Ground Cover Plants General Usage Areas;  Ground cover plants used in large areas instead of grass Used to preserve the general appearance and use of the lawn: This group of ground cover plants requires a proper soil mix.  As with lawns, there are problems with weed control.

Dichondra, lippia, wrapping thyme, downy thyme are examples of this type of ground cover plants.

  • Ground cover plants with irregular structure: This type of ground cover is used for hard-to-reach places.  Cotonoaster dammeri, Cotonoaster microphylla, Rosmarinus officinalis can be given as examples.
  • Ground cover plants are generally used in gardens of houses, factories, schools, hospitals, areas controlled by municipalities, medians of highways and pedestrian crossings.

The advantages of ground cover plants are

  • Ground cover plants functionally prevent erosion and can be used on sloping lands as they absorb rain water.  It provides weed control by preventing the passage of light.
  • It absorbs the sounds in areas with heavy traffic and reduces the noise.  It prevents evaporation from the soil with its green cover.
  • Rotting leaves, which act as mulch, continuously form residues and ensure the renewal of the soil.  Remains of old leaves and other plants rot at the bottom of ground cover plants and are mixed into the soil by earthworms.

Many ground cover plants are not print resistant.  Although grass plants are used in such places, ground cover plants are used to delimit and shape the areas. Bulbous ground cover plants are used for seasonal effect. It creates similar or different colors, structures and shapes in large areas covered by groundcovers. Ground cover plants are used in landscape planning, rocks, rock gardens, patios and terraces, and also in historical gardens.

Woody Groundcover Plants;  Ground cover plants in this group are plants taller than 30 cm.  Woody ground cover plants may look stunted in a medium-sized garden, but may not have the same effect in a small garden.  In this respect, there is no definite rule limiting ground cover plants. A groundcover of a certain size may be ideally effective in an open, uneven area, but may not be suitable for a confined space such as a front or inner courtyard.  There is a very close relationship between the size of the area and the height of the plant. Ground cover plants differ from each other in terms of height and some features. E.g; climbing, spreading, evergreen, deciduous, evergreen, like those whose organs disappear in autumn and re-sprout in spring. Ground cover plant names
