NOTE:Soil mix used isn't soil less mix (Miracle gro, etc.); isn't potting mix/soil either. All soil found is 40 lbs. per bag.

Topsoil will be used in raised beds, isn't only thing in them; is an 'ingredient' in a soil mix.

What was found yesterday, listed below:

Normal Topsoil; is this just 'black dirt' w/out anything mixed in?

Garden Magic (blend of topsoil, peat, and sand)

Mixes want to use call for peat as separate ingredient.

Should I just use normal topsoil ? Want decent quality topsoil, not something that is blended though. Supposedly packaged topsoil can have soilborne
microbes and/or weed seeds. Is this true?

Soil mixes are below for reference:

Mix one:65% screened top soil, 20% compost, 10% well aged manure, and 5% peat.

Mix two:

"I would suggest a raised bed soil would be about 70-80% mineral components as the structural base - topsoil, sand, fine Turface ... and 20-30% other organic ingredients to make up the rest. It won't matter much what the organic ingredients ARE, because at that low % they won't affect the structure much as it relates to drainage. I think that finished compost or pine bark fines are an excellent addition because neither will significantly immobilize nitrogen (even if it does, that's fixable). Reed/sedge peat is another good choice."
