Putting in a raised garden which is 38 cubic feet of space. Wasn't sure of the dirt to compost ratio or if it's a good mix. This is what I bought and I can exchange if needed.
"Pro Top Soil" cheap topsoil (says it has some compost in it) 7.5 cubic feet
"Miracle Grow" garden soil. 12 cubic feet
"ECO" organic compost. 6 cubic feet
"Super Soil" enriched planting compost. 4 cubic feet
mushroom compost. 3 cubic feet
sheep & peat mix 3 cubic feet
"Miracle Grow" potting mix 1 1/4 cubic feet
I was reading about mixes and using different products. Does this sound like a good mix. should I add sand or more potting mix or vermiculite?
