If you are reading this then you are probably interested in
knowing how to build a backyard lily pond. I wanted to build one for at least five
years before finally doing it. The wait was not necessarily due to my laziness
or fear of messing up. It took that long before I could have my fence done. It
was a new development and took three years before I had all my neighbors – four
of them. Two at the sides, two at the back.
Anyway, lets get on with the pond venture. I do not have a
large backyard. In total it is 1000 sft area. I have existing gardens, both
vegetables and flowers. Hence it was very important for me to set my mind on a
pond of right size – not too small so that it has no effect on my overall
garden, and obviously not too big so that I am left with no space for anything
else. So, after lots of pondering and measurements and drawings and thoughts I
decided on a 8 feet by 5 feet pond, with about 19 inches of depth. I wasn’t
trying to build a Koi pond, just a lily pond with a few small fish. The local code
allows only about ~19” before I would need permission (and fencing around the
pond etc.).
Step1:
The first thing I did was to find out the exact spot where I
would want the pond to be. I took some ropes and placed it the way I wanted the
pond’s shape to be. I was not only limited by my small yard but also with the
fact that I have a 14 feet trampoline in my backyard that kids loved to play
on. Unfortunately the only spot where I could have the pond was next to the
trampoline, limiting my option with the width of the pond. I had to keep enough
room for walking space between the pond and the trampoline so that I could not
only perform regular maintenance of the pond but also to allow me to have a way
to circle around my full garden. Admittedly I drew several possible sizes and
location of the pond and finally took the one that strike me to be the best. I
had to keep it slightly slim but I could compensate length wise. The other
factor that I needed to remember is the fact that it was supposed to be a lily
pond hence the sun requirement was much more than a fish pond. For good lily
blooms 8-10 hour direct sun is best. The selected spot got at least that if not
more (I have a south facing house and the part near the fence at the back of my
house gets tremendous amount of sun while the part near the house gets some in
the afternoon. This really works well for gardening as I plant shade loving
plants near the house and sun loving plants away from the house, which includes
flowers and vegetables.
Step 2: Digging.
Step 3: Building the pond: I had purchased a pond liner (15
x 10 – I believe) from local Home depot. I went for a thinner liner as it was
relatively cheap (around CAD 100) and seemed to serve my purpose. I had a lot
of carpet leftovers that the builders had left behind. I used them generously
to cover the whole inside of the pond so that the pond liner would not get in
touch with the hard soil underneath and get torn.
Placing the pond liner was a little difficult than I thought
it would be. Until then I was working alone as my wife had declared from the
very beginning of this project that she wanted to have nothing to do with it.
At this point I had to use up all the sweet words that I had stored in my
arsenal to get her sufficiently motivated to help me lay off the liner. It
turned out that the liner was a tad bit too big from my pond. However, I
decided not to cut any part of it. Instead I piled up some of the earth from
the digging around the pond to create a slightly raised edge and secured the
liner by heavy rocks that I had collected in advance. Whatever liner stuck out
I folded and tucked under the soil. Later I spread out gravel around the edges
which hid whatever part of the liner was still visible.
Step 4: Filling: This was the easiest part. I let it fill
out from the garden hose. Considering the relatively small size it took less
than an hour (~350 gallon). I purchased several water plants from the local
garden shop and placed them on the shelf that I created inside the pond. Next
came two hardy lilies that went in the deeper section in the middle. Finally
needed to ensure that this did not become a safe heaven for the mosquito larvae
as I was not planning to put any kind of pumps. Beside being a strain on the
electric bill they could also become a source of constant maintaining or
issues. I did not want any of that. So, I bought a bunch of feeder comets and
released them in the pond. Unfortunately the weather was sort of freaky and the
temperature fluctuated a lot causing some of the comets to perish. The water
went from crystal clear to cloudy due to abundance of algae growth. This was
expected as the pond was getting lots of sun and I had no floating plants to
cover the surface of the water. I did not want to buy floating water plants
because the lilies when grown would supposedly cover most part of the pond. I
continued to change about 50 gallons of water every other day to keep the algae
growth minimal. Seeing my effort not working I had to purchase some water
hyacinth. I bought four and released them in the pond. They started to multiply
soon and took care of part of the algae problem. I continued to do some water
change every few days and picked out all the visible algae and leaves or other
floating debris using a fish net attached to a long wood handle. The lilies
started to grow leaves in about a week. By week three there were at least a
dozen leaves on the water surface. After about four weeks the pond water became
crystal clear again. Among all the comets three survived the ordeal and are
currently growing big. I do not feed them absolutely anything. They feed on
whatever they find inside the pond. There has been no larvae on the surface of
the water so I am assuming they are gorging on them.
Step 5: Plants: Here are the plants I had after I was done.
Step 6: Final: This is what I had after couple of weeks of completion.
