We call poplar, "gopher wood." As in, "Oh, dang, I need to go for wood again already." As you say, though, just fine for early and late season when you don't need the best heat. No sense in wasting it!I have a cord of poplar from a tree that broke over in late winter in 3 racks. Not the best burning wood but good for early or late season.
Pine burns fast. How big is the log?Pine wood is what we have.
Try to get some hardwoods (ash, oak, maple, fruit woods, nut woods) if you can. They burn longer and cleaner. Ash is about the best, I've heard.
We have a LOT of oak, and I love the smell of freshly cut or split oak wood. It splits easily and well, too.
