Pond Plants Guide

Pond plants are an eye-catching decoration of ponds and gardens. They aerate the water tank, reduce the amount of algae, and help to achieve the biological balance so typical for natural ecosystems. Pond plants keep the water clear.

Bog or shallow pond plants are the group that we plant in the shore zone of the pond. These plants grow beyond the surface of the tank. We plant them at a depth of several cm to 150 cm. These plants grow above the surface of the water. Rhizomes and roots are submerged while larger parts of the plant, their leaves and flowers, grow over the water.

Plants can be planted in ponds in special caves, in pots or between stones.

Small plants should be put shallowly, so the larger part of plant is above the water. Later, when they grow up, we can transplant them to a permanent place, much deeper into the pond.

Trimming

If you bought loose pond plants please proceed as follows:

  1. Trim the leaves in order to reduce transpiration. It is very important. Plants will be healthier and their growth will be lighter and faster.
  2. Put trimmed plants in temporary pots with a diameter of 10-15 cm and set on shallow water. At this time you can fertilise them. Prepare a light solution of fertiliser and spray the leaves for a few days.
  3. After about 2 weeks when plants start growing you can replant them to permanent place.

Leaves of the following plants should be trimmed up to the half:

  • Phragmites australis – Common Reed
  • Schoenoplectus Tabernaemontana – Softstem Bulrush
  • Typha angustifolia – Small Reed Mace
  • Sparganium erectum – Branched Bur Reed
  • Acorus calamus – Sweet Flag
  • Iris pseudoacorus – Yellow Iris
  • Iris sibiricus – Siberian flag
  • Carex sp. - Sedge Grass

The following pond plants should not be trimmed:

  • Equisetum hiemale – Horsetail
  • Comarum palustre – Purple Marshlocks
  • Veronica beccabunga – Brooklime
  • Mentha aquatica –  Water Mint
  • Calla palustris – Water Arum
  • Glyceria aquatica – Great Manna Grass
  • Heleocharis palustris – Common Spikerush
  • Solanum dulcamara – Nightshade
  • Juncus effusus – Big Twister

These plants have either evergreen leaves such as Horsetail, or have a lot of strength of growth and ability to quick adaptation to a new environment, thus cutting their leaves would be meaningless.

Leaves of the following plants should be trimmed completely:

  • Alisma plantago-aquatica – Water-Plantain
  • Caltha palustris – Marsh Marigold

Cutting leaves before planting is necessary because plants would lose them anyway. The new leaves will be fresh, healthy and brilliant.

Planting depth

Depth of planting Bog Pond Plants is a very important factor for theirs proper growth.

Bog plants planted on shallow water will grow forever but planted too deep - will rot.

The following plants should be planted on shallowly water (up to 20 cm):

  • Alisma plantago-aquatica – Water-Plantain
  • Caltha palustris – Marsh Marigold
  • Iris sibiricus – Siberian flag
  • Equisetum hiemale – Horsetail
  • Comarum palustre – Purple Marshlocks
  • Veronica beccabunga – Brooklime
  • Mentha aquatica –  Water Mint
  • Calla palustris – Water Arum
  • Caltha palustris – Marsh Marigold
  • Solanum dulcamara – Nightshade
  • Juncus effusus – Big Twister
  • Carex sp. - Sedge Grass
  • Lythrum Salicaria - Purple oosestrife

It should be mentioned that some plants from the above list such as: Purple Marshlocks,  Brooklime, Water Mint and Water Arum, are planted shallowy, but they grow "horizontally", ie, they float on the water growing towards the free surface of the water, deep into the pond. While Nightshade can swim on the water, as it finds any support, it begins to climb up.

The following plants we can plant deeper - up to 20 - 80 cm:

  • Glyceria aquatica – Great Manna Grass
  • Heleocharis palustris – Common Spikerush
  • Sparganium erectum – Branched Bur Reed
  • Acorus calamus – Sweet Flag
  • Iris pseudoacorus – Yellow Iris
  • Butomus umbellatus Flowering Rush

The following plants can grow very deep - 150 cm:

  • Phragmites australis – Common Reed
  • Schoenoplectus Tabernaemontana – Softstem Bulrush
  • Thypha angustifolia – Small Reed Mace

Substrate

The best substrate for planting pond plants is common gravel (3mm - up to 5 mm) or river sand. Such substrate is completely sufficient. There is no need to rinse the plants. After one day the water will be clear again.

Garden soil, peat, flowers ground, yellow sand cannot be used.

We often plant water plants in pots. This way we can keep plants' growth under control, remove the excess of them and replace them when and where we wish. We can use pots that are available in gardening stores especially designed for aquatic plants, or any other containers. A few holes in the bottom of the pot should be made. I can recommend pots in green, brown or black. White containers will look terrible. 

Sometimes our pond is completely or partly lined with stones and pots are not right. We can put the plants directly between stones, pressing them not to float. They will grow fine but not always where we wish.
