Seasoning starts after the wood is Cut, Split & Stacked (CSS) off the ground.
Neatly or at least stacked in row with 12" or so of space between rows to have wood season.
Some wood is good to go (dry enough) in a year, some in 2 years & the red oaks in 3 year CSS.
Allot depends on your weather, wood type & air circulation.
I believe top cover only helps keep the rain off but still gets lots of air circulation.
"Time" is what wood need to season. Precious commodity for fire wood too
2 to 3 years ahead is a goal for me.
Burning dry wood: burn less wood, get more heat, no or very little creosote, burns cleaner .
Large mounds of wood will rot in the center & bottom of the pile way before it dries well enough to burn.
If not Cut & Split & reasonably stacked, it won't season much if at all.
Wood don't season in the log form. (very little in rounds ) Drier than a live tree but not dry enough to burn.
