Rain Garden

What is a Rain Garden?

A rain garden is a garden that is planted in a shallow depression in your yard. This depression is planted with Wisconsin native wetland or prairie wildflowers and grasses.

 

Benefits of a Rain Garden

-Rain gardens increase the amount of water that filters into the ground. This then recharges the local and regional aquifers.     

-They help by protecting communities from flooding and other drainage problems.

-Rain gardens also help protect lakes and rivers from pollutants that would be carried from storm water. Such as lawn fertilizers.

-They enhance the beauty of yards along with neighborhoods.

-They also provide valuable habitat for birds, butterflies and many beneficial insects.

Choosing the Best Location

-Pick a low spot in your yard at least 10 feet from your house.

-Needs to be in front of a downspout or in direct water flow. 

-The spot also needs at least a half day of sun.

-Don't place directly over a septic system.

-The typical size range from 100 to 300 square feet.

Planning and Starting Your Rain Garden

1.) You need to dig a shallow depression that has a level bottom. Dig it the size you want for the garden.

2.) Direct your downspout or sump pump outlet into your rain garden. This can be done by digging a shallow swale or by using buried 4 inch PVC piping.

3.) Plant native Wisconsin plants in a design that suites you.

4.) Water for the first few weeks to help the plants get established.

5.) Once your rain garden is established it requires low maintenance!
