Creating a decorative, long-term, resistant to adverse conditions lawn, you must start with the right choice of herbs. We refer only to some types of perennial grasses to real lawn grasses

I must say that the most spectacular, even, emerald-green lawns, which we call parterre, usually consist of only one grain. Moreover, its appearance will depend on the correct choice of cereal for a particular site, as well as on the constant care of the lawn. Unfortunately, the use of pure grass culture in Russia is somewhat difficult. Sharp temperature fluctuations, cold winters, insufficient light, as well as low nutrient content in the soil incline us to use grass mixtures. That is, to create a certain individual, suitable for a given area, a mixture of several types of lawn grasses. It is believed that each species contained in the mixture will occupy its own ecological niche, and from this the lawn will be more resilient.

To select cereals, you need to know the following. First: if possible, use only rhizome-loose cereals, which will be discussed below. And try not to use rhizomatous (rump, bent grass, etc.), loose shrubs (perennial ryegrass, meadow fescue) and only in some cases use dense shrubs (sheep fescue, keleria). Secondly: make up a mixture of grass species that have a completely uniform bush texture and color in order to avoid spots and waviness on the lawn.

To correctly collect such a mixture of grass, you need to know the biological and ecological characteristics of some cereals.

Red fescue - Festuca rubra. Perennial rhizome-loose cereal. It has thin, narrow foliage and dark green color. The first shoots appear on the 7th day after sowing. The tillering phase begins in about 3 weeks. Has a good ability to displace weeds from the grass stand. An important positive property of fescue is the ability to maintain the green color of elastic glossy leaves even during periods of drought. The drought and heat resistance of fescue is combined with its gas and smoke resistance. Plants bush well and by the end of the first growing season they form a lawn of superior and excellent quality. Red fescue has a high cold resistance and winter hardiness. It is also better adapted to shading conditions than meadow bluegrass. Recommended for creating parterre lawns.

Meadow bluegrass- Poa pratensis. Perennial rhizome or rhizome-loose cereal. It has an emerald green leaf color. The leaf is wider than that of red fescue. Differs in a prolonged period of emergence of shoots (11-14 days after sowing) and the onset of the tillering phase (after about 30 days). Therefore, in the first year of the growing season, it forms a high-quality herbage only by autumn. Has a fairly high ability to displace weeds. Poorly tolerates dry periods, which can result in yellowing of the lawn (the death of some of the shoots). Meadow bluegrass forms an even, resilient, tear-resistant turf and a beautiful dense, intense green herbage. Positive features include: the ability to tolerate soil compaction, better than other grains, and excellent winter hardiness. Bluegrass does not tolerate high soil salinity and acidity.Not recommended for accelerated lawn creation, with the exception of roll turf technology. Can be used to create parterre lawns for autumn cereal crops.

Another cereal that, in a place with meadow bluegrass and red fescue, is suitable for creating an excellent lawn - Polevitsa shoots- Agrostis stolonifera. This is a perennial short-rhizome cereal. The field bale develops long aerial creeping shoots. Seedlings are observed already on the 5th day after sowing, the greening of the lawn occurs on the 8-10th day. The foliage is similar in structure to the leaves of meadow bluegrass. The color is rich, light green, noticeably different from other types of cereals. It has a good ability to displace weeds, an increased tillering intensity and forms a good lawn already in the first year under favorable conditions. Quite demanding on humidification conditions. Easily tolerates excessive moisture and shading. The disadvantage is the poor tolerance of heavy soils - aerial shoots of the plant root poorly, forming so-called "beards", which can turn yellow under unfavorable climatic conditions,and also be damaged when cutting and combing with a rake. Due to poor compatibility with other types of lawn grasses for leaf color, it is not recommended to use in grass mixtures.

The cereal used in Russia most often for the creation of urban lawns - Perennial chaff (perennial ryegrass)- Loliun perenne. This is also a perennial loose cereal. It has a characteristic luster of a leaf blade and a dark green color. The first shoots appear on day 4-5, full greening of the site can be observed in a week. Differs in the most intensive development in the first year of life. Forms a dense, uniform herbage quickly, easily displacing the weeds present. Forms a lawn of good quality. In the first year of development, it noticeably surpasses other types of lawn grasses, which is due to the popularity of this type of cereal. However, the plant is characterized by aggressive regrowth, which requires frequent mowing. In addition, the cereal is considered not long-lived (up to 3 years). Recommended for accelerated creation of temporary parterres. In general, pasture ryegrass is unsuitable for creating a long-term lawn.

Sheep fescue- festuca ovina is also a characteristic lawn grass. It has a very thin, harsh foliage and a dark green-bluish color. Development phases are similar to red fescue. The grain is very resistant to dry conditions and also to trampling. It has a low energy of regrowth, which makes it possible to mow the grass stand less often. Due to the bush structure, it does not fight weeds well and does not form a good projective cover in the first year of life. When creating a lawn from sheep's fescue, careful soil preparation (checking for weed seeds) and weed control with herbicides are recommended. In addition, at low seeding rates, there is a slight overhanging of the plots. Recommended for the creation of parterre lawns as a component for red fescue, as well as for creating grass mixtures.

Thus, for the construction of high-quality lawns, lower rhizome-loose grasses are most suitable: meadow bluegrass and red fescue. In damp habitats, fed by closely lying groundwater, a stolon-forming species can be used: the shoots bent. For very dry habitats with light soils, a dense shrub cereal is suitable: sheep fescue.

To create a quick effect when arranging lawns, a loose bush semi-top grain is used:

The listed cereals are quite widespread and their seed production is well established.
