The layer of mulch is a very effective protection of the ground surface. The material making up the litter can be: needles, peat, shredded bark, shredded branches, chopped straw, etc.. The thickness of the layer may vary depending on the material used 5-10 cm. In order to prevent the litter from slipping, it is necessary to make furrows or holes on the surface of the slope with the use of various tools. In the resulting unevenness, water retains better and the litter layer resists better.

The litter is covered to prevent being blown away by the wind 2 – 5 centimeter layer of earth, with which the seeds of various plants can be mixed, e.g.. grasses. The surface of such strengthening can be rolled with a smooth or whale roller, if they can be led along the slope surface with the help of special devices. Mechanized methods of sowing seeds and arranging mulch on the slope surface and strengthening it with a bituminous binder are discussed in another article.

The methods of protection against erosion include covering the slopes with a layer of straw and holding it with a net nailed to pegs.. This method gives a great guarantee of protection against erosion, and at the same time it creates perfect conditions for the colonization of various plants.
Another, a more complex method is to make thresholds on the surface of the slope using hammered pegs and fascine bundles based on them. The space between the thresholds is filled with fertile soil, and after it has been leveled, the entire surface is covered with a layer of mulch.

The surfaces of slopes with a significant slope are often covered with special hexagonal concrete slabs with openings enabling the introduction and maintenance of vegetation.

The surfaces of the slopes can be planted with various species of garden plants, creating interesting compositions of high decorative value. A variety of carpet plants with numerous creeping shoots are particularly suitable for this purpose, strongly rooted, forming underground runners, rhizomes, etc..

The inclined surface intended for the cultivation of various plants can be formed in a stepped manner and reinforced with specially arranged stone blocks.

Such formed slopes also provide good growing conditions and very good opportunities to display the decorative value of the plants planted there..

When securing the slopes, it is important to remember not to allow water to run down their surface from the areas beyond the slopes. For this purpose, special gutters should be built in front of the edge of the slope.

tmp643-2A slope gutter made of prefabricated elements, made in the part above the scarp.

Their task is to drain water along the slope. The bottom of the gutters should be strengthened. Making unreinforced gutters (permeable to water), especially near the edge of the slope, may lead to soil supersaturation with water and cut the slope.
