A rain garden is a beautiful and eco-friendly landscaping feature that helps manage stormwater runoff effectively. It is designed to capture and absorb rainwater from roofs, driveways, and other surfaces, allowing it to slowly infiltrate into the ground rather than flowing into storm drains and causing pollution.

- Size and Shape: Determine the size and shape of the rain garden based on the amount of runoff it needs to manage.
- Soil Preparation: Ensure the soil in the rain garden is well-draining and amend it with compost if needed.
- Plant Selection: Choose a variety of native plants that can tolerate both wet and dry conditions.
- Maintenance: Regular maintenance, such as weeding and mulching, is essential to keep the rain garden functioning properly.
How to Build a Rain Garden
Building a rain garden requires some basic construction skills and the right materials. Here is a general overview of the steps involved in constructing a rain garden:
- Mark the Area: Outline the shape and size of the rain garden using spray paint or a garden hose.
- Excavation: Dig a shallow basin in the marked area, ensuring proper slope for water flow.
- Install Inlet and Outlet: Connect the rain garden to the downspout from your roof to direct water into the garden.
- Amend Soil: Add compost or sand to improve the soil’s drainage capacity.
- Planting: Arrange the selected plants in the rain garden, leaving space for growth and proper spacing.
