Collection:

All Soil, Media & Amendments

291 products

All Soil, Media & Amendments is built around growing a healthy root zone, with potting soils, soilless media like coco and rooting cubes, dry amendments and minerals, compost, worm castings, and beneficial microbe inoculants that support living soil.

The selection includes FoxFarm's Ocean Forest and Happy Frog lines, Roots Organics and Royal Gold potting mixes, BAS soil recipes, River View Living Soils blends, and Real Growers Recharge microbial inoculant. It works for container gardeners mixing their own soil and for growers who want a bagged, ready-to-plant mix, with everything stocked at GrowTime Garden Supply in Jefferson City, Missouri.
