around your pond. Shallow and Bog Gardening
your pond will give it a finished look. You can hang
a picture on a wall by itself but put a frame around
it and you have a masterpiece. This goes for your pond.
Put an edge around it and it stands out and calls to
you to notice it. Edging will also secure your pond
liner beneath it.
are many types of edging. Raised edging or tilting the
edging slightly upward will help to discourage surface
runoff from entering the pond. Your edging can be extended
over the edge of the water by 1-2 inches to conceal
the liner from the sun and your view, making it more
attractive. Mortaring the stone or brick edging will
provide a safe and secure edge. Brick or cut stones
gives a formal look to your pond. A mixture of edging
can create an informal look to your pond. Plants can
be used to cascade over the edges to give a soft natural
look. If you use plants, leave an area where you can
walk close to the water. The use of plants can be inexpensive
and easy to install. Place your plants far enough back
from your pond's water edge so that when they cascade
over the edge they won't cover too much of the water
surface. Keep them trimmed back. You can grow grass
up to your pond's edge but keep it and all the clippings
out of your water. Dwarf and low-growing conifers, evergreen
ground covers and spreading broad-leaved evergreens
make for a satisfactory edging for your pond. I have
tall ornamental grasses growing behind my pond with
smaller grasses toward the sides. This allows me to
see my complete pond from the house and deck. The taller
plants are used for a backdrop and are reflected in
the water on sunny days. You will get ideas from visiting
other ponds and you can see many ponds in one day by
going on a pond tour.
I hear someone talking about water gardening I immediately
think of bog gardening. What is a bog garden? Mr. Webster
describes a bog as: wet, spongy ground; small marsh
or swamp; to sink down. Gardening is where you want
to grow plants. For the people with a swampy, wet area
all they have to do is plant any plant that likes water.
People who do not have this kind of area in their yard
can create one. A bog garden at the edge of your pond
is an added enjoyment. A true bog garden provides very
acidic conditions for plants. They are usually filled
with a mixture of half peat and half sand. Since a bog
garden is filled with soil, it should be separated from
your water pond. There are two types of bog gardens.
An Independent Bog Garden and Integrated Bog Garden.
An Independent Bog Garden is where the bog garden is
separate from the adjacent water garden. This is done
with a soil berm (raised edge) under your liner. This
garden must be watered separately. An Integrated Bog
Garden will allow the water to seep slowly through a
permeable layer between the adjoining pond and bog garden.
This permeable layer could consist of stacks of rocks
or soil between the two ponds. If the pond is kept full
then your bog garden will stay moist. A bog garden is
constructed just like a pond. You dig your hole any
size or shape you want. Make your bog garden about 12
inches deep. Extend your water pond liner under the
entire area so that the water will not seep out and
create dry soil. You must poke very small holes though
your liner so that aerobic conditions are not created
in the soil. Add your soil and wet down. You can also
make a bog garden with any shallow preformed container.
