I threw in some 2 year old mulberry last night on top of some coals and it took off great and man did it throw off some serious heat! I have about a cord and a half of it left and I will wait colder days. It put on a firework show when reloading but the hearth is big so I was not worried. I will seek out more of this wood for future years! Really pretty yellow when split then it turns sort of a purple color when aged. Anyone else burn it?
