G and 'B Soil Building Conditioner'

G&B Organics Soil Building Conditioner is an OMRI Listed blend formulated to loosen heavy clay soils, improve drainage, and introduce beneficial soil biology. The ingredient list includes recycled forest products, arbor fines, composted chicken manure, gypsum, oyster shell and dolomite limes for pH adjustment, vermicompost, bat guano, kelp meal, and mycorrhizal inoculants. The gypsum and lime combination addresses both drainage and pH, while the mycorrhizae support root establishment in soils that have been compacted or depleted. The pH range of 5.9 to 7.4 suits most Pacific Northwest garden plants.

Work it into native soil before planting, or spread it as a top-dressing mulch around established plants. At 1-inch depth, a 1.5 cubic foot bag covers about 9 square feet. For clay soil improvement, dig it in to at least 6 inches and plan to reapply the following season, as structural changes in clay take time. It works well for flower gardens, in-ground vegetable beds, and any area where drainage is a persistent problem.

Oregon coast soils are often clay-heavy and slow to drain, which makes a product like this one genuinely useful here. The OMRI certification means it is safe for edible gardens, and the absence of synthetic chemicals keeps it compatible with the beneficial insects and soil life that healthy gardens depend on.
