Our Organic Soil Conditioner Mix is a nutrient-rich amendment crafted from a premium blend of rice hulls, sawdust, iron sulfate, poultry manure, and gypsum. Designed to break up heavy clay soils common in Napa and Solano, this mix improves drainage, boosts aeration, and enhances long-term soil health.
Locally sourced and blended, it’s ideal for gardeners, landscapers, and vineyard managers looking to enrich planting beds, vegetable gardens, lawns, or orchard soils. The balanced combination of organic matter and minerals helps restore depleted soils, encouraging strong root development and healthier plant growth.
Whether you’re revitalizing compacted soil in Vallejo, preparing raised beds in Benicia, or supporting vineyard soils in Napa Valley, this conditioner delivers reliable results season after season.

Yes. Our mix of rice hulls, sawdust, poultry manure, gypsum, and iron sulfate is safe and beneficial for vegetable gardens, raised beds, and home orchards. It naturally improves soil fertility and plant health.
Q: How much soil conditioner do I need for my project?
One cubic yard covers about 100 sq. ft. at a 3-inch depth. For vineyards, we recommend applying in rows at a lighter depth; for gardens or lawns, a thicker layer works best when tilled into native soil.

You can plant immediately after mixing into the soil. For best results, till or rake the conditioner thoroughly before planting.
