A Rain Garden is a small, shallow depression in your yard that is planted with native wetland or wet prairie wildflowers and grasses. They are designed to collect water that runs off from your roof or is discharged from your sump pump and allow it to soak into the ground. They can also help filter out pollutants in runoff. Rain Gardens are gaining in popularity because they are low-maintenance and attract birds and butterflies while reducing and treating stormwater runoff.
City of St. Charles Grass and Flower Seed Mix
Did you know the City of Saint Charles Department of Public Works provides free packets of rain garden flower seeds to City residents? These seeds should to be planted in a low-lying area, which tends to stay damp throughout the growing season. The species in this mix will tolerate periodic flooding, as well as dry periods between rainstorms. Once established, these flowers are an excellent way for City residents to improve stormwater quality with native vegetation. This mix is not recommended for dry, sandy soils that drain rapidly and do not retain moisture. This mix is not meant to be planted in flower pots.
Pick up your Rain Garden seeds at City Hall or the Public Works Facility while supplies last. Please limit one (1) packet per resident.
Remove all existing growth, scatter seed evenly and compress into the soil. Do not cover. Fertilizers, and/or lime are unnecessary, as wildflowers are adaptable. Keep area moist until seedlings are 6-8" high; after flowers have been established, they require minimal care. Plant seeds in spring months (March – May) after the danger of frost.
