Rain gardens are carefully engineered, but you don’t need to be an engineer to build one! Follow these basic steps and consult the additional resources at below and you can enjoy your very own rain garden for years to come. Below is a list of supplies and tools you will need. The rain garden icon next to a step indicates that tools, videos or more information can be found on the free Rain Garden App by UConn Clear available from the App Store or Google Play. Building a rain garden is a simple and rewarding task that will improve your own property and the natural environment.
Sizing a rain garden to hold runoff from a one inch rain storm is a good target, although smaller rain gardens can still make a big difference.
Ideal size for your garden:
Measure the area (length x width) of the roof or driveway that your rain garden will collect water from in square feet and then divide by 6. This gives you the target size for your rain garden in square feet.
