Using Turf For Rainwater Gardens

Using Turf For Rainwater Gardens

An option that works well for filtering water and reducing runoff in rainwater gardens is turf, within and surrounding the garden. In a study from the University of Madison-Wisconsin in America, they show that turf produces less run off than plants.

EMPIRE™ Zoysia Turf

A great lawn variety to use for rain gardens is Empire™ Zoysia turf. Being very low maintenance and very drought tolerant it fits in well with the rest of the plants in this article selected for the rain garden.

Empire™ Turf has also been used at the Ozbreed trial gardens as a filter in our dry river bed and has thrived in the wet and dry conditions.

The fact that it needs very little fertiliser to look great will suit rain gardens too; any nutrients that are used will be absorbed by the leaf and root zones.

Using Lomandra and Dianella plants in Rain Gardens

Using Lomandra and Dianella plants in Rain Gardens

Lomandra longifolia species will tolerate the dry periods well, it is the wet periods you have to worry about if you are in a high rainfall or humid area or if the plant is in a depressed area of the rain garden. 

Lomandra for Rain Gardens

It may get root rot or other fungal diseases, so unless you are sure, it is best to go for plants like Shara™ Lomandra a Lomandra fluviatilis or Katie Belles™ Lomandra hystrix as these varieties handle wet feet and humidity a lot better as well as dry conditions. 

Pennisetums such as Nafray, Purple Lea and the new Pennstripe are also suitable for rain gardens and they add a great native look and feel.

Dianellas are not generally the best for rain gardens as they aren’t very tolerant of wet feet, when using them you have to be careful with which species you use. One species that tolerates wet feet is Dianella caerulea. 

Some of the best of this species are King Alfred® Dianella, Little Jess™ Dianella and Breeze ® Dianella. If you want the finer leaf of a Dianella revoluta, which usually does not handle wet feet, use Revelation® Dianella as it handles wet feet much better than common revoluta.

Plants For Rain Gardens – By Katrina Layt

Plants For Rain Gardens

By Katrina Layt

A Rain Garden is a very useful way of removing excessive nutrients from water runoff before they enter our waterways. It will keep most of the water where it falls first as well as reduce erosion and pollution.

Rain Gardens - Melbourne

Example (Above) of a rain garden from raingardens.melbournewater.com.au

While a lot of people know about the technical side of things when it comes to gravel size, soil mixture and the number of slits needed in drainage pipes, they often fail at selecting the right plants for the job.

It’s recommended that you use indigenous plants particular to an area and this is great so long as you don’t forget to use plants that can handle wet feet as well as dry conditions. Australian native plants fit the bill perfectly, but make sure you choose the right ones.

Before water travels through to the storm water system and eventually into our waterways, a rain garden will catch water from rooftops and other hard surfaces to filter through its layers of plant roots, sand and gravel.

This is becoming a popular industry practice as the benefits are worth it. A reduction in waterway pollution as well as algal growth will be attributed to using rain gardens in some form, whether it be in ground, above ground, a swale, a retention basin, large or small.

Every rain garden helps and should certainly be considered in any new or existing development. With the recent flooding, if every house had a rain garden or just more gardens and less hard surfaces in general, flooding impacts could have been lessened.

Generally rain gardens aren’t always wet, only when it rains. The water is drained out quickly after rain because of the high drainage properties of the sand and soil used (this varies depending on the mix).

Rain gardens still do have more rain water coming through than normal gardens, so there are times when they will be inundated with water, that’s why certain plant species will not survive. They are dry for a large period of the year (depending on your rainfall patterns) so drought tolerant plants are still needed for the optimal low maintenance garden. The rain that does come through will be plenty for these selected plants here …read more
