The only thing we have around here to burn is oak and hickory. I love hickory but it really needs two years to season well if it's cut green. It will burn after one year but so much better after two, just like oak. I also recommend that you split it right away. I had a dozen or eight inch rounds that I left unsplit for a couple of years. Neither an 8lb maul or my Fiskars SS will make a dent in them.
They've been sitting out for almost three years now. I started using them whole for overnight burns.
