The Excellent Rain Gardens
Rain gardens are the excellent options for making a difference in water quality in our communities. The rain gardens are gardens that are made in slightly depressed areas in front of a home. It is built near a source of surface runoff, which is its primary source of irrigation. If you are wondering how to build a rain garden, then the first thing that you need to do is select a location for the rain garden. Select a location for the rain garden that receives plenty of sunlight so that the excess water gets evaporated quickly. Make sure that the location of the rain garden is at least 12-15 feet away from the perimeter of the house. This is because if it is too near the house, it will cause water to seep into the foundation which might compromise the integrity of your house’s foundation. An ideal location for a rain garden is a spot that ends at a natural slope. This will make the water from the storm water runoff naturally flow to the area.
You can have a rain garden of any size, but make sure that the size is proportional to the area of the property and that it enhances the landscape. The depth of the rain gardens for a ground which is fairly level should be around 3-5 inches. For ground that has a slight slope to it, a depth of 6-8 inches is sufficient. A natural shape like an oval, kidney or a teardrop shape looks more attractive than a square or rectangular shaped rain garden. So choose a shape that looks natural and gels well with the landscape.
