Episode 174 Building a Garden Pond

On today’s episode I talk about building a pond for your garden.  The garden pond is such a great way to encourage diversity not only in the forms of wildlife it attracts but also in the form of planting surfaces and microclimates it creates.

*Locating the pond.  Where does it make the most sense?  It needs to be accessible by animals and in a location where the water is easily usable. 

*Three ways to make the actual water holding device.

  1.  Straight dig
  2. Liner – hard or film.
  3. Gley – either through pigs, manure/paper or bentonite clay.

 With all methods you have to dig a little at least to start.  Method 3 requires just cursory digging if you use pigs. 

*Details on digging the hole, building a dam and making sure its level.

*As soon as is practicable you need to plant on the dam and on the ground around the pond.  The purpose is nothing more than to prevent erosion and runoff.  Plant something that grows fast but is annual. You want to be able to plant more thoughtfully later. 

*Adding organic matter to the water to get things going.

*Plantings – you get into a whole new category of plants.

  • Edibles – watercress – a member of the brassica family – spicy green leaves.  High in vitamins and a cancer fighter.
  • Rice
  • Water lily and lotus – both have edible parts.  The leaves of the water lily sits on the water, but the lotus rises and its leaves sit up to four feet above the water. 
  • Cattails
  • Duckweed – livestock

*Fauna

  • Frogs come on their own as do crayfish dragonflies, water spiders, etc. 
  • You can add some fish – depending on the size all the way from goldfish (make excellent bait) all the way up

    Jason,
    I dug out a 20x7x5 pond a few years with a skid steer loader and I have been putting grass clippings in it ever since trying to get the “gley” effect. It works ok, and it holds water for a time but then dries up unless we get consistent heavy rains. One thing I learned especially for gley is that steep sides wont work too well because you have to have the layers of grass thick on the wall sides, so lesson learned there. Im hoping that over time it will start to be more concave shape instead of so steep. Interesting segment.

    Jason,

    Awesome content as usual! Was wondering if you are concerned about algee bloom and possible oxygen kill with all the organic matter you are putting in the pond?

    Mine is really suffering during the drought we are having here.  So I’ve been gleying it with straw much the same way.  I need to fence some pigs in there!

    The thought has crossed my mind.  I really haven’t added too much.  Doing it in a measured pace. 

    The lilies and lotuses should shade out some of the algae – I hope!Jason
