Janesville sits along the Rock River at 837 feet of elevation, where glacial activity shaped the silt loam soils that define Rock County's landscape character. Those soils hold moisture well but compact under foot traffic and heavy rain, making quality mulch a critical ally for anyone maintaining beds near the river corridor or in the historic neighborhoods surrounding the Lincoln-Tallman House. The growing window in Zone 5b is tight, with the last spring frost arriving around April 28 and the first fall frost closing things down by early October. Customers across Beloit, Edgerton, and Delavan face the same soil and seasonal pressures, and bulk delivery of mulch, topsoil, and decorative stone helps everyone make the most of every week in that window.
