I had an opportunity last week to work with a group of dedicated volunteers from a variety of agencies including the University of New Hampshire Cooperative Extension and some of my fellow Master Gardeners to create a rain garden.
The rain garden was for the Woodman Institute Museum which was dealing with dampness in the basement limiting use of that space.
After securing a donation of a professionally sized dehumidifier and installing new guttering, next on their to-do-list was a rain garden that would help divert water from three gutters on the back side of the building. Any runoff from the rain garden would then be cleansed of pollutants and diverted into the nearby storm sewer.
The soil was removed from the garden area and dumped on a tarp. The removed soil, compost, and green sand were mixed and then used to refill the space. After the initial removal of soil, the center depth measurement was 12″ and was refilled to 7″. The center was raked and the sides rounded prior to planting.
Once the plants were installed, mulch was put on top.
This is one of the three down spouts feeding into the rain garden.
The finished garden is quite lovely as well as providing a great service to a wonderful non-profit.
Note: If you or anyone you know are planning on creating a rain garden this size or larger, I’d highly suggest a piece of equipment to help excavate the space, mix soil and compost, and then refill. The very large backhoe used was able to complete the initial excavation easily but was unable to maneuver in the space to mix and refill. Translation – a lot, and I mean a LOT, of hand shoveling, wheel barreling and raking was required. 🙂
A list of plants used was not available at time of posting, but when I get access to it I’ll add it here.
Do you conserve water? Rain barrels, dry creek beds, or rain gardens on your property?
