Can one use coal ash in garden?
Or thrown away.
Does it have to be stored in the dry under a tarp, like wood.
Coal ash is good for gardens in low doses or mixed with other amendments (softrock phosphates, greensand, lava sand, etc) You could also mix it into compost pile.
There is a weekly gardening thread here on FR.

Not sure.
“Does it have to be stored in the dry under a tarp, like wood.”
I get mine in bags.
Depends on the coal. Some can have mercury, arsenic and various heavy metals in the deposit.
I would not put it in a food garden unless you are sure of the composition
Once you have a nice bed of coals burning wet coal dries very quickly and ignites easily. It doesn’t absorb moisture anywhere near what wood does. Just have to be careful storing wet coal inside because its been known that it can spontaneously combust.
U don’t have to store it in the dry...it has been around for millions of years, so water or snow ain’t gonna worry it.
I burnt some the other day covered in snow....hissed for a while, then burnt right up.
A coal fire on a winters night...nothing better.
There’s a chance of toxic metals in it so you probably want to avoid using it on food plants.
