Agreed, wood ashes are your best non-skid solution for icy steps and walks.
We spread the ashes over the veggie plot last winter. Come spring I spread some 10-10-10, tilled again and planted. The plants shot up fast this year. I ain't never had summer squash plants this big.
The squash are growing near as fast as I can pick 'em. Gotta get to cooking this weekend. Cukes are fattening up quick. Maters got a late start but they're growing quickly. Cantaloupe vines are all over the place.
Have yer soil tested early before adding wood ash or any amendment for that matter.
