how to rain garden
Create the rain garden bybuilding a berm in a low spot in the yard, then build swales to channel runoff from the gutters and higher parts of the yard. The water is then absorbed into the soil through the network of deep plant roots. Use a mix of plants adapted to your area and to the different water depths.

How to build a rain garden?
If the rain garden is on a slope, you can pile some of the excavated soil into a berm on the low side to retain the water. For stability, stomp the berm soil down well and make the base at least 2 feet wide and the top at least 1 foot wide. The peak of the berm should be at least 6 inches higher than the water level when the rain garden is full.

How do you keep mosquitoes out of a rain garden?
Use the loose soil to create a low berm on the lowest side of the rain garden. As water flows into your new rain garden, the berm will help hold it long enough to seep into the soil. If you make the garden deeper than 6 inches, mosquitos could become a problem because it will take the water longer to completely percolate down and evaporate enough.
