OMRI Clarification - Gardner and Bloome
Been looking for an organic potting soil and was recommended G&B Organic Potting Soil and Blue Ribbon Potting Soil by local hardware store.
I looked them up on OMRI and saw all Gardner and Bloome products are listed as Iron Products and saw this caveat:
May be used as a plant or soil amendment only with a documented iron deficiency.
I'm very new to vegetable gardening and was unsure what ingredient would cause that listing:
All organic ingredients of fir bark, forest humus, peat moss, perlite, chicken manure, worm castings, bat guano, kelp meal, alfalfa meal, with oyster shell and dolomite lime for pH adjusters.
Blue Ribbon Mix:
A composted blend of Canadian sphagnum peat moss, screened fir bark fines, forest humus, pumice, chicken manure, worm castings, bat guano, kelp meal & alfalfa meal.
I've seen a few threads on here with others that have successfully used their products and are happy with them but I want to know exactly what's going into my mix.
