Why Our Professional Potting and Bedding Soil Performs

Balanced Structure

This professional potting and bedding soil provides proper pore space for oxygenation, consistent moisture distribution, reduced compaction over time, and excellent root establishment.

Composted rice hulls support drainage, add silica, and improve soil structure. They’re renewable, biodegradable, and continue improving soil quality over time—helping support stronger and healthier plants.

Optimized Water Management

Mix #15 professional potting and bedding soil is designed to retain adequate moisture while draining efficiently, reducing the risk of root rot and supporting uniform crop performance.

Our blend of rich milled redwood and clay helps store moisture, while rice hulls give roots the breathing room they need—delivering superior moisture retention compared to perlite-based alternatives.

Nutrient Support

Mix #15 supplies a well-rounded nutrient base suitable for a wide variety of plants. The addition of dolomite helps maintain an ideal pH range and supports consistent fertilization programs for strong early-stage root development.

It acts as a slow-release soil conditioner that improves soil structure, reduces nutrient deficiencies, and enhances microbial activity. Lime also provides calcium, supporting nutrient availability and extending the productive life of growing media.

Proper soil aeration and organic structure are essential for healthy plant growth. Research from the USDA Soil Health Initiative explains how soil structure supports stronger root systems and plant resilience.
