how much space does half a cubic metre of mulch cover
Member of forum. 1 cubic meter of mulch will cover 10 square meters at 100mm deep, a 6x4 trailer is approx 0.76 cublic meters, so at 100mm deep u will need 0.5 cubic meters, at 50mm ull need 0.25 cubic meters, always order a little extra though.Independent and i know it.
