Use alot of mulberry. Has to be bone dry due to it's high resin content. Depending on how you originally buck the wood will depend on seasoning. Spilt rounds with more surface area, you see where i'm going. Minimum of a year for large splits and so forth. It's a heavy wood, so weight will tell you alot. I burn coals so I chunk and use small splits (1"x4") so they dry alot quicker. Usually I keep a 1/2 loaf pan in bottom half of smoker to season them faster. Ends should be checked (spidered) heavy with a considerable weight loss. Try a piece in your chimney or on your gasser, should have a nice cotton candy aroma with no acrid or bitterness. If it crackles and pops heavy, it's not ready. It tends to burn hot so I keep an eye on temps when feeding the beast. Just my observations.
