Okay, this is all good information, and I appreciate it. Now, I have an OT, but similar question.
In the past, I have used most any wood available, for firewood. Typically, it was Walnut, Maple, Eucalyptus, Avocado, some type of citrus, or some form of conifer. I simply burned whatever was available. That was in suburban Lost Angeles. I had a couple of avocado trees on my lot, had a walnut that was taken out, from my lot, years before, and a neighbor, at one time, gave me a half cord of maple, from a tree that he had, on his lot, that died.
All that said, it is clear that I am a novice, at the use of wood, for primary heating.
On my property, I have 3 sizable elm trees, that have fallen, and would be normally used for burning. But, the locals here, tell me that the common name for it is (excuse the vulgarity) "Piss Elm", supposedly, due to its "aroma" when burning. But, in looking it up, on the web, I have found several folks who say it is good wood for firewood. Someone tell me the truth, please. I have already cut up one of them, figuring to burn it, with all of the twigs in the burn pile, after cutting up the red oak, and a couple of large branches of the hackberry. It is set to burn in the middle of the pasture, where it's "aroma" is unimportant. But, if it is good fireplace wood, after all, I can easily place it in the seasoning wood stack.
Help, please?
