What are marsh plants?
Swamp plants, as the name implies, are aquatic plants that love a swampy soil, which is the case at the pond bank. This type of plant likes to have wet roots. The rest of the plant, stems, leaves and flower, grows above the water. Bog plants are known for their ability to filter water well and thereby keep water values stable thanks to their strong root system. Marsh plants are therefore indispensable in every pond. Also, these plants are often a popular choice for plant filters or helophyte filters for the natural pond. There is a large selection of marsh plants, such as Irises and Lisdodde, but it is the most beautiful effect if you choose just a few species instead of everything mixed together.
What marsh plants are there?
Marsh plants come in all different shapes and sizes, there are marsh plants with large colorful flowers that attract many insects such as dragonflies and damselflies because of the nectar in these flowers. There are also marsh plants without flowers such as the Japanese cave pipe on Typha latifolia. Some of the most popular marsh plants are: Swan Flower (Butomus umbellatus), Pikeweed (Pontederia cordata) and Blue Lis (Iris Kaempferi).

How do you plant marsh plants in the pond?
Bog plants are pond plants that should be planted along the bank of the pond, this is because this is simply where they can best perform their function. How a marsh plant should be planted varies by species but most marsh plants may be planted to a depth of up to 40 centimeters. The plants can then grow well, marsh plants reach an average height of 100 centimeters, a real asset to the pond!
Why are marsh plants needed?
Marsh plants - or perhaps an entire marsh filter - are put in place if you want your water feature to look as natural as possible or because you think it's beautiful. After all, many marsh plants bloom with colorful flowers. But there is a much more important reason that marsh plants belong in a pond: they purify the water. Practically all marsh plants have strong roots and with them they extract many nutrients from the water. That makes this group of plants the perfect purifier to keep the water nice and clear. The nutrients that the plants use cannot go to algae and so they prevent algae growth from taking place. In addition, marsh plants help keep the water from getting too warm by blocking sunlight.
The right amount and depth
As with other pond plants, marsh plants need to be placed at the proper depth in the pond. The marsh zone is large in some ponds, and this is taken into account during construction. In fact, the marsh should not be deeper than -20 cm, otherwise the plants may rot or drown. We recommend placing the marsh plants in pond baskets in the pond, so it does not immediately become a mess of plants that make roots everywhere. How many marsh plants do you place per square foot? Simon recommends placing at least 1 basket (with 4 plants) and up to 4 baskets (total of 16 plants) per 1 square meter for best results.
What plants in a swamp filter?
If you want a functioning marsh filter, it is important to plant it correctly. You do this with a combination of high and low marsh plants with oxygen plants in between that cover the surface of the marsh. This is because in this way the sun does not have free rein and the plants keep the water temperature low. One of the best marsh plants that filters water is the lis (Iris). This plant has an excellent root system and reduces nitrite and nitrate in the water. Irises are also good marsh plants and it is Simon's favorite because they are primal and hardy.

Hardy marsh plants
Naturally, your pond is in the garden year-round. Then it is nice if the pond plants also stay alive all year round. Therefore, you can rest assured that all our marsh plants and other aquatic plants are hardy. If they are planted correctly and pruned on time, you have hardly any other worries about your marsh plants. We would like to highlight two special species that can enrich your pond. For example, dwarf licorice (small miniature licorice) is an iconic sight in any pond and water mint is highly recommended because you can make tea from its leaves.

Marsh plants for a swimming pond
Want a swimming pond in the garden? Good idea. In a swimming pond, two different pond plants are usually placed, oxygen plants and marsh plants. Oxygen plants are usually placed in the deep part of the pond and among the marsh plants. Especially for a balanced marsh filter, Simon has put together a marsh filter package. Convenient of course if you can immediately purchase these plant species in the right composition.

Marsh plant the carnivorous plant
Carnivorous plants are a valuable addition to any pond with their brilliant colors and whimsical shapes. These hardy marsh plants thrive best in nutrient-poor soil. The less nutrients there are in the soil, the better these plants grow! Therefore it is important to separate these plants from other pond plants that do require nutrition. If you are bothered by insects around the pond, the carnivorous plant is the ideal solution, as the plant catches the insects and feeds on them.
