A rain garden is a good way to divert rainfall and storm runoff to another place more desirable. There are two types of rain gardens – under-drained and self- containing. Which type depends on the volume of water that needs to be diverted, what your existing soil is like and how much you can afford. To be effective, a self-contained rain garden should be able to divert one inch of water within a four hour window. A under-drained rain garden should be able to divert heavy storm water within a two hour window. In both rain garden systems the ground needs to be excavated to a depth of, ideally 2' – 3' in depth, but a minimum of 8” and planting materials are best started when they are small so they can adapt to the growing conditions over time, as some times the area will be wetter then the norm.
A rain garden is a very attractive way to hide a draining system that can last for years and with the right planting materials it will attract birds and butterflies. It can be used to show off native plants of the region or be planted every year with annuals for a cottage garden look.
