I'm burning a lot of Red and Silver Maple this year. I love burning it when I'm at home because it doesn't leave the large amount of coals like my hardwoods do. It's all been seasoned for a year. My Hickory gets those bugs in it that makes a fine dust. Just about every piece of Maple is full of that dust behind the bark. What a mess. Because of the bugs, a lot of the bark is loose so some of it can be pulled off before bringing it in the house, but then some can't be. What a mess. This makes a bigger mess than ashes ever could.
