Acute sedge is one of the most common types of perennial herbs. What is this plant especially about?
Sedge acute: description
In appearance, this plant resembles cereals quite strongly. Its stem has a cross section in the form of triangles, and leaves are attached to the lower part. As a rule, they grow flat and reach from 2 to 6 mm in width, and are equal in length to the main part of the plant. In most sedges, the leaves have a bright green color, sometimes grayish can occur.
By the way, if you gently slide your fingers over the plant, you can cut yourself deep enough. This is because there are stiff spikes on the foliage of the grass, although they are not visible due to their tiny size. But they are easy to feel - plants of the sedge family have a noticeably rough surface. Their full height reaches from 50 to 150 cm. The habitat of acute sedge is sandy, as well as silty shores of water bodies. It is widespread in Central Asia and Europe.
Ears of plants
The sedge blooms in a peculiar way - decorative processes bloom on it. These are inflorescences that have long cylindrical spikelets. They usually hang on long legs. Inflorescences are a separate part of a plant that performs the function of pollination. Often it is modified and therefore looks more attractive than the stem and leaves.
Acute sedge has in its inflorescence from 1 to 4 stamens and from 2 to 5 pistil ears. The latter can reach 7 centimeters in length. Spikelets of sedge are sessile, their scales, which completely covers the surface of the process, have a brown or dark brown color. They are protected from the outside world by special covering leaves. In their length, they are approximately equal to the inflorescence or even exceed its size.
Plant root system
In sedge acute, the underground part is unusually well developed. The smallest length of the rhizome is 1 cm, the largest reaches 25 cm. It is distinguished by yellowish shades and a felt surface.
The plant has diatropic shoots. By the way, the acute sedge root system sometimes grows so much that noticeable soil mounds form around it.
Plant properties
Due to the high amount of silica contained in the leaves, they have a cutting surface. Another unusual property of sedge is acute - it grows very well in water or marshy areas, despite the fact that the structure of this grass vagina is found only on the bearing parts of the plant.
Environmental group
What it is? This is a collection of plants that have similar properties and anatomical and morphological needs from the outside world. So, what are the acute sedge ecological groups? Regarding the humidity of the medium, organisms are divided into hydrophytes, hygrophytes, mesophytes, xerophytes and cryophytes. Osoka is a representative of the second group from this list. Hygrophytes are plants that are common in areas of high humidity.
Relative to light, plants are distributed into heliophytes and sciophytes. But acute sedge is not specifically attributed to any of the groups, since this grass is indifferent to lighting - it feels equally good both in the bright sun and in the shade.
In relation to temperature, wildlife is divided into megatermophytes, mesothermophytes, microthermophytes and geckistothermophytes. Acrid sedge is a thermophilic plant. It belongs to mesothermophytes and prefers a temperature of about 20 ° C above zero.
Plant care
Many gardening and gardening enthusiasts are interested in sharp sedge. This is one of the types of perennial herbs that are not particularly picky in care. This plant attracts the attention of gardeners. It belongs to meadow and swamp species, as it is not afraid of either excessive humidity or direct sunlight. Sedge prefers high air temperature, so it is better to transplant it in warm time, in clear weather.
The plant likes rather moist soil, therefore it is recommended to water it more often. It is really important to pour sedge abundantly and regularly with water. By the way, the first planting of the plant must be done at a temperature of 18 to 30 ° C and in a fairly bright sun. This ensures that the sedge will take root and grow well.
When caring for this plant, not only watering is important, but also mowing. This process provides a decent look for your garden and good sedge growth. Another important point in the care of the plant is its spring cleaning. It includes cleaning sedge from dry leaves and various natural wastes. Even the most experienced gardeners can easily do this, since there is nothing complicated in the cleaning process.
Despite the fact that there are no special difficulties in caring for sedge, all the rules must be strictly observed. Otherwise, the root system will slowly rot in the plant, and the edges of bright green leaves will turn black. If you notice such problems with sedge, you should urgently review the correct care for it.
Possible difficulties
Normalized irrigation and a fairly high air temperature can become the optimal care for sedge. But if the plant is in the stage of active growth, it can become quite demanding for a while. It would seem, how can sedge be so picky about the outside world? During the period of active growth, the plant increases sensitivity to abiotic factors. At this time, sedge can “catch” a variety of noncommunicable diseases.
These are sedge damage that occurs due to regular errors in care and inattention to external factors, such as improper lighting, humidity, temperature, watering, and plant location. Sometimes it can even be affected by the quality of the container or substrate. To prevent all these difficulties in the development of sedge, it is recommended that you familiarize yourself with all possible difficulties in advance.
Dry or waterlogged soil? And in fact, and in another case, the plant wilts, its leaves fade. With continued improper care, it will simply die. Therefore, it is important to monitor normal soil moisture. If the plant turns yellow leaves, it means that there is a lot of water for it, and if it turns black - on the contrary, too little.
Optimum irrigation for sedge - such that the soil is slightly wetter than other plants, since the grass is very sensitive to dry soil. And if you grow it in a home flower pot, then in no case do not allow swampy soil.
Low air temperature? As was written above, sedge is a heat-loving plant, so keeping it in places with low temperature is a big mistake. And if during the day the plant is warm and comfortable, then such sharp changes will adversely affect its health. It is necessary to ensure that the grass is always located in sufficiently heated areas. If you grow sedge in a home pot, then move it away from the windows at night.
