Product Information

Native plants are always recommended for rain gardens as they are well adapted to local growing conditions and support local wildlife, including birds and butterflies. A rain garden is dry most of the time. It usually holds water only during and after rain, and they drain within 12 to 48 hours. A rain garden planter is filled with layers of drainage clay pebbles/shingle, and a specialist free draining growing medium. They are isolated from the water management system by a geotextile layer. The planter is lined to form a waterproof seal to retain the stormwater for regulated slow release. If you’d like to speak to a member of our landscape or communities team about implementing something similar in your community, don’t hesitate to get in touch: Based on trial data, the narrower diameter is recommended to limit the flow out of the planter to a reasonable level to maximise the potential for flood storage, especially where extra storage was provided by the geocellular storage. One hour after a rainfall event begins, up to 0.75m 3of water can drain from the bottom of the planter.

Water Quantity - Controlling the quantity of runoff to support the management of flood risk and maintain and protect the natural water cycle. Ensure that the lowest point of the rain garden allows overflow water to access adrain, or other rain garden element In this way, the whole garden could be considered a rain garden. However, more commonly, the low-lying area or dip itself, is defined as the rain garden. Benefits of rain gardens Depending on the choice of storage layer,an additional 0.62-1.1m 3of water can be stored in the planter before it over flows.This means that over an hour following the beginning of a rainfall event, between 1.37 m 3 and 1.85 m 3 can enter the planter before water drains via the over flowpipe.To properly locate the rain garden, first, need to know where the rainwater comes from. Gutters are one of the main sources. If one of them is connected to a larger roof area, it will carry more water to the land. Plants for rain planters have to be able to tolerate some wetness at the root zone as well as grow in more normal conditions. If you’re feeling inspired to now create your very own Green Roof, make sure you let us know on social media! Stay tuned for exciting projects on the horizon. If possible, place the rain garden on a gentle slope. The slope should be less than 12% and need to make sure the rain garden is not located over water pipes or other underground infrastructure.

Some shrubs such as Cornus sanguinea or even trees, such as Betula would be suitable for a large planter. SuDS planters, or stormwater planters, are a sustainable stormwater management solution with their intelligent internal drainage system. With both bio-retention and additional internal storage, these planters are an innovative solution to property level retrofit SuDS and can work out as much less expensive than most groundwork interventions. Theseplanters arean attractiveadaptation of Sustainable Drainage Systems (SuDS) which slows surface water flows, Even if you don’t have room fora rain gardenyou can still implement sustainable stormwater management. Rain gardenplanters, or gutter planters, handle rainwaterrunoff from rooftops and operate like a rain garden inside a planter.Larch produces its own intrinsic preservative providing a very long planter life without the use of toxic preservatives. Add some gravel to the base of your planter and position the slotted pipe so that it drains down towards the outlet. Push the drainage pipe through the liner and connect up the overflow pipe. Seal up your pipes with silicon and tape. Add the remaining gravel to cover the pipes and top with permeable membrane to stop rainwater washing the soil out. Add a layer of sand and then fill with a mix of soil/compost to sand in the ratio 4:1. 5. Aim the downpipe Plant with a variety of hardy perennial plants which can tolerate dry periods as well as short periods of flooding. Choose a mix of plants which can provide interest year-round and help to attract pollinators. These planters are particularly useful in areas where a significant amount of rainwater travelling from the rooftop or other impervious surfaces flows directly into a drain causing flooding on one's premises.
