Creating a rain garden is an excellent way to manage stormwater, improve your landscape, and support local wildlife. September is a perfect time to start planning and establishing your rain garden, as the weather is still mild and the soil is often moist from late summer rains.
What Is a Rain Garden?
A rain garden is a shallow, planted depression designed to absorb and filter rainwater runoff from roofs, driveways, and lawns. It helps reduce flooding, prevent water pollution, and create a habitat for birds, bees, and butterflies.
Steps to Create Your September Rain Garden
1. Choose the Right Location
Select a spot at least 10 feet away from your home’s foundation to prevent water damage. The area should have good drainage and receive at least 6 hours of sunlight daily. Avoid low-lying areas prone to standing water or with heavy clay soil.
2. Assess and Prepare the Site
Use a shovel to remove grass and a few inches of soil from the selected area. Mix in compost or organic matter to improve soil permeability. Mark the perimeter of your garden with stakes and string.
3. Design Your Rain Garden
Shape the garden with a gentle slope toward the center or one side to facilitate water flow. Create a berm around the perimeter if necessary to contain water during heavy rains. The depth should be about 4 to 8 inches.
4. Select Native Plants
Choose native plants that tolerate both wet and dry conditions. Examples include swamp milkweed, little bluestem, and Joe-Pye weed. Group plants with similar water needs together for best results.
5. Plant and Mulch
Arrange plants according to their mature size and water needs. Dig holes twice as wide as the root balls, place plants, and backfill with soil. Apply a layer of mulch to conserve moisture and suppress weeds.
Maintenance Tips for Your Rain Garden
In September, your rain garden might need some initial watering, especially if dry spells occur. Remove weeds regularly, and prune dead or damaged plants. After the first few seasons, your rain garden will require minimal upkeep.
