Real World Gardener Creating Rain Gardens in The Good Earth

THE GOOD EARTH

Rain Gardens or Flood Mitigation.

Rain isn’t always reliable so rather than letting it flow into the stormwater especially when there’s a deluge, there are ways to let slow the water. Bog%2Bgarden%2Bon%2Bnature%2Bstrip.jpg

Of course there’s rainwater tanks, but you may need more than what they can hold. 
You need to change your thinking and work out a way to keep water in your garden longer.
Let’s find out more. 

I'm talking with Margaret Mossakowska, director of www.mosshouse.com.au 
Slowing the rush of water when there’s a deluge, will prevent your drains from backing up and possibly flooding your house. 

  • You can create rain gardens, wetlands or bog gardens.
If you have a spot in your garden where water likes to gather after rain, that's a good spot to create a bog garden.  It doesn't have to be any deeper than 10cm.
There are many Australian natives that would suit to grow in a bog garden.
Plants that suit for this situation are 
Marsh Flower (Villarsia exaltata), 
Purple Loosestrife (Lythrum salicaria), 
Tassel Sedge (Carex fascicularis), 
Jointed Twig-rush (Baumea articulata) and Water Ribbons (Triglochin procerum).

Rain gardens are a filtering garden and aim to slow water from leaving your property.
Think of all that water gushing out of your downpipe going to the storm water, when instead, it could be passing through a rain garden.
Choose any container, such as half a rainwater tank, or any sort of large plastic container.
Have an overlow at least half way up rather than letting the soil at the top float away.
Put in lots of sand at the bottom with soil/compost on top. The rain should just percolate through this soil rather than rushing down the drain.
Reed and native grasses suit to be planted in this type of garden.
There’s a choice of rain gardens or bog gardens, it’s up to you.
