What plants effectively fight the spread of algae in the pond

When landscaping a pond in a garden plot, special attention should be paid to protecting it from algae. This will help plants that can prevent unwanted growth of uninvited guests. These representatives of the flora absorb harmful compounds and enrich the water with oxygen necessary for other inhabitants of the reservoir.

Submerged hornwort

The plant is native to South Africa and grows in lakes, ponds and slowly flowing rivers. There are compact varieties with short stems and stiff leaves. Hornwort is widespread in temperate regions.

It easily tolerates lower temperatures and winter cold. The plant is capable of withstanding immersion to a depth of 9 meters and has submerged leaves.

The hornwort has a long, rigid stem up to one meter long with branches in the upper part. There is no root system.

Hornwort is fixed at the bottom with the help of short processes - rhizoids. The plant floats freely on the surface and receives nutrients from the water. The leaves are small, resembling short needles, collected in small bunches. The color of the leaf plates can be light green, emerald, or reddish brown. Small flowers are almost invisible. Their pollination takes place in the water.

The main purpose of the plant is to aerate water and fight algae. Thickets of hornwort serve as a refuge for fry and small fish.

Common bog

Swamp, Krasovlaska or water asterisk grows in wetlands or reservoirs with stagnant water. The plant got its name due to the shape of a leaf rosette, reminiscent of a star. The stems of the plant reach a length of 40 cm and have a creeping shape. They are almost completely submerged in water or attached to a rocky bottom. Scaly outgrowths are formed at the tops of the shoots.

The shape of the leaves depends on where the bog grows. If the plant is partially on a soil surface, then the leaf plate is oval. Plants immersed in the aquatic environment have slightly elongated leaves with a shiny glossy surface.

Flowering begins in early summer. During this period, buds are formed in the leaf axils. They can be arranged in pairs or singly. The flowers of the bog are small, with pale green petals, which merge with the total mass of the leaves.

In household plots, the swamp is used to purify water in artificial reservoirs. At the same time, one should not forget that the plant grows rapidly and displaces other plantings.

Urut whorled

The large plant is a close relative of the hornwort with a creeping root system and well-developed lateral shoots. Most of the plant is usually underwater. And the tops of the stems, abundantly covered with leaves, rise above the surface.

Uruti leaves are thin, delicate and resemble lace.

Usually the surface of the leaf is brown. During the flowering period, flowers of a pale pink hue, collected in inflorescences-spikelets, rise above the surface of the water surface.

Urut is a valuable plant. It serves as food for the inhabitants of the reservoir. It is planted to protect the reservoir from rapidly growing algae.

Buttercup water

A floating plant that forms clusters on the surface of a reservoir. Buttercup has smooth stems that can be up to two meters long. With the onset of warmth, feathery leaves floating or submerged in water appear on the shoots, which outwardly resemble clover foliage.

In early June, the plant blooms with white flowers with teardrop-shaped petals, reaching a diameter of 1-2 cm. Flowers are located on long peduncles, towering against a green background above the surface of the reservoir.

After flowering, the leaves die off, and at the end of summer they reappear. Gradually expanding, buttercup forms a delicate openwork coating on the water surface.

Buttercup effectively purifies water in artificial ponds. It also has fungicidal properties that inhibit the development of pathogens and fungi.

A pond bloomed in the country: what to do?

Rest near a reservoir in the country is pleasant and useful, but for the water to be transparent, you will need to take care of it. One of the main problems is the appearance of an excessive amount of algae in the reservoir, as evidenced by the green color of the water. This problem is typical for small ponds where the water is very hot. The water can turn green immediately after filling the reservoir, but this phenomenon is temporary: after a couple of weeks, the biological balance will return to normal, and the algae will disappear. There is a concept of spring bloom, when the ecosystem of the reservoir is also restored after winter. The alarm should be beaten when this process continues for more than 2 weeks or signs of waterlogging appear in the summer.


Choosing plants for an artificial pond

Considering examples of small manicured ponds in landscape design, it seems that there is nothing easier than planting plants in a pond. But it is important to choose plants in such a way that they are in harmony with each other, forming a mini-ecosystem.

Some of them are planted around the circumference of the pond, and on the surface the wind drives the floating groups. Plants rooting in the aquatic soil take root at the bottom. Some of them are well known to aquarists and naturalists, for example, plants for a pond, photo:

Attention: The water in the pond can get dirty, ferment and turn green. It should not stagnate while receiving enough aeration to be oxygenated. A self-made reservoir needs water circulation, and pond plants need filtration and biological treatment of water. They cannot fully develop without light and organic feeding.

Plants available for landscaping a garden pond are conventionally divided into 3 groups:

  • floating
  • coastal
  • deep sea.

Aquatic plants are almost indistinguishable from those growing on land. Only some live in water and hold air in the leaves, producing oxygen with an abundance of light. Others draw water through the root system and produce oxygen in the same way when exposed to light.

With an excess of water, the roots begin to rot, but there is a type of plant that does not harm, they are conventionally called "swamp". Many people mistakenly refer to aquatic flora as "algae", but botanists only refer to primitive unicellular or filamentous organisms that way.


Why reeds are harmful

But before delving deeply into the methods of dealing with reeds, it will not be superfluous to find out what is really terrible about this representative of the flora. Reeds are most often found on moist soils that are located in close proximity to water bodies. Some gardeners independently "infect" the land plot with reeds, using it as mulch, as well as planting it between the rows of garden crops in order to supposedly fertilize the soil.

There is, of course, some truth in all this. The reed is capable of:

  • expel all weeds from the site, filling the territory
  • turn the top layer of the earth into humus.

In this case, you need to understand that, unknowingly, summer residents often confuse reeds with reeds, planting the latter to fight weeds and fertilize the soil. The land in which the reed grows quickly becomes swampy and turns into a piece of land unsuitable for growing garden and vegetable garden crops. In addition, it must be taken into account that the pond located on the territory of the site, with the dominance of reeds, very quickly crumbles, and then completely dries up. And you cannot save him from this fate.


How is the egg capsule useful?

The egg capsule has long established itself as a medicinal plant. It contains a glycosoid substance, on the basis of which drugs are created that help in the treatment of venereal and fungal diseases, as well as impotence. The capsule also helps with sciatica, rheumatism, gout.

Not many people know, but the water lily is also edible. Its fleshy rhizomes, fried or salted, can be used to prepare a variety of dishes.

If you are going to build a pond on the site, be sure to remember about the yellow pond when you select aquatic plants for it.
