As said above stack it with weight on top. Blocks,tractor weight, metal. This will prevent warping. I have 1/2 inch x 1 inch strips between this walnut and off the ground. The wood will need to dry several months before using. Using as siding I think it can be nailed up green but still will shrink and warp some. Don’t let metal touch it the acid in the wood will gets stained from the metal it will not come out. You may of seen barns where around the nails are dark. You can also ratchet trap around them together with wood spacing them apart.
