	Excellent but usually trucked in from far off, and priced accordingly.
Port Jackson (Acacia saligna)	Short, light	Kindling and rough burning. Fast, and gone.
Blue gum / eucalyptus	Moderate	Burns hot once seasoned. Green gum spits and tars a chimney.
Pine	Poor	Resinous, fast, sparks. Fine for starting a fire, poor for cooking on.

The rules that matter

Why must infested wood stay on site?

The polyphagous shot hole borer lives inside the wood, and firewood is how it travels long distances in a single step. Moving infested logs to another property, selling them, or putting them into a green-waste stream is how an outbreak jumps suburbs. Suspect material is chipped fine on site or disposed of as the authorities direct.

How long does Cape firewood need to season?

Six to twelve months split and stacked off the ground under cover, depending on the species and the summer. Green wood wastes most of its energy boiling off its own water, which is why it hisses, smokes and never produces a decent coal bed.

What should never go on a braai?

Treated timber, painted or varnished wood, old pallets and anything with preservative in it. CCA-treated pine releases arsenic compounds when burned. None of it belongs anywhere near food.

Clearing rooikrans or wattle produces usable firewood, and on most jobs the default is to chip everything — say so beforehand if you want the timber cut and stacked instead, because once it is through the chipper the option is gone. Alien invasive clearing
