Rain gardens are a beautiful solution to the problem of water runoff as well as standing water. Planting a rain garden can also help prevent erosion and the pollution of local waterways.
How do they work? A rain garden collects water from impermeable surfaces like roads, driveways, compacted soil and off of your roof. Plants in your garden will absorb most of the water, flourishing and adding beauty. Excess water will drain through the soil to re-enter the water cycle. The soil and plants of your garden will naturally filter out pollutants that might be in the water. In fact, it’s estimated that the average rain garden can filter over 30,000 gallons of water a year!
When building your rain garden, it’s important to keep it a minimum of 10-20 feet away from your home. This keeps the standing water away from the foundations of your house and prevents future damage from forming. Make use of low spots in your yard when designing your rain garden. Water naturally runs into these spots which makes them the perfect place for a rain garden. The ideal soil is sandy and well-draining. If your soil is heavy clay (a common occurrence in Hampton Roads) amend it with compost.
Plants Suitable for Rain Gardens
Native plants are the ideal ones to use when creating a rain garden. Because they are native to your area, they are well equipped to handle the weather (and rain) that commonly occurs. Use a mix of perennials, grasses, and shrubs to create an eye-catching garden with function. Many plants used to create a rain garden are also great for attracting pollinators.
