Notes

WARNING: Old man pine (especially wilding pines like P. contorta) is extremely resinous and produces dangerous amounts of creosote. The aged, dense resin creates thick, glazed creosote deposits that are the leading cause of chimney fires. If you must burn it, mix sparingly with hardwood and sweep your chimney frequently.

Frequently Asked Questions

Is old man pine safe to burn?

Old man pine is one of the most dangerous NZ firewoods due to extreme resin content. It creates thick, glazed creosote deposits (Stage 3) that cause chimney fires. If you must burn it, mix very sparingly with hardwood and sweep your chimney frequently.

What is the difference between old man pine and regular pine?

Old man pine refers to aged or wilding pines (P. nigra, P. contorta) with very dense, resin-saturated wood. It produces far more creosote than young radiata pine and is significantly more dangerous.
