I burn both mulberry and hedge (Osage Orange). I personally burn way more mulberry because everyone goes so nuts for the hedge around here for fenceposts and firewood, mulberry is often overlooked. Hedge puts out more heat, but Andy is right, it throws way more sparks and pops more than MOST mulberry, although I have burned mulberry that throws sparks bad occaisonally. I have never burned any mulberry that stank, could be a different species here in Kansas? Also, I cure ALL my wood one year whether its Oak, Hackberry, Ash, Locust, Mulberry...etc, and it always burns wonderful for me.
