‘Rain garden’ is a type of ‘planted despair’, which allows rainwater surplus from impermeable urban areas, such as roofs, driveways, pavements, and compressed lawns the opportunity to be engrossed.  Rain garden reduces rain surplus by letting storm water to seep into the ground. Rain garden helps to cut down the amount of pollution by 40 percent, which reaches brooks and streams.

Native plants are considered as a good option for the rain gardens, because, usually they do not require manure and they are tolerant to confined climate, soil, and water conditions.  The plants, a collection of marshland rim flora, such as wild plants, sedges, rushes, ferns, bushes and small trees, seep up surplus water flowing into the rain garden.

Water filters through layers of soil before flowing into the groundwater system. Root systems of plants improve the infiltration, wetness relocation, and diverse microbial populations which are occupied in Bio-filteration.  Due to the ‘transpiration’ process, the plants of the rain garden release water vapor into the atmosphere. In this tutorial you will learn how to create a rain garden and save rain water.

Things require:

1. Shovel
2. Native Plants
3. Drain Pipe
4. Ornamental Garden Accessories of Choice

Instructions:

• First of all select a Location for the rain garden. Everyone has some space in their yard, which gathers water after heavy rain or becomes a mud-hole after a rainstorm. If this location is situated around 12 feet from the house, then it is the ideal location for the rain garden.

• If possible, select the area for the rain garden plan, which will get wholesome sunlight. There must be a natural hill or slope, at least 2% grade, heading from the water compilation area, such as, the roof or driveways, downward to the rain garden.

• Now, examine the soil for your rain garden. Before installation of the rain garden, it is essential to check the soil. Make a 7-inch hole and pour water in it. If the water is still present in the hole, even after 24 hours, then the soil is not permeable enough.

• Find the depth for setting up the rain garden. Eliminate the existing grassland and make a low depression, about 7-inches deep.

• Now slope the sides slowly from the outside rim to the deepest region.
• Use the soil that you got, to make a little raised area on the three down slope sides of the garden. This Berm will help to hold the water overflow and permit it to seep gradually in throughout the rain garden.

• Make a direction for the Rain Water. Deflect the rain water from the crown or other collection region by directing the rain water in the direction of the rain garden. This process can be done either by a natural incline, or by making a shallow channel, or by piping the excess water straight to the garden through a covered 5″ diameter drain pipe.

• Now, select Rain Garden Plants. ‘Native plants’ endure difficult growing circumstances and need very little preservation. These plants are the ideal options for rain gardens.

• Select groups of four to eight native plants; make sure to consider height, blossom time and color. Bunch the same variety of plants; it will look superior to a patchwork of singles. Try to combine native decorative grasses, ferns and sedges in with your native rain garden plants, perennial wild flowers and shrubs to make certain the garden has a strong root mass which  will oppose corrosion and slow down weed growth.

• Specific trees, such as the ‘red maple’, ‘lament willow’ and ‘river birch’ can also be planted along the sides of rain gardens and are visually pleasant.

• Preservation of rain garden.  You should water new plants for the first few weeks, once the plants are established; the garden should flourish without further watering.

• Rain garden preservation is enormously low after the first summer of growth, only negligible weeding will be required, and these types of gardens hardly ever need fertilizers.
