Top 10 Questions About Water Gardening

Many people enjoy the serenity that a backyard
garden pond
provides. And while these garden areas offer peaceful
sanctuaries to those that have them, they can also create frustration when
gardeners come across issues with which they’re unfamiliar. And that’s where Gardening Know
can help. We get lots of questions about gardening and strive
hard to provide answers to the best of our knowledge. Here are some answers to
the 10 most commonly asked questions about water

1. What is the best way to clean pond?

It’s important to clean
a garden pond
in a way that is safe for plants and fish. The easiest
way to keep it clean is to install a filter and pump. You’ll only need to change
the filter medium once in a while.  Just
be sure there is an intake screen to protect fish. Without a filter system,
cleaning the pond by hand once a year should be adequate. Remove debris by hand
or with a net. If the water is still pretty dirty, drain the pond and give it a
good scrubbing. You’ll have to move any fish and plants briefly to do this.
Keep fish in water and plants moist.

2. How to grow water lilies in a container?

First, choose the appropriate plants. Hardy water lilies are
best for colder climates and tropical varieties for warmer garden ponds.
Prepare plastic pots for water lilies by poking holes in the bottom and sides
and filling within a few inches of the top with soil and aquatic fertilizer. Plant
the water lily
rhizome in the pot with its eye upward and cover it
with pea gravel to keep soil in place. Place pots in a pond to a depth of about
six to 18 inches (15 to 45 cm.), depending on the variety.

3. How do I care for my garden pond plants over the winter?

your pond plants
depends on where you live. If you have cold
winters, your pond plants will need to come out for the season. Remove them and
keep them in a plastic tub or aquarium of water indoors with adequate lighting
and warmth. Let the roots stay bare in the water and when the plants begin to
sprout again, replant them in pots and set them back in the garden pond.

4. What should I do to winterize my pond?

For colder climates, some winterizing
is important for a healthy garden pond
. Plants should come out and
stay in water indoors for the winter with adequate light and warm temperatures.
If you don’t get hard freezes and have hardy pond plants, they can stay in the
water for winter. Give the pond a good cleaning by removing debris. Unless it’s
really dirty, changing out the water isn’t necessary. For fish, start
decreasing their feeding as temperatures get down to 50 degrees Fahrenheit (10
Celsius). If a hard freeze is a risk, use a water pump to keep part of the pond
ice-free so fish will survive.

5. Are there any water container shade plants?

Water plants that tolerate some shade include hardy water
lilies, arrowhead, bog lily, cardinal flower, parrot’s feather, pennywort,
primrose creeper, water clover, and watercress. All plants need some sunlight,
so if you have deep shade, keep a shade-tolerant plant in a container and move
it to get some occasional light.

6. What plants will survive flooded areas?

are great options for areas of gardens that are vulnerable to
flooding, as they can grow in wet and dry conditions. Examples include water
iris, Siberian iris, cardinal flower, pitcher plant, rose mallow, astilbe, blue
vervain, sweet woodruff, daylily, monkey flower, Indian grass, northern sea
oats, cattail, elephant’s ear, and water hyssop.

7. What types of plants grow well in ponds?

that grow in ponds
are those that thrive in water. Try the classic
water lilies, which come in both hardy and tropical varieties. Other popular
choices are common waterweed, various types of iris, water hyacinth, marsh
marigold, sweet flag, parrot’s feather, water hibiscus, pickerelweed,
elephant’s ear, swamp sunflower, and water hyssop.

8. How to install a garden pond?

a garden pond
can be a big job. First select a location with four to
six hours of sunlight and that will fit the size you want for a pond. Dig out
the pond to a depth of about two feet, leaving a shelf of only one-foot depth
around the edge for plants. Line the pond with waterproof plastic or pond
liner. If using a filter, install it before adding water. Fill the pond with
water and check the function of the filter. Let the water sit for about a week
before adding plants and fish. Landscape the edges, add in appropriate fish and
plants, and enjoy your work.

9. Should you remove cattails and, if so, how?

in ponds or drainage areas can be a nice landscaping element, but they can also
grow out of control. In a drainage area, they may get so thick as to impede
water flow, while in a pond they can crowd out other plants. Where they are
native, cattails improve the health of these areas. If you do need to thin
them, though, you can dig them up by the root. This is physically demanding and
may not be possible for a large area. Another option is to drown cattails by
cutting them back until they are submerged.

10. Is duckweed invasive in ponds?

grows on the surface of ponds and can quickly become invasive and detrimental
to the health of the pond. It grows rapidly, covering the surface and blocking
necessary light and oxygen, which can result in the deaths of other plants and
fish. Prevent duckweed growth by regularly removing organic material, like
leaves, from the bottom of the pond. Duckweed thrives in nutrient-rich water.
You can also use a net to physically remove duckweed.
