RAIN GARDENS- Design and Installation

DESIGN AND PLANT CHOICES

Sedge grasses are great for wet areas of the rain garden

Check with online resources or landscape professionals for guidance on size of garden needed as well as proper depth. They also can help you determine how the water will enter your garden through draintile surface run off or dry creek beds. Once you have those figured out and sketch a shape for your area the plant layout process can begin. Keep in mind light conditions of the garden throughout the day as well as bloom times so that the garden will have a long period of interest. Some people choose to go all native or pollinator plants, mixed shrubs and perennials or all grasses. There are many resource lists online to help narrow down plant choices. Most planting plans are divided into zones based on where the water will be the longest.

Popular Plant choices:

Grasses: Fox sedge, Blue Zinger sedge, Feather Reed Grass and Little Bluestem

Perennials: Blue Flag Iris, Coneflowers, Liatris and Lobelia

Shrubs: Red Twig Dogwood, Bush Honeysuckle and Spirea

INSTALLING YOUR CLEAN WATER PLANTING

Ok, now we’re ready to get out the shovels and do some digging! Draw out the outline of your planting space with spray paint or use a garden hose so you can move it around to get the shape just right. Also outline the area that will need to be the deepest part of your garden to hold the water. Decide if you are OK with herbicide to kill the grass and plan to do your spraying at least 3 days ahead of digging. If you would rather go a natural route strip the sod off and use elsewhere in yard or flip it over to create a small berm as designed in your new planting area. After surface material is removed continue to dig out the flat bottom bowl to the depth you need and size you’ve planned out.

Next bring in the compost material estimated to incorporate into the bottom of the bowl and use a garden fork to manually dig it in or employ a tiller for mechanical help. After the soil has all been raked out you are ready to place the plants using the design for proper placement. Or if you have a lot of small plants you may want to spread mulch first and then put in plants after to insure no plant gets buried in the mulching process.

Use root pruning techniques to prepare plants for proper root growth, dig your hole and plant! Mulch should be a good quality type that is fibrous and meshes well to get so as not to float and disturb the plants in a rain event. Plan for around 2” mulch depth.

As a final step thoroughly water each plant to settle it into the soil, removing air gaps and providing necessary moisture for needed root growth. Follow a landscape professional watering plan for ideal plant health and establishment.

Step back, take a look and enjoy your accomplishment. You are now benefitting the birds, bees, family, neighbors and most importantly the future of clean water.
