Once you install your rain garden, you aren’t done. Maintenance plays an important role in ensuring the garden’s long-term health and usefulness.
The University of Connecticut College of Agriculture and Natural Resources has an entire program dedicated to rain gardens. It’s part of an extension program called Nonpoint Education for Municipal Officials (NEMO). Check out their concise summary of short and long-term rain garden maintenance, which includes a 3-minute video from NEMO Program Director, Dr. Michael Dietz.
