Rain Gardens

What is all of this buzz about rain gardens?

Rain gardens have the potential to solve stormwater runoff problems before they occur. And, rain gardens add a low maintenance, landscaped feature in your yard!

Typical rain garden installation requires:

  1. A suitable area located between the rainwater source and its destination that is at least 10 feet from a home or building and is either a depressed area or an area where water flows naturally.
  2. Materials, such as:
    1. an appropriate soil-mix (50-60% sand, 20-30% top soil, and 20-30% compost), check your native soil first and have it tested at your local Extension office;
    2. native plants (a hardy mix of grasses, small shrubs, and self-seeding perennials are good choices, especially those that are both wet- and drought tolerant);
    3. a dense-material mulch that won’t float away.
  3. Earth-moving tools (to excavate about 6-9" of soil) and planting tools.
  4. A desire and willingness to manage stormwater on-site and protect water quality.
