Besides the usual garden grass lawn, there are other types of lawns:
Mauritanian lawn is a lawn, composed of mixtures of perennial and annual grasses. Such lawn is called the Mauritian, and it vivifies the plot, pleasing eyes with its multicolored palette. As a rule, the grassy mixture of this lawn consists of 10 - 15 different annual grasses. It may be forget-me-not, red and blue flax, eshsholtsiya, iberis, alissum, annual poppies, carnations Chinese, cornflowers, calendula, chamomile, etc.
In the base of the Mauritanian lawn, as a rule, we find red fescue and meadow-grass, which are very well combined with other herbs. Annuals plants should be chosen in such order that spring flowers combine with the autumn one. So Mauritanian lawn will rejoice you with all variety of colors from spring to autumn.
If you choose such lawn, remember that second year he will fade because of the death of annuals, if not to sow them again. Mauritanian lawn should be shorn usually in spring and autumn after fading of all annuals.
Parterre lawn is a lawn, generally used for compositions in the regular style. These lawns should be made according to high quality standards. They must be perfect, with a uniform color and a thick growth of grass. Requirements for a ground lawn are much stricter than for the park (garden) lawn.
To prepare the ground for planting of the parterre lawn, you must work hard : the soil must also be of high quality: fertile, well-drained and well aligned. Generally, only one of the parterre grass is used. It is possible to use a mixture of the two grasses, suitable for the structure and similar in the speed of growth. For the parterre lawn only resistant to damage, drought and frost the grass is to be used. Ovsyannitsa red and Poa pratensis are ideal grass to sow a good parterre lawn.
They require a more thorough care after planting, than the garden (park) lawn, namely, regular watering and grooming. Meadow grass is very picturesque. Usually it is used as the basis of landscape composition over large areas, in parks and gardens for public purposes. For meadow grass, there are several types of mixtures, which are usually have in base 3 - 5 species of perennial grass plants with the addition of small amounts of clover and yarrow. Following plants could be good composition elements for meadow grass : ryegrass years, Birds foot, bent grass, meadow fescue, white clover, timothy, etc.
Preparing the soil for the lawn.
For subsequent seeding of the lawn thickness layer of fertile soil even in terms of sediments must be at least 10-15 inches. There are no restrictions in maximum thickness : the more fertile land you put under your lawn, the better it will grow. Phosphate fertilizers are also used at a rate of 0,2 - 0,4 kg per 1 square meter.
If the area is disposed to water-logging, you need to have a drainage under the fertile layer put, because lawns can not stand moisture.
Second necessary condition for the smooth growth of the lawn is a careful leveling of the soil, removing of lumps, seals, irregularities, elevated parts of the earth, cutting and filling of cavities . Ideally, the surface should be completely flat.
It is not recommended to plant the lawn immediately after filling the earth . The soil should be kept for two - three months for the shrinkage. Even better, if you can leave it for the winter.
Before you sow the lawn, you must repeatedly rake it and remove all weeds. If you walked through the soil and there are no deep holes from your shoes on it, it means your soil is ready for seeding a lawn.
The optimum depth of seeding lawn grasses is 0,2 - 0,4 inch, if you sow lawn grass more than 1 centimeter depth, they can not germinate. The optimum seeding rate - 15 - 35 grams per square meter of land, depending on the variety of herbs.
You should follow instructions, written on the package of seeds, or the lawn may grow not successfully. Excess seeding of slow-growing grass provokes roting of grass-roots in the heat, scanty seeding causes "bald spots" in the lawn.
The causes of bald spots can become not only a rare seeding, but "rolling up" of the earth after planting, inadequate watering, walking on immature shoots, any mechanical damage to the surface, violation of terms of mowing.
