We use ash all the time in the garden, mixed in with the compost. Usually let the mixture set with other soils etc thru the winter to get the pH balanced out. I've got several experimental areas going where ash is spread/mixed in.Anyone use the ashes you generate in your fireplace/wood burner in the garden? I just tossed my 3rd 50# of ashes in the trash. Maybe I should be spreading them?
Along with the garden, I have (2) 5-gallon buckets (with lids) filled with ash that stay in our vehicles for when vehicles get stuck when icy conditions are present. Haven't found anything that works better.
