Rain garden soil is a soil blend designed to support plant growth while promoting rapid infiltration and filtration of stormwater. It typically consists of a mix of sand, compost, and topsoil, carefully proportioned to allow water to drain efficiently while still retaining enough nutrients and moisture for healthy plant development.The ideal rain garden soil has high permeability and good structure, enabling it to absorb water quickly and release it slowly into the surrounding ground. This makes it an essential component in sustainable landscaping and stormwater management.This soil plays a critical role in the function of a rain garden by:Filtering pollutants from stormwater runoffSupporting deep-rooted native plants that enhance infiltrationPreventing compaction and promoting healthy microbial activityReducing erosion and helping manage heavy rainfall eventsRelated Products: Premium Black Mulch or a layer of Decorative Pebbles may assist the plant establishment process without compromising the garden function.
