What are submerged water
Submerged water plants can be divided into two main types.
- Underwater plants that grow with their foliage
totally submerged underwater, such as Eel grass (Vallisneria).
- Emergent water plants with foliage both under the
water and also on or above the water surface, such as Water Milfoil
The foliage of
the two types is very distinct, with the underwater foliage often thinner and
more delicate. This foliage tends to
break more easily and for some of the underwater plants, allows them to drift
and regrow in other parts of the pond.
Care should be taken when selecting some varieties. Some varieties of submerged
water plants, that have been popular in aquarium's, have become
troublesome weeds in natural waterways.

state departments for further information.

and can cover large surface areas.
Why do I need submerged
Green water algae control.
water plants compete for the same nutrients, minerals and salts
as algae. Most are heavy feeders and
absorb through their leaves and roots thereby effectively starving out the
algae. The emergent foliage also
reduces sunlight penetrating the pond water and so shades out the algae.
Providing oxygen to the pond water.
plants are often referred to as oxygenating plants, providing oxygen to
the water during the day.
Shelter and protection.
water plants, particularly the emergent types, provide shelter
and protection for aquatic life, creating areas for the fish to lay their eggs and
spawn. Smaller fish also have a better
chance of survival as they provide excellent place to hide from the larger
Filtration and pond health
water plants play a vital role in improving water quality and
clarity. The leaves and roots act as
nutrient sponges, removing potentially toxic elements. Submerged water
plants help to create a healthy balance with animals, happily sharing
the same resources in a confined pond environment.
you wish to guarantee pristine water clarity you need to incorporate a
biological filtration system into your pond design. Click on the following link for

varieties produce trailing runners that grow into new plants that can root
themselves elsewhere in the pond.
Care should be taken particularly with earth filled ponds as they
could be overrun by the more vigorous varieties.
