Rain gardens are designed to capture, hold, and absorb stormwater runoff from roofs, driveways, patios, and compacted lawns. During light to moderate rainfall, a properly built rain garden collects water and allows it to soak into the soil within 24–48 hours. However, during heavy storms or prolonged rain, even a well-designed rain garden can overflow…

Driveways create significant runoff because they are usually made of concrete, asphalt, or pavers—materials that do not absorb water. During heavy rain, water flows quickly off the surface, often carrying: A rain garden placed downhill or adjacent to the driveway captures this runoff before it enters storm drains, acting as a natural filtration system. Key…

A rain garden berm is a small but essential feature that makes the entire system work. While plants, soil, and basin shape get most of the attention, the berm is what allows the rain garden to hold water long enough for it to soak into the ground. Without a properly built berm, water will simply…

Designing a rain garden starts with one crucial question: how big should it be? If the garden is too small, it won’t capture enough runoff and may overflow. If it’s too large, you’ll spend unnecessary time, effort, and money excavating and planting more than needed. The good news is that rain garden sizing is based…

The success of your rain garden starts with proper placement. Choose a spot that: The goal is to intercept water before it flows into storm drains. Step 2: Test the Soil Drainage (Percolation Test) Before digging, check how well your soil drains. If water drains within 24 hours, the site is suitable. If it remains…

Excavating a rain garden is one of the most important steps in creating a functional, long-lasting stormwater solution in your yard. While planting and design get most of the attention, proper excavation is what determines whether your rain garden will effectively absorb runoff or turn into a soggy pit. Done correctly, excavation shapes the basin,…

Before any materials go into the ground, you need tools to shape the rain garden basin. Tools required: These tools help you excavate the shallow basin that will hold and absorb rainwater. 2. Marking Materials for Layout To plan the shape and size of your rain garden, you’ll need simple marking items: These help you…

Rain gardens are often pictured as lush, gently sloped landscape features in large yards or public parks. But the truth is far more encouraging for homeowners and urban dwellers: rain gardens can absolutely be installed in small spaces. Whether you have a compact backyard, a narrow side yard, a townhouse patio edge, or even a…
