Garden pond owners should use autumn to make their pond winter-proof and frost-proof. What happens to plants and animals in the pond in the freezing frost? Nature has taken precautions, but we can help to ensure that nothing freezes and breaks. Your pond will get through the winter well.

The more natural a pond is, the less you have to worry that severe frost could damage it. Nature has its laws and responds accordingly: Natural waters are usually 60 centimeters or deeper.

Ponds, ponds and pools with a lower water level are not winter-proof in the long run. At some point they freeze to the bottom, and some living things and frost-sensitive plants no longer have a chance to escape the ice. We must therefore pay particular attention to ponds that are not deep enough or to those that are populated with fish. Concrete or brick pond pools of all kinds are also at great risk. Because the ice that forms could damage or even blow up the pool rim due to its enormous pressure (the volume increases). Vertical walls are more at risk, sloping less.

Tips to absorb the pressure of the ice in the pond

  • The safest way to protect a brick pond from freezing is the most tedious: the water is drained off.
  • If it is too late to do this because a layer of ice already prevents it, holes can be melted in the ice (garden burner) and a few buckets of water can be skimmed off. An air cushion then forms between the ice and the water basin, which prevents further cooling. However, only if the hole is covered again, for example with a straw mat or with a hard foam plate (place weight on it so that the wind does not blow the plate away).

Protect frost-endangered garden pond plants

It is best to put exotic aquatic plants in baskets so that they can be carried to a frost-free place for the winter. Lotus flower, water hyacinth, papyrus, cypress grass and calla cannot do without this winter protection. Bring the containers to the basement, the greenhouse or the winter garden. With the right humidity, some plants can also spend the winter indoors. On the other hand, native plants such as water sword lilies and frog spoons - including water lilies - can safely overwinter in the pond if the root ball does not freeze through.

Tip: The storage location must be bright enough and the temperatures must not be below 10 degrees Celsius. Water hyacinths or mussel flowers even require 15 to 18 degrees Celsius.

Water lilies can safely overwinter in the garden pond, provided they are native and not exotic varieties.

Remove autumn leaves from the garden pond

In general, autumn leaves are not a problem for the pond as long as it is not stirred up. Keep the pond free from falling leaves of surrounding trees and shrubs by stretching a plastic net. It is best to remove any blown leaves or sections of grass or anything that has died in the pond water immediately. Leaves in the water decompose, consume oxygen and release toxic fermentation gases which can be fatal to fish and other living things under the ice cover. Never punch a hole in the ice!

Tip: Be careful when cleaning. Aquatic plants overwinter in the form of small buds on the bottom of the pond, and they are protected from frost in the mud at the bottom of the pond.

Maintain water and bank shrubs

October and November are good months for pond maintenance and for small transplantations. The multiplication of water and bank perennials by division is also possible. You can cut back trees on the bank. You should leave reeds, cattails and other dead plants calmly until spring, because insects overwinter in the plants. Tying up long grasses at the top prevents frostbite.

Protect water pump from frost

Water pumps should be removed from the garden pond and kept in a bucket of water before winter so that they do not freeze in frost. Filters and other technical systems for water treatment should also be dismantled and protected from frost so that they do not break.

Fish need oxygen

Don't worry that the goldfish will freeze to frost. Winter time means a rest for fish in the pond. Circulation and metabolism are greatly reduced, so that there is no need to be fed; the natural food in the pond is sufficient. You don't have to get the pond ice-free. An ice sheet does no harm to the fish, they can flee to the bottom of the pool and stay there, provided the pond is sufficiently deep (at least one meter). However, gas exchange must be ensured, fish need oxygen - and they often do not get it enough under the closed ice cover. But if you now helpfully punch a hole in the ceiling with the pimple, you should know that the mighty roar causes the animals to panic, and that under extreme ice conditions, the fish's swimming bladder can jump under the ice. Better: If there is a risk of frost, put a piece of wood in the water and let it freeze. See diagram:

Once the layer of ice has grown to 3 to 5 centimeters, carefully break out an opening around the wood. Then scoop water out of the pond with a bucket and lower the water level by 10 centimeters. The layer of air between the ice sheet and water functions as an insulation layer in frost. To prevent a second layer of ice from forming, cover the air hole with a mat or board.

Insulate the garden pond winter-proof

A layer of snow insulates and protects plants and animals from the cold. The trade offers so-called ice-free holders, which are best positioned above the deepest point in the pond. In the event of severe frost, you can also use a pond heater that does not freeze the water under the top layer of ice in winter.
