Blended Soils

Blended soils are made by combining recycled organic material with sand, soil or other products to form a growing medium. Blended soils may supply nutrients, increase moisture and nutrient holding capacity and can help drainage.

Screened Topsoil

Screened Topsoil is a non-amended sandy loam topsoil free of roots, clods, and stones larger than 3/8” with 99% passing through a 3/8” screen.

A-1 Planter Mix

A-1 Planter Mix is a blend of washed sand, organic fines, A-1 Lifelike™ 3/8” Compost, peat moss and aqua gro (a wetting agent to enhance the mixtures ability to absorb water). This soil is relatively lightweight due to its high organic content and extremely low clay content.  Although it has a superior percolation rate, its water and nutrient holding ability greatly reduces leaching of valuable plant nutrients and minerals.

A-1 Bioretention Soil Mix

A-1 Bioretention Soil Mix is a blend of 80% washed coarse sand and 20% sandy loam topsoil. The blended material is low in silt and clay which allows the material to perform at the required minimum drainage properties of ˃ 5” per hour KSat Perc Rate @ 85% relative compaction. This satisfies civil engineering requirements while maintaining the agronomical properties of a well graded sand with silt to satisfy the landscape architect’s desire to support growth of plant material. Clay content is limited to provide a minimum cation exchange capacity for healthy plant material if desired.
