Awl-shaped bryozoans: features and secrets of growing Irish moss


Species of bryozoans (Sagina subulata), mountain species from the genus Msanka (Sagina) - creeping perennial, summer-green and winter-green groundcover flower plant. It grows in the composition of the flora of cold and moderately warm regions of the Northern Hemisphere. Used in culture since 1881.

Awl-shaped bryozoans: description, decorative forms and varieties

The bryozoan of the styloid is sometimes called the bryozoan of the styloid or Sagina. A pillow-shaped growth is characteristic - a stalk strongly branching near the soil itself gives a lot of shoots. The leaves are bright green, small, turning at the tip to the tip up to 1 mm in length. Flowers with five white petals, up to 5 mm in length, bisexual. Growing, it takes the form of a loose pillow. Inside the pillow, its own microclimate forms. - the shoots are protected from the adverse effects of winds and are well warmed by sunlight. It is steady against adverse climatic conditions. Prevents weed growth. It grows slowly. Used in landscaping to create floral arrangements.

In relation to light - heliophyte (photophilous plant). It tolerates a lack of moisture - xerophyte. It blooms from June to August. Stably decorative all year round.

Decorative forms:

  • Sagina subulata var. subulata - sepals pubescent with glandular hairs;
  • Sagina subulata var. glabrata - sepals bare;
  • Aurea - yellowish leaves.

On sale you can find a variety of bryozoans "Surprise", which is characterized by an adult plant height of up to 8 cm, abundant flowering with white flowers. Crispy variety has a variety of bryozoans blooming with yellow flowers.

The cultivation of bryozoans

Awl-shaped bryozoans: landing and care

The bryozoans is subulate, growing over 2 years, and covering large areas with a continuous carpet, allows moisture to be kept at an optimal level in open sunny gardens.

Soil and planting material requirements

Requires well-drained neutral, or slightly acidic soils. Before planting, the soil is moistened. The most favorable soil is naturally moistened by precipitation.

The substrate with the optimal composition:

  • coarse sand - 2/3;
  • sheet land or peat - 1/3.

A mixture of heavy loam with peat 1: 1 is also suitable for growing. Clay can be added to sandy loam soil by applying it with a layer of up to 10 cm superficially, without digging.

In flower shops you can buy bryozoan seeds with white or yellow flowers, as well as ready-made seedling material.

Cultivation of bryozoans of the awl-shaped seed

In March, seeds are sown randomly in low trays with nutrient soil from a mixture of turf and leafy soil. The surface layer is passed through a sieve. Before sowing, the soil is moistened and slightly compacted and leveled with a smooth, put on a rib plank. Ground sprinkling is not required. The trays are covered with plastic wrap and placed in a warm place with t 25º C. After germination, the seedlings are dived into larger containers. Planted in a permanent place at the beginning of May, observing a distance between seedlings of 5-10 cm. Bryozoans breed well in the future by self-sowing - from ripened capsules the seeds fall into the ground and germinate. Seeds can also be planted directly in the ground.

Despite the fact that the bryozoan is considered an unpretentious plant, it requires careful observance of all agricultural practices during propagation and cultivation.

Basic care rules

Regular watering is required. Do not allow the soil to dry out between irrigation. He loves partial shade, but tolerates well-lit areas.

For normal growth, fertilizing is carried out:

  • ammonium sulfate, especially necessary in the first year of life, is introduced in early spring and in the first half of July - 45 g / m²;
  • superphosphate, which promotes growth and resistance to drought, is fed three times - in the spring, summer and autumn 16 g / m²;
  • potassium, due to which shoots grow well, and the plant forms resistance to frost, is applied three times per 10 g / m².

The carpet from the bryozoans does not tolerate strong trampling, so the boulders scattered around the lawn perform not only a decorative function. They can be relied upon during weeding.

Disease prevention

The bryozoan may die with excessive moisture or freeze in a snowless winter.

