Planning a Water Garden...Can You Dig It?
We have just finished putting in another water
garden. This one is in the butterfly garden, just
outside the bay window in the living room.
Why there? Because, it will be safer for the fish
and butterflies being closer to the house and we
are able to better enjoy the small, beautiful
world that was created from the window.
The water garden is quite simple to create, and
will take a good afternoon of labor.
The basic shape of the pond can be determined by
using a garden hose, it is flexible and can be
moved easily until you are happy with the shape.
Be sure that there are no sharp corners.
It is advisable to include shelves for plants.
These shelves should be 10 to 12 inches deep, and
a foot below the surface of the water and slope
very slightly to the outside of the pond this
prevents plants from sliding into the pond.
The pond should be 18 inches deep. If you are
going to keep Koi, the pond should be at least 3
feet deep. The bottom of the pond should slope in
one direction, so organic waste can be more
easily removed, though the top of the pond should
be level.
Next you will want to line the pond; EPDM rubber
is durable and easy to work with. The liner
easier to install if it is warm, so let the sun
shine on it for a few minutes before unrolling
it.
When sizing the liner the length of the liner is
the length of the pond at longest part + 2 times
the greatest depth + 3 ft. The width of the liner
is the width of the pond at widest part + 2 times
the greatest depth + 3 ft.
The liner should be cushioned by at least a 2
inch layer of sand or other soft, protective
material after you have cleared rocks and roots
from the hole.
Excess liner should not be cut off until it is
well anchored all around the perimeter and the
pond is filled with water.
Don't be in a hurry to add fish, until you have
the pond stabilized and your plants in place. Do
not add rocks to the water of your water garden,
unless you know for a fact that the rocks that
you are using will not leach chemicals into the
water that will kill your plants or fish or
effect the ph levels of your garden.
Check the pH and nitrite level, pH between
6.8-7.4 and nitrite 0. Check salt level if you
are experiencing problems stabilizing the pH.
Measure the pH and nitrite level every few days
at first, every few weeks later in the season
when the pond has stabilized. Do not disturb the
biological filter material when cleaning your
filter, so the bacterial colony can establish
(use only de-chlorinated water to clean the
filter).
Install the pump and filter, your home and garden
store should be able to tell you how big of a
pump you need. Be sure to take the dimensions of
you pond with you shopping. We have a sump pump
in our pond.
When cleaning debris from your water garden,
consider a pool net as opposed to a pond vacuum,
you really want to limit the amount of scraping
on the rubber to increase the life of the rubber.
Your plant nursery will have water plants to add
to your garden or if you live near a fresh water
lake you may like to gather them yourself (law
allowing). Plant your water plants in pots and
set them on your plant shelves in your pond so
that the pots are under water. You may have to
hold the pot until the soil is saturate with
water to keep the pot from floating up.
Add beneficial bacteria (such as MicrobeLift) to
jump-start the biological cycle to help prevent
water quality and algae problems.
Now you are ready for the fish. We use your basic
10 cent feeder gold fish. They can be purchased in
a variety of colors and do very well in a water
garden. In our last water garden we had the same
fish for two years and they grew to be of some
size.
You could also use Koi if your water garden is
large enough. They are a larger investment and
higher maintenance.
Be aware that your fish are prey to a number of
things in the outdoors, birds and raccoons being
at the top of the list.
The birds are relatively easy to deter by
stringing monofilament from tree to tree or from
the house to a tree. Birds don't understand what
is reflecting the sun so oddly and won't fly
under it.
Raccoons are another matter, they are attracted
to the water to wash their food, finding the fish
is a bonus.
Setting up a motion detector to a sprinkler head
system is usually enough to startle the raccoon
before he goes swimming in your water garden.
