Gardener's soil is a type of soil that is used for gardening and landscaping. It is composed of a combination of LOAM and loess, two types of soil. LOAM is a type of soil that is made up of clay, silt, and sand particles, and is known for its ability to retain moisture and nutrients. Loess is a type of soil that is composed of fine-grained sedimentary material, and is known for its ability to hold water and provide good drainage. Together, these two types of soil make up the ideal soil for gardening and landscaping.
