Wet Garden

Asked April 12, 2018, 4:18 PM EDT

I have many garden around my home, but one in front stays wet for at least 3 - 4 days after it rains. It is located between my house and driveway in front and it gets about six hours of sun each day. Nothing seems to grow there, including grass. I want to convert it to a rain garden, so can you please tell me if I did out the soil about 12" and fill it with small stone and then build a 12" Soil layer over that, would that make a difference for draining? Also, what kind of flowering plants would you recommend for this? I would like nice flowers from spring to fall. The size of the area is approximately 30' x 10'.

It sounds like this particular area might not be suitable for a rain garden if the water stays standing in it for 3-4 days. Water in rain gardens should soak into the soil within 24 to 36 hours. Here is good basic information about the site characteristics that are ideal for a rain garden. https://extension.umd.edu/sites/extension.umd.edu/files/_docs/RainGardenFactSheet_0371.pdf#overlay-c... In your situation, we recommend that you contact the University of Maryland Water Restoration Program, to see if there would be other options besides a rain garden.
