Started burning my poplar about 10 days ago and I will say this, I will never put it in the racks again as long as better wood is available. Even with it seasoning quick, I will take oak over it. I started burning the poplar about 10 days ago. It has not really been cold over those 10 days and I have almost gone through an entire 24" wide tree of the stuff. About the only thing it has been good for is to get the furnace hot fast. Otherwise, it burns way too quick. Been stuffing the furnace with it at night, which is the only time I am burning right now, and I am lucky if I find a couple hot coals in the furnace in the morning. Good thing it really doesn't matter too much right now. Took the poplar in 2011 when I was just starting my wood piles. Beggars cannot be choosers I guess. Now, it is a different story.