Noncommunicable diseases are caused by adverse external conditions:

  1. With a sharp drop in temperature in the fall, the bryozoan does not have time to adapt to the cold and freezes. Phosphate fertilizers introduced to frost help tolerate frosts.
  2. Warming occurs when snow falls on moist and still warm soil. The plant does not fall asleep, but continues to develop in conditions of lack of light and nutrients. More often occurs with excessive nitrogen nutrition, in moist clay areas.

With excessive soil acidity, excessive application of phosphorus, frequent irrigation, the plant lacks iron, which manifests itself in the form of chlorosis - a pale yellow color. If such changes occur, make complex fertilizers.

A bryozoan can harm aphids, which they get rid of with the help of insecticides.

How the bryozoans propagate

Plant propagation technology

The most effective method of propagation is by dividing the bush. It provides a high survival rate. In spring or early fall, adult plants are separated. Each part should have intact stems, shoots and roots, which in the bryozoans are superficial, densely braiding the upper layer of soil.

Planted in soil, freed from weeds and moistened. Pieces of plants are planted either next to each other or at a certain distance, depending on the amount of planting material. Bryozoan quickly takes root, grows and forms a solid green carpet. 15-30 plants are enough for 1 m².

Sod can be cut with a shovel into pieces and planted.

Irish moss lawn and other garden design uses

Bryozoans or Irish moss is used to create an grassless lawn. Large gaps are filled between the tiles scattered in the artistic mess on the track. Framing the paths, used for landscaping rocky areas, alpine slides or areas with a small nutrient layer.

  • Even in a small area, using natural motifs - soil, stone, stream or a small artificial decorative reservoir, you can create a picturesque corner. The banks of the reservoir are made out of natural stone, in the gaps of which is located a bright green, creeping bryozoans.
  • The bryozoan is able to overcome a small boulder, hiding it completely under its cover.
  • The bryozochny carpet is beautifully combined with coniferous trees and bushes - juniper, arborvitae, fir, boxwood. In a multi-tiered composition, plants of various heights look advantageous.
  • Like imitation moss, it can be used to create Japanese-style compositions. Bryozoans can be planted separately, it harmoniously fits into any style, both landscape and regular.
  • If the plot is small in size, you can limit yourself to a bryozoan and several boulders - create a concise composition. Indispensable for creating mountain landscape installations and on terraces of rocky gardens.
  • The bryozoan looks favorably next to succulent plants. Planted on a flower bed with bulbous plants, it acts as a mulch - it protects the bulbs from moisture loss and prevents the growth of weeds.

Cultivation of the styloid bryozoan at home

Bryozoans usually sow places difficult to access for care. The site is freed from weeds and a planted plant. Throughout the season, grass and weeds must be weeded out between the plants.

At sites where water stagnates, you can build a drainage:

  • remove the soil layer;
  • distribute drainage material (gravel, broken brick) with an even layer of up to 15 cm and carefully tamp;
  • place a layer of sand up to 10 cm high on top, seal;
  • lay fertile soil on top and tamp with a skating rink (as a skating rink you can use a barrel of water, 100 l in volume).

At home, bryozoans are grown from seeds. Best seeds germinate in the light. Then the seedlings are dived and in May planted in a permanent place. After planting in the soil, seedlings must be watered daily for two weeks - it's important to keep the soil moist, but do not allow waterlogging. From sunburn seedlings can be protected with a white spunbond. Processing with EPIN will allow seedlings to take root faster. To prevent freezing, they mulch fallen leaves for the winter.

The advantage of a grassless bryozo lawn is that it does not need to be mowed - a height of 5-8 cm is constantly maintained. The bryozoan, growing, does not allow weeds to take possession of its territory.

The surface of a bryozoan carpet is never uniform. Bizarrely hilly, shimmers with green halftones and shades, resembles a velvet tablecloth. Using the capabilities of this seemingly nondescript plant, you can create fantasy mini-kindergartens in any and even inaccessible corner of the garden.
