Waterlilies Winter - Care of pond plants in winter: winter

In many gardens, the garden pond is an important design element, but its effect only unfolds through the correct planting. A variety of water and marsh plants are available in the trade, but not all of which survive the cold season without damage. Whether water lilies and other plants are really hardy depends not only on their origin, but also on the depth of the water.

The deeper the garden pond, the easier the hibernation

A naturally designed garden pond consists of three different zones, which are populated with different types of pond plants and also treated differently during the winter months. Basically, the rule applies: The deeper the garden pond or a certain area, the easier it is to hibernate. Waters that are more than 160 centimeters deep seldom or never freeze to the bottom; instead, even at outside temperatures of more than minus ten degrees Celsius, plus degrees prevail. For this reason, fish, but also many floating plants overwinter here more easily. On the other hand, depending on the species and variety, plants from the marsh or shallow water zone must be specially protected during the winter months.
Tip: Some plants of the shallow water zone, such as native water lily species, can be brought into the deep water zone before the onset of winter and survive the cold season there more easily than in shallow water. For this purpose, it is convenient not to plant the plants directly into the pond bottom, but instead in grid baskets. In the fall, they can be easily lifted out and put into action.

So hibernate aquatic plants from mini ponds

Conversely, of course, the lower the water level, the more dangerous it is for the aquatic plants. Mini-garden ponds, which are sometimes set up and planted in pots and planters such as a zinc tub, freeze to the ground in frost very quickly. As a result, even those aquatic plants that are accustomed to frost as native species die off. However, it is problematic if the rhizomes of the water lilies also freeze and can no longer provide the plant with moisture and nutrients. Therefore, for miniature oak: Winterize it always frost-free, but cool at temperatures of less than ten degrees Celsius. If the vessel is too big and / or too heavy, you can also drain the water down to a few centimeters or overwinter the plants together with the basket individually in buckets or larger planters.
Tip: When hibernating in the house or in the greenhouse, you should always keep in mind that the darker it is, the cooler the ambient temperature must be. If the plants are over-wintering, their metabolism is stimulated and they quickly suffer from lack of light. In a rather dark hibernation, the temperature should be just above zero.

Not all water lilies are hardy

Worldwide there are about 50 different types of water lilies, many of which are native to our latitudes. Others come from the tropics and would not survive a cold winter outside in the garden pond. Locals and thus winter-hardy water lilies overwinter best as follows:
  • Lowering to a water depth of at least 60 centimeters deep
  • some species even at a depth of up to one and a half meters
  • Removing dead and rotten plant parts in autumn
If a hardy water lily lives in a very small pond that is less than 60 centimeters deep, you should either transfer it to a deeper pond or overwinter it in the house in a frost-free and cool place. Even with hardy species, the rhizomes must not freeze, otherwise the water lily does not drive so well in the following year.
Tip: When buying winter-hard water lilies, pay attention to their origin: Some native species are imported from aquatic plant schools in Asia, where of course they can not be cured accordingly - and do not train the desired winter hardiness despite their predisposition.

Winter-hardy pond plants spend the winter

Many other typical pond plants are at home with us and have developed their own individual tactics for hibernation. Some - for example pipe - are from the outset extremely frost-resistant and need no special cut, they should only be cut back in the spring before budding. Others, however, such as crab claws, sink in late autumn, on the other hand, on the pond bottom, overwinter there and emerge in the spring of its own again. However, for these species to survive the winter, the pond should be deeper than 60 centimeters. Many pond plants produce so-called winter buds in the autumn, from which they finally drive out in the spring.For this reason, these species, which include, for example, the water plague, must not be cut back from August - with a late pruning you would remove the winter buds and thus prevent them from sprouting again.

Prepare garden pond for the winter

So that your hardy pond plants survive the cold season as well as possible, you should winterize not only the plants, but also the whole garden pond in autumn. This includes the following works:
  • Run the water pump empty and winter free from frost
  • remove all foliage from the water surface
  • remove diseased and foul plant parts with a pond scissors
  • also remove these from the pond
  • to make up dense crops
  • Roughen reed
  • Remove digested sludge with pond sludge sucker or bucket
  • if necessary, use ice protectors
Tip: Digested sludge forms from the dead plant parts that have been lowered to the bottom of the pond. It releases poisonous hydrogen sulphide gas which, especially under an ice cover, can be dangerous to fish and plants. Digested sludge, however, gives a very good fertilizer, can also be spent on the compost.

Keep sensitive pond plants properly in winter

Non-hardy, tropical pond plants are relocated to the house before the first frost. They winter as well as hardy water lilies, frost-free, but cool at a maximum of 10° C. These species may only be released into the open air after the icy saints in May, but then they must first slowly become accustomed to the sun again. In addition, many plants from the marsh zone are only partially winter hardy. They can stay outside, but should be moved to deeper water. Here they survive even temperatures of minus 10 degrees Celsius and more easily.
Tip: In the house or greenhouse wintered pond plants must be checked regularly. If necessary, you should check the water level, because the plants must not dry out under any circumstances. A winter in the dark cellar is not recommended.
