Plants give visual interest to a pond, encourage wildlife and can help keep water clear. Choosing the right plants greatly adds to your enjoyment of the pond as well as that of visiting or resident wildlife.
Planting a pond:
Plant marginals with 3 – 15cms of water over the soil surface in groups of 3 – 5 of the same variety.
Small pots should be secured to prevent fish disturbance.
Approximately 30 – 40% of the pond surface area should be covered to provide shade for fish and reduce algae growth.
Short growing oxygenators can be placed on marginal shelves. Deep water varieties are best planted, but can be left loose in the bottom of the pond.
Simply place floating plants on the pond surface.
Plants in solid pots should be transplanted into mesh pots to allow water and oxygen to freely circulate the roots.
Lay out your planting as you would a flower arrangement with tall plants at the back and low plants at the front.
Approximate planting density for pools:
Water Lilies: 1 per 2 – 3m sq.
Marginals: 5 x 1 litre or 3 x 3 litre plants per m.
Oxygenators: 2 – 3 bunches per m sq.
Floating plants: 2 – 3 plants per m sq.
A beautiful addition to any pond.
The leaves shade the water, providing shelter for fish, helping to keep it clear and reduce algae.
Lilies like still water. Do not place near fountains or where water can splash on the leaves.
Depth: The depth for specific varieties is on the reverse of each label. Even miniature lilies are best planted with the crown 10cm below the water surface to protect from frost. Large lilies can go to a maximum recommended depth of 1.2m. If leaves rise up above the surface, remove the old leaves on the surface, allowing space for new leaves to lie down onto the water.
Check the back of the label for variety-specific details.
Oxygenators photosynthesise underwater creating oxygen which then dissolves. This is not only essential for all animal life, but also for bacteria which helps keep the water clear. All bunched oxygenators benefit from their roots being pushed into soil except for Ceratophyllum.
Many oxygenating plants have two forms of foliage; submerse (below water) and emerse (above the water) and they can look very different. It is only foliage below the water that oxygenates the pond.
Container grown oxygenators have plant information on the reverse of the labels.
