Rain Gardens are an approach to rainwater management that can prevent flooding and erosion and turn stormwater problems into water supply assets by slowing run-off and allowing it to soak into the ground. Rain gardens are not ponds, they are a shallow basin fashioned to collect rainwater long enough to absorb into the ground. They are usually planted with native vegetation with deep roots that are hardy during both wet and dry seasons. These native plants are attractive, require little maintenance and help to purify the water. Plants in a rain garden add color to the landscape throughout the year and attract beneficial insects, butterflies and birds which are essential to the survival of our ecosystem.
Frequently Asked Questions
Does a rain garden form a pond:
No, the rain water will soak into the ground and is dry between rainfalls.
Are rain gardens a breeding ground for mosquitos?
No, mosquitos need 7-12 days to lay & hatch eggs, and standing water in the rain garden will last for a few hours after most storms. Mosquitos are more likely to lay eggs in bird baths (without a moving water fountain, storm sewers and laws than in a sunny rain garden. Also, rain gardens attract dragonflies, which eat mosquitoes!
Do rain gardens require a lot of maintenance?
Rain gardens can be maintained with little effort after the plants are established. Some weeding and watering will be needed in the first 2 years, and perhaps some thinning in later years as the plants mature.
