Application in landscape design

Representatives of Japanese irises of various colors and heights are combined with all types of flowering and evergreen plants. They are in perfect harmony with ornamental shrubs. The main condition for creating compositions is an open area without shading, as well as a neutral or slightly acidic soil composition.

Flower beds (iridariums) created from irises with different colors of flowers are popular with designers and gardeners. Low-growing varieties are used to decorate rock gardens, they also create mixborders in the style of a Japanese garden.

Description and photos of design ideas for the use of Japanese irises:

  1. Planted along the edge of the flower bed.

    Japanese irises favorably emphasize evergreen shrubs and undersized flowering plants

  2. Designs are made of natural stone.
  3. They decorate the shores of an artificial reservoir.
  4. Mass planting is used to tamp the edge of the lawn.
  5. Mixborders are created with simultaneously flowering crops.
  6. They decorate the territory of rockeries.
  7. Placed in mass planting along the garden path.
  8. Decorate garden areas.
  9. They create Japanese-style compositions.

Breeding features

You can propagate a culture by seeds, but this method is more often used to breed new varieties. To obtain seedlings of Japanese irises, seeds are sown harvested at the end of the growing season. The seed breeding process is long, the seedlings will bloom only in the third year.

Japanese irises are propagated on the site by dividing the bush or root shoots. The difference between the methods is that in the first case, the plant is removed from the soil and cut into pieces, in the second, a piece of root with shoots is cut off with a shovel.

When dividing an adult bush, at least three leaf rosettes should remain on one root section

Planting and caring for Japanese irises

Japanese iris (pictured) is an unpretentious plant, so planting and care will not cause difficulties even for novice gardeners. The place allotted for the culture must satisfy its biological needs. Preparatory measures for winter play an important role in the cultivation of irises, especially in the temperate climatic zone.


Japanese irises are placed in the Southern regions in spring (April) or autumn (October). For the Central and Middle Lane, work is not recommended to be carried out in the fall, because seedlings have a weak root system, which does not overwinter even with careful cover. Japanese irises are planted in open ground in early May, when there is no threat of return frosts, and the soil warmed up to +15 0With or in the summer, so that the seedling has time to root well.

Site selection and soil preparation

Japanese irises are light-loving flowers that lose their decorative appearance in the shade. Therefore, the following requirements are imposed on the site:

  • the place should be open, protected from the influence of the north wind;
  • do not use areas in the shade of large trees with a dense crown;
  • the soil is suitable neutral or slightly acidic, aerated, fertile, light;
  • terrain with stagnant groundwater is not allowed, but the culture feels comfortable along the banks of water bodies.

The allotted flower bed is dug up, weed roots are removed, organic matter is introduced. Wood ash is not used for growing Japanese irises, and fertilizers containing alkali are not recommended. Before work, mix a nutrient substrate from sod soil, compost and peat, add nitrogen-containing agents and potassium.

Landing algorithm

If the planting material is with a peduncle, then the central stem is cut at the root, but on the sides there must be leaf sockets (children).

With a sharp knife, carefully cut off the link that has faded

Planting sequence of Japanese irises:

  1. Leaves are cut at an angle.
  2. Dig a hole along the height of the root, taking into account 10 cm for the substrate layer.
  3. The seedling is placed in the center, the roots are untangled if necessary.
  4. Gently sprinkle with soil over the growing buds.
  5. The soil is slightly compacted so as not to damage the surface roots of the iris.
  6. The seedling is watered, you can cover the soil with mulch.

Care features

Caring for Japanese irises consists in fulfilling simple requirements:

  • the plant is spud and covered with mulch, in spring, this event excludes the appearance of weeds and retains moisture;
  • watered regularly to prevent the soil from drying out. It is not necessary to overfill the seedlings;
  • they are fed in spring with complex fertilizers, the entire period of growth can be applied to liquid organic matter.

In the fall, the aboveground part is cut off, superphosphate is introduced, and covered with a layer of straw. Young irises can be insulated with spruce branches.

Diseases and pests

Japanese irises do not get sick, the only problem can be stagnant water and cold weather, which increase the likelihood of root rot, but this rarely occurs. Thrips parasitize the plant, they get rid of them by cutting off damaged areas and treating them with insecticides.


Japanese irises are represented by numerous varieties with a variety of colors, shapes and sizes of flowers. They grow a culture for cutting and decorating plots, gardens, flower beds. Japanese irises are unpretentious, do not get sick, and are rarely affected by pests. They do not tolerate shaded areas and moisture deficit.
