I have 3 huge planter boxes that i need to fill up with dirt/soil so i can plant some shrubs and bushes. I went to golden acre last night and picked up 13 -46 litre bags of soil at $12 a bag and thought that would be enough for all 3 boxes but just 1 took all 13 bags. Id rather not go and spend another $300 on soil if i dont have to so im wondering if i can just use loam and mix it because theres lots of that by me
