When should you plant a rain garden?

Although a rain garden can be installed anytime the ground is not frozen, spring and fall are the best times to start your garden. In spring, the soil is easier to dig and the rainy weather means less initial watering.

Where should a rain garden be placed?

The rain garden should be located in a place that can collect as much impervious area (driveway, roof, sidewalks) runoff as possible. The best areas are generally where water naturally drains but doesn't hold water. It should also be located at least 5'-15' away from your home.

How do you build a rain garden?

Create the rain garden by building a berm in a low spot in the yard, then build swales to channel runoff from the gutters and higher parts of the yard. The water is then absorbed into the soil through the network of deep plant roots. Use a mix of plants adapted to your area and to the different water depths.

Do rain gardens attract mosquitoes?

Rain can be a valuable resource when managed properly. If not managed properly, storm water runoff can threaten homes, neighborhoods and even people's lives. Rain gardens do not attract mosquitoes as the water is typically absorbed within 48 hours which is not long enough for mosquitoes to breed. ...

Do rain gardens really work?

Rain gardens are effective in removing up to 90% of nutrients and chemicals and up to 80% of sediments from the rainwater runoff. Compared to a conventional lawn, rain gardens allow for 30% more water to soak into the ground. ... Because rain gardens will drain within 12-48 hours, they prevent the breeding of mosquitoes.

Can you plant a garden next to your house?

Be sure not to put the garden too close to your house, which will cast shadows; keep planting areas at least 10 feet away from the walls. Vegetables planted in the shade are less productive and may be more susceptible to disease and insect damage than planted in full sun.

Do the rain gardens have standing water?

No. Because rain gardens are shallow and are only built on soils with sufficient drainage, they are designed to dry out before mosquitoes can reproduce. Will my rain garden have standing water? Rain gardens are designed to infiltrate water in about a day.

What characteristics are necessary for a plant to thrive in a rain garden?

Criteria for Selecting Rain Garden Species

Plants that need full sun need at least 6 to 8 hours of direct sun during the growing season; plants that require shade cannot tolerate more that 3 hours of direct sun. The hours and angle of sunlight change with the seasons, too.

Which plants soak up lots of water?

10 Impressive Plants That Absorb Lots of Water

How deep can a rain garden be?

A typical rain garden is between four and eight inches deep. A rain garden more than eight inches deep might pond water too long, look like a hole in the ground, and present a tripping hazard for somebody stepping into it.

How much does a rain garden cost?

The cost of a rain garden can vary substantially based on size, location, plant variety, soil amendments needed, and availability of volunteers. Residential rain gardens average about $3 to $4 per square foot, depending on soil conditions and the density and types of plants used.

What is the difference between a bioswale and a rain garden?

The main difference is that the bioswale moves water to somewhere else in the garden, while also allowing some (but not all) of it to infiltrate. A rain garden is specifically meant to increase infiltration. Bioswales are often used to convey water to a rain garden.

How do you size a rain garden?

Go out to the area designated for the rain garden. Identify the section of roof that will drain into the downspout. Measure the length and width of this area. Take measurements of other hard surfaces such as driveways, parking areas, or sidewalks that may drain into the rain garden.

How much water can a rain garden hold?

If your rain garden (aka swale) is 10' wide and 8-1/2' long, its area (10' x 8.5') is 85 square feet. So at 12” deep, it will hold about 620 gallons of rainwater. If you dig it down just 6” deep, your rain garden will hold only half of that, or just 310 gallons of water.

What are the benefits of having a rain garden?

Filter pollutants from runoff, • Recharge groundwater, • Conserve water, • Protect guts, ponds and coastal waters, • Remove standing water in your yard, • Reduce mosquito breeding, • Increase beneficial insects that eliminate pests, • Reduce potential of home flooding, • Create habitat for birds & butterflies, • ...

How does water get to the plants in the rain garden?

A Rain Garden receives water from impervious (hard) surfaces such as rooftops, sidewalks, driveways and patios. The shallow depression of the garden holds the water so it can slowly infiltrate back into the soil as the plants, mulch and soil naturally remove pollutants from the runoff.

What are the different layers of a rain garden?

The rain garden consists of a vegetated or stone ponding area, a mulch layer, a planting soil layer, a sand bed, and a gravel base. The multiple layers work together to filter pollutants from water, allowing it to infiltrate into the groundwater supply uncontaminated.

Is it good to plant before it rains?

Plant Seeds Before It Rains

Dry soil is easier to work with than wet soil and seeds are less likely to rot in soil that doesn't stay soggy for prolonged periods. Add in a nice rain shower, and you won't need to drag out the garden hose to water your newly planted seeds.

Can you plant trees in a rain garden?

Most of the vegetation planted in rain gardens consists of shrubs and herbaceous plants, but you can also install trees in a rain garden if you wish. However, you must pick species that can adapt to the conditions present in or near the rain garden if you want to give the trees the best chance of thriving.
