Native Rain Gardens

These are pictures of building a rain garden at the Museum of Transportation a St. Louis County Park.

All this excessive amount of water comes off a very large parking lot. A smaller rain garden can be built in your yard from the water coming from your gutters or neighbors yard. Just scale down this concept.

Just choose a low, already wet spot in your yard. Dig out six to nine inches of the area. Add two inches of compost and mix it in. This will improve the drainage of the area. So now you have a shallow bowl like area that will hold approximately six inches of water. The water should be absorbed into the water table in less than forty eight hours. If it doesn’t you should add more compost or make it shallower. Rocks and boulders can be used to control erosion and to beautify the area.

Look at my list of native plants and choose the rain garden plants for the wettest area. The other natives or perennials can be planted in the surrounding areas.
