A classic rain garden layout design typically includes a shallow depression in the ground, designed to capture and absorb stormwater runoff. The garden is planted with native plants that are well-suited to withstand periodic flooding and wet conditions. The design often incorporates a variety of plants, from tall trees and shrubs to ground cover and perennials, to create a diverse and visually appealing landscape. Proper soil preparation, including the addition of organic matter, is crucial to ensure good drainage and water retention. Rain gardens can help reduce runoff, filter pollutants from stormwater, and conserve water by allowing rainfall to infiltrate the ground.
