What are ITO peonies?

ITO peonies are a relatively new group of garden peonies, valued by flower growers all over the world for the unique beauty of their flowers, abundant and long flowering, relative unpretentiousness and high winter hardiness.

ITO-peonies got their name in honor of the famous Japanese scientist and breeder Toichi Ito, who in the middle of the last century was actively engaged in the selection of garden peonies. At that time, many dreamed of creating large-flowered varieties of herbaceous peonies with yellow flowers. Toichi Ito decided to achieve this goal by transferring the outstanding qualities of yellow-flowered treelike peonies to herbaceous ones. The breeder carried out more than 1200 crosses of herbaceous and tree-like forms of peonies, as a result of which several plants were obtained with the desired yellow color of the flower.

ITO peonies have inherited the best qualities of their parental forms:

  • very large flowers of original pastel colors;
  • abundant and long flowering;
  • beautiful dark green foliage;
  • powerful herbaceous stems that do not require a garter;
  • high winter hardiness.

Agrotechnics of ITO-pions

ITO peonies should be planted in elevated and well-lit areas with a low level of groundwater. ITO-peonies will feel best of all on loamy, well-fertilized soils with a high humus content. The acidity of the soil should be slightly alkaline or neutral. The best time for planting ITO peonies is the end of August - beginning of September. The optimal size of the planting pit is 50-60 cm in depth and 60-80 cm in diameter. "Delenki" of ITO-pions are planted in such a way that they are located strictly in the center of the planting pit and with a slight slope, and the buds of renewal are at a depth of 3-5 cm from the soil surface level. Planting pits are filled with pre-prepared nutrient soil, consisting of a mixture of humus and garden soil with the addition of a small amount of phosphorus fertilizers.For deoxidation, a small amount of ash or dolomite flour should be added to the soil. In the case of purchasing planting material for ITO-peonies with a closed root system, carefully, without disturbing the earthen coma, transfer the plant from the container into the planting hole, after which, observing the required planting depth, fill the planting hole with nutritious soil. After planting, the soil surface should be mulched to maintain its moisture and air permeability.After planting, the soil surface should be mulched to maintain its moisture and air permeability.After planting, the soil surface should be mulched to maintain its moisture and air permeability.

Caring for ITO peonies is generally the same as for ordinary herbaceous peonies. In the summer, plants require regular watering and feeding. It is especially important to provide plants with a sufficient amount of moisture in late spring - early summer, when there is an active growth of stems and the formation of buds, as well as at the end of summer, when the plants are actively forming renewal buds. It is best to water the ITO peonies in the evening. In hot weather, it is desirable to make daily surface moistening of the soil. ITO-peonies are watered exclusively "at the root". It is highly discouraged to use the sprinkling method, since the plants are very easily infected with fungal diseases. After each watering, the soil under the peony bushes should be loosened. The more oxygen the roots receive, the more beautiful and magnificent the flowering will be.

Subject to proper agricultural technology, ITO-peonies do not require any additional feeding in the first two years after planting. Plants should be fertilized starting from the third year of their cultivation. In spring and early summer (during active growth and budding), plants are fed with nitrogen fertilizers, and at the end of summer (during the formation of renewal buds) - with a phosphorus-potassium complex.

The buds that appear in the first two years should be removed immediately, since the flowering of young plants can significantly weaken their development. In adults, already well-formed plants, the first pruning is done in mid-June. At this time, "old" dried flowers are removed, which contributes to the laying of new buds of renewal. The more they are formed, the more magnificent and beautiful will be the flowering of ITO-peonies for the next year. When pruning, it is also important to carefully remove any leaves and petals that have fallen to the ground. This is done to reduce the risk of developing fungal diseases. The second time, ITO-peonies are cut in the fall - in the first half of October. This time, almost the entire aerial part of the plants is removed, after which it is burned to exclude the contamination of the plantings with fungal infections. When removing the aboveground part of the ITO-peonies in the autumn, rememberthat the main buds of renewal, ensuring the further development and flowering of plants, are formed on the roots in the depths of the soil.

ITO-peonies are very winter-hardy plants, therefore they do not require mandatory shelter for the winter. In especially cold winters, you can sprinkle the planting pits with peonies with a layer of well-rotted manure. In the spring it will need to be carefully removed, taking care not to damage the tender young shoots of plants.

ITO-peonies begin to bloom in the second or third year after planting. Their first flowers are usually not very beautiful - they have an irregular shape and curved petals, but then everything returns to normal, and the plants begin to delight their owners with luxurious flowering. According to most gardeners, ITO peonies gain the maximum beauty in the fourth or fifth year of their development.
