Hi folks, my question is, has anyone ever used Chinese Sumac as a firewood. I realize everything burns, however before I go through all the trouble of cutting, splitting and drying I would like to know how well it burns. I have approx. 14 of these large worthless trees that need to come down, all they do is spread seed. Hate to see them just rot in the woods. Nothing eats the new seedlings/saplings and I don't blame the animals the plant/tree just stinks and must taste horrible....John DESCRIPTION Tree-of-heaven, also known as ailanthus, Chinese sumac, and stinking shumac, is a rapidly growing, deciduous tree in the mostly tropical quassia family (Simaroubaceae). Mature trees can reach 80 feet or more in height. HABITAT IN THE UNITED STATES Tree-of-heaven is a common tree in disturbed urban areas, where it sprouts up just about anywhere, including alleys, sidewalks, parking lots, and streets. The book âA Tree Grows in Brooklyn,â by Betty Smith based on the ailanthus tree.
