Many hobby gardeners deliberately choose to add a garden pond to their garden Include garden design. He beautifies the garden and is often used as a retreat. Of course, decorative plants should not be missing in the pond. Most pond plants do not require much care, but even keep the water clean and prevent algae growth. The selection of pond plants is large. The individual species differ not only in appearance, but especially in their winter strength and hardiness. Whether or not a pond plant is hardy or not depends primarily on the location of the plant.

The garden pond is divided into several zones according to its depth and there are plants that are especially suitable for each pond area. Floating plants are distinguished from the marsh plants for the marginal area and the deep-water plants. All these pond species have different things to consider when it comes to hibernation. When buying the pond plants, you should therefore think of the winter, so you later have no problems when it comes to the wintering of the plants. In this guide of Heimhelden we have put together many useful tips for you, so you can still enjoy your pond plants after the cold season.

Which pond plants are hardy?

Before you buy plants for your pond in the garden, Be sure to read up on how to get the pond plants through the winter. There are many robust floating plants that can cope well with frost and that you do not need to care for even in the cold season. In particular, deep-water plants can often simply overwinter in the garden pond. These include, for example, native species such as:

  • Water Lily
  • Lotus Plants

This is less due to the characteristics of the plants, but rather because the temperatures are highest in the deep water of the garden pond. For this reason, it is also appropriate to implement less frost-resistant plants before the onset of winter in the deep water area, so they can stay outdoors. In addition, reeds and pond grasses are very hardy. They are usually planted in the swamp area of ​​the pond and can usually remain there without problems. It only becomes dangerous for these plants if the temperatures remain in the double-digit minus range for a long time.

How are sensitive plants overwintered?

There are unfortunately many plants in the marsh zone that are not really hardy. In the swamp zone it is the coldest in winter, while in the deep-water zone the temperature increases the lower you go. Accordingly, a plant that has its roots in the deep soil of the pond has a better chance of surviving the winter unscathed than a delicate plant in the shallow wetland on the bank of the pond.

Sensitive plants from the pond's swamp area should, if possible - Best implemented in the deeper area. Swamp plants, which are only partially hardy, survive in this way.

Grasses and reeds in the wetlands can easily withstand temperatures of up to minus ten degrees Celsius. However, as soon as the temperatures drop even lower, frost damage is possible. You are on the safe side, therefore, if you implement the plants before the onset of winter in the early autumn. In addition to the wintering of the pond plants include other measures: they should be well cut back and wrapped with a jute bag or with a water-permeable film. So they are better protected from the frosty temperatures.

Is it possible to hibernate aquatic plants in the cellar?

There are some special species of pond plants that do not tolerate cold temperatures at all. This is especially true for all tropical plants. In this case, it is also not sufficient to implement the plants in the deep water zone. Instead, you should bring the pond plants to a suitable place in the house in the autumn to hibernate them there.

Even classical pond plants such as water lilies or swamp lilies are not winter proof, as long as the pond has a depth of less than one meter. Therefore, all plants should be rearranged before the winter, if it is a shallow pond.

For hibernation, the following procedure is recommended:

  1. First let the water out of the pond.
  2. Put the Carefully transplant the plants into suitable containers.
  3. Bring the pond plants into suitable quarters such as the cellar.

It is ideal if you have placed the plants in a basket in the pond right from the start. Then the removal of the plants from the garden pond is much easier than if they were planted directly in the ground.

If you want to overwinter the pond plants in the cellar, you should take the opportunity to examine your plants more closely. Cut off dead leaves and roots, because if the plants are affected by a disease, they prevent the disease from spreading and killing the entire plant. In addition, replace the plant substrate so that the pond plants receive new nutrients. In the specialized trade you will find for this purpose special granules or Teicherde. Under no circumstances should normal potting soil be used because it contains too many nutrients and would promote algae growth. So that the potting soil does not trickle out of the planting basket, you can lay it out with fleece. Afterwards, fill the containers with water and bring them to the place you have selected for wintering.

A winter room is a room that can last for a maximum of twelve degrees Celsius. Nevertheless, the pond plants should receive enough daylight. They would not be able to stand in the dark all winter time. Do not forget your pond plants even in the cold season, but check the water level at regular intervals. Under no circumstances should the aquatic plants dry out, as they would quickly die.

When may the pond plants be put back in the pond?

If you let your pond plants in the cellar over the winter, you can return the plants to the pond in May Reset the garden. It is best to orient yourself on the ice saints, because as long as they are not over, it can get very cold again at night. As soon as the last night frosts are over, simply put the plant baskets back to the desired location in the garden pond and fill up the pond with water.

Conclusion: A sufficiently deep garden pond is also comparatively easy to care for in winter

For a small water oasis is probably in every garden space. Even an old wine barrel or a zinc tub is suitable to create a mini pond. If you then install a pump and a small fountain, you have created a great eye-catcher in your garden. Only the plants in the pond must be wintered in winter in a suitable quarter, otherwise they freeze. With larger ponds, however, it is no problem for most plants to let them hibernate in the pond, as long as they are indigenous and robust plants and the pond is sufficiently deep.
