15cm of mulch will certainly work well but I think for most of us it would be a luxury. An allotment neighbour near us took on a weeded plot in late November, covered with cardboard and due to budget restrictions topped with about 5cm of compost. She's had a few weeds but nowhere near as many as conventionally worked plots. It would be fair to say that so far it's working really well for her.
I think I'd be inclined to meter your muck out in piles dotted about and see how it looked once spread.
