Ready for Rain Peterborough
What is a rain garden?
A rain garden is a beautiful and unique piece of infrastructure that is used to capture and slowly dissipate rainwater from storm events into the ground. Generally they are populated with hardy drought tolerant species that require minimal maintenance. Rain gardens can come in many different forms, allowing them to be adapted for any need or situation.
Why use rain gardens?
Rain gardens can be a useful tool for managing urban runoff. Stormwater carries water from yards, streets, parking lots, and rooftops and often deposits them directly into local rivers and creeks. By creating rain gardens we can improve local water quality, decrease flooding, improve groundwater recharge and improve local habitat.
What makes a rain garden different from regular gardens?
Rain gardens are bowl or saucer shaped and designed to capture water from the surrounding landscape. It’s not just a typical garden though – they are designed with deep loosely packed soil and gravel specifically designed to maximise the amount of water that can be captured and stored within the garden. They can also assist in solving wet-spot problems where water is already collecting.
Are rain gardens breeding areas for mosquitoes?
Rain gardens are designed to rapidly capture and dissipate water from storm events. While mosquitoes require a number of days to reproduce, a rain garden will not maintain proper conditions for mosquito breeding. Traditional storm water infrastructure such as storm water ponds, or clogged eavestroughs are actually more likely culprits for mosquito breeding areas.
Do rain gardens require much maintenance?
Initially, a rain garden may require some watering. Rain gardens take advantage of the wide range of conditions that native plants are able to survive in. With deep root structures they can survive extremely dry conditions. The majority of maintenance comes in the form of removing some debris following very large storm events.
How big does a rain garden need to be?
Rain gardens come in many different shapes and sizes. They should be designed to capture any water that flows into them within a 24 hour period. Any water that is captured and remains on site following a storm will have a positive impact on our local water bodies.
