Rain Gardens: A Creative Solution to Your Drainage Problems
One problem with installing a drainage system to keep your yard dry, such as a French drain, is the final destination of the runoff water. Where is it all going to end up? One excellent solution is to create a rain garden. This landscape feature offers a way to eliminate excess water on your lawn and also beautify your property at the same time. Here is a look at some of the considerations involved.
How They Work
A rain garden holds excess water that comes from the drainage system. The plants and soil in the garden keep the water from turning the lawn into a soggy mess. The excess water will seep into the ground over time. Also, the plants in the rain garden can help to remove any pollutants from the water.
Best Locations
The best location for the rain garden is a low spot or depression in your yard. You want to make certain the spot is not too close to your foundation. Pick an area that is at least ten feet away from your house. If you have a septic tank, make certain that the location is well away from the septic system as well. Another key consideration is your water table, which is how high your groundwater rises at a its peak. The seasonal high water table at the location should be no higher than 24 inches from the surface.
Excavating the Garden
It's possible to excavate a small rain garden yourself, if you don't mind getting your hands dirty. Large excavations are probably best left to the experts. You can dig out the area with either a shovel or a rented mini-excavator. Before you do any digging, however, make sure to contact your utility companies so that your do not disturb any underground cables.
Dig out an area about five feet by ten feet. The depth of the bed should be about two feet and the sides of the bed should be slightly sloped.
Finishing the Job
To finish the job, place a mixture of compost and sand into the hole. Leave a space of about six inches below the level of the soil for the water to collect. Place a variety of plants that thrive in wet conditions in the center of the garden and species that tolerate standing water closer to the edges.
Creating a rain garden is one of the most intriguing ways to dispose of any excess water on your property. For more information, contact a drainage contractor.
