He is winterized. Last plant work is done and not hardy plants and animals must be wintered out and frost-free. So there is still a lot to do before the first frosts freeze life...
Take the pond pump and electronics out of the pond
Pumps, fountains, hoses, all these things that are not frost-resistant can be damaged in the pond in winter. Water expands when it freezes and hoses burst, pumps can not withstand the pressure. Alternatively, pumps and filters can continue to run during the winter. This also prevents the units from freezing. Neither the ventilation fan nor the filter pump may be placed on the bottom of the pond to prevent turbulence of the water in the depth. It is better to place them on a 20 to 30 cm high stone. It is important to leave only pumps in the pond, which frost can not harm.
- Do not remove hardy equipment and keep it free from frost
- When buying pumps, etc., pay attention to winter hardiness
Throughout the fall, foliage and bushes have to be harvested, regularly. If you do not, it sinks to the bottom of the pond and becomes sludge. There are fermentation gases. The foliage changes the overall water quality and releases lots of nutrients that often lead to algae plague next year. Depending on the amount of leaves should be fished daily. If that is too much work for you, you can alternatively attach a leaf protection net over the pond. This keeps at least the middle and larger leaves. Nevertheless, the smaller leaves that hatch through the mesh should be regularly collected.
- Depending on the amount of foliage daily fish
- Foliage nets offer alternative
In autumn, the beauty of pond plants usually decreases rapidly. The leaves turn brown and unsightly. In the middle of October, but also in November (depending on the weather) they are cut back. To densely proliferating plant populations are lighted. Too abundantly growing plants can be regrouped or removed. It is also important to remove dead parts of plants because they can also form fouling gases. Besides, the fragrant is cut off. Now is also time to harvest the seeds of the aquatic plants. In addition, it is recommended to stew the deep zone. Reeds, reeds, cattails and all plant stems that are strong and hollow inside are not cut. They look great with hoarfrost and also keep the water surface a bit open in frosty weather.
- Cut off brown leaves and stems
- Cut back or cut out plants
- Remove dead plant parts
Tropical aquatic plants and all non-hardy plants are better wintered outside the pond in a frost-free place. Recommended are shallow bowls that are placed on a sunny window sill. Alternatively, not quite as sensitive plants can be implemented. Some water lily species or varieties are simply placed at the deepest point in the pond. The depth must be at least 50 cm, but even deeper is better. There they can stay until April.
- Hibernate tropical aquatic plants in the house
- Some water lily species are not hardy
- In some plants, the conversion reaches deeper zones, at least 50 cm deep
If the garden pond is optimally laid out, that is, big enough and at least one meter deep, you can leave fish to yourself and do not have to worry about them anymore. They can stay in their usual environment. As in nature, well-fed, healthy animals survive the winter. A natural selection always takes place, but that's normal. At lower water depths, it becomes dangerous for the fish, depending on the severity of the winter. In mini ponds and shallow pools fish can not survive, as well as in pots, tubs and other vessels. They should be fished out for the winter. It is ideal to place them in a frost-free room in which the temperatures settle between 5 and 8° C. Well suited is an aquarium, but other vessels do too. The size depends on the number of fish. As a rule of thumb, 10 cm of fish should contain 10 to 15 liters of water. It is recommended to cover the vessel with a grid or a coarse-meshed fabric stretched over it, because the fish also like to jump and fly over the edge. Ground can be left out, even light is not necessary.The fish also need no plants or any decoration. At water temperatures below 8° C fish need no food. It is favorable, however, if the vessel is ventilated with a ventilation pump via a discharge stone. If the cold wintering is not possible and the temperatures rise above 8° C, the fish must be fed. As a result, the filtering of the water is necessary, the feces and food residues pollute the water. Every two to three weeks, about 1/3 of the water should be changed. It is also useful to add a water treatment agent. For fish remaining in the pond, it must be ensured that the water surface does not completely freeze. This can be achieved in different ways.
- Fish survive only in large and deep ponds, at least 1m deep
- Threaten to freeze, fish better and spend the winter in the house
- Large vessel, depending on the number of fish
- Cover vessel with grid
- Connect the diffuser pump with discharge block
- Water temperature between 5 and 8° C
- Regular water exchange
- Do not feed fish below 8° C
If the pond is big and deep enough, local fish can safely spend the winter outside. As described above, they are only fed as long as the temperatures require. It is important to keep the pond, at least one place ice-free, so that oxygen enters the pond and digester gases can escape from the water. There are different ways to achieve that. Large, strong water grasses ensure that the ice between them has open spaces. In heavy frost but there should be controlled. In addition, the pond can be covered with a correspondingly large Styrofoam plate. This must be provided with ventilation holes. The plate is placed on the pond. The movement of the plate on the water prevents these holes from freezing. Through them oxygen enters the water and the fermentation gases can escape. Of course, this variant is only suitable for smaller ponds.
Another method is to cover the water surface with PE balls. The air-filled balls prevent too much cooling and freezing of the water. The balls are translucent, so that there are no disadvantages to be feared for the living things in the pond. At least two-thirds of the pond should be covered with the balls. Black balls are often recommended. Although they heat up the fastest and give off the heat to the pond water, but they also let the least light through. In addition, they look very dark and rather strange in the winter garden. Better are green balls. They match color, let more light through and heat up quite well. The air in them heats up quite quickly, which can be beneficial for the cooling of the pond. PE balls are not a cheap choice. They are harmless for that. The plastic contains no plasticizers, so no toxic substances are released into the pond water. There are even those that have been tested for food authenticity.
In many ponds oxygen stones are used. Depending on the size of the pond, more or less of it will be needed. If they are placed in the right place, not too high and not too deep, they make sure that one or more places remain open in the ice. They create oxygen bubbles, through which the water in their environment remains in motion and no ice can form there. Glad to be used Eisfreihalter. There are several types of it to buy commercially, with and without electricity. But you can also make one yourself, that's not difficult. In the case of polystyrene rings, an anchorage must be ensured so that the light part is not blown away by the wind.
- Big, strong water grasses
- Cover with Styrofoam plates
- oxygen stones
- ice preventers
From the end of September it will be quieter in and around the garden pond. Plants and animals prepare for the winter. To make their survival easier, a lot can be done. If you take care of your pond regularly, you will not have much to do in the fall. Devices are, if they are not suitable for winter operation, taken out of the water, maintained and stored, the plants are cut, sorted and / or implemented, foliage must be fished out of the water, possibly even from the depths to be fetched. Growths and creatures that are not adapted to our climate are wintered better in the house, but not at living room temperatures, but at 5 to 8° C. It is important to ensure that an inhabited pond does not freeze, unless it has the appropriate size and depth.
