Hello, Victoria.

There are several reasons for the lack of flowers in chrysanthemums. For the successful development, growth and flowering of one of the most beautiful autumn plants, it is necessary to observe a number of agrotechnical techniques and the subtleties of growing. Immediately, we note the fact that only varieties of garden chrysanthemum (Ch. X hortorum = Dendranthema i hortorum) combined in a form of hybrid origin called "Korean chrysanthemum" can winter in central Russia. To date, there are many varieties of this plant. They are distinguished by late summer and autumn flowering, resistance. According to the doctor of biological sciences, professor R.A. Karpisonova, the most promising varieties for our region are:

  • Malchish-Kibalchish,
  • "Mascot",
  • "Radiant",
  • Kupava
  • Lada
  • Edelweiss,
  • Hebe
  • Citrus and other undersized and early flowering specimens.

Varieties of chrysanthemums differ in flowering periods with a peak in August-September, as well as in height (from 25 to 100 cm), size and color of inflorescences. The plant is characterized by a spherical shape of the bush, density and continuous abundant flowering. To improve branching, shoots can be pinched (about a month passes between pinching and budding). Faded inflorescences need to be removed - this also prolongs flowering. The earliest low varieties usually bloom in mid-July. For tall varieties, the deadlines are postponed, but their flowering continues until the first snow.

We advise you to pay special attention to the choice of a place for planting the queen of the autumn garden. Chrysanthemums prefer open to the sun, sheltered from the wind areas with close to neutral, rich soils without waterlogging - with excess moisture, the roots of the plant rot. If the soils on the site are acidic, they must be produced by adding dolomite flour or lime to the soil. Before planting, 10–20 kg of humus per 1 square meter is introduced, fertilizers are embedded in the soil to a depth of 20–25 cm. Mineral fertilizing is carried out at the beginning of the growing season (complex), and phosphorus-potash is used during budding. It is best to transplant chrysanthemums in the spring with a large lump of land. Autumn planting and transplanting greatly reduces winter hardiness and the chances of a successful wintering.

It is worth noting that for chrysanthemums winters with a thin snow cover or its temporary absence are very destructive. Therefore, gardeners often resort to the use of shelters made from a layer of fallen leaves (well, if it is oak leaves) or spruce spruce branches. Before wintering, stems are trimmed to a height of 15-17 cm. The main thing is that the flowers should not be torn out on the street under cover and aired. If a chrysanthemum variety is thermophilic or blooms later, it is better to dig, cut and store it in a dry room with an air temperature of + 2 ... + 4. Many gardeners do not leave chrysanthemums to winter in the ground, but resort to cuttings. The bush is dug up in the fall and carried to be stored in a cool room. In late May - early June, the plant is propagated by cuttings, which are planted in a permanent place in the garden. It is such young specimens that bloom for a long time and plentifully.

So, we have listed the basic requirements for agricultural technology and the cultivation of chrysanthemums. These are the advantages that you yourself can create for your beloved perennials in the garden, thereby increasing the chances of a colorful and long flower show. But, unfortunately, there is one point that, perhaps, will reduce all your efforts to a minimum - this is the weather factor. Even if you do everything right, surprises from mother nature may not allow buds to form in time. In this case, even in October, you will not wait for flowers.

Flowering of chrysanthemums very often depends on how favorable the weather conditions were during the growing season. Climatic phenomena directly affect the endurance and winter hardiness of plants. This includes the ability of the varieties to withstand severe winter frosts, resistance to early cold, temperature extremes, thaws at the end of winter and a sharp return cold snap. In plants, the root system is the most vulnerable. The roots can be severely damaged in years with stagnant waterlogging, as well as in snowless winters, when the absence of snow cover is combined with a sharp cooling. Remember, this situation happened the year before last in winter. In many areas of the chrysanthemum, it’s not that they did not bloom, they simply died. This year, climatic "cataclysms" do not cease to amaze us. Late spring, a cold, off-summer June, with lingering rains pushed off flowering in many perennial crops. In the Moscow region, peony flowers continued to appear in the first ten days of July, which is not typical of varieties whose peak flowering occurs at the end of June. In 2017, the weather factor displaced vegetation processes by an average of two weeks, thereby postponing the flowering time for perennial chrysanthemums. Perhaps you did not see the festival of autumn colors precisely for this reason.

To have time to rejoice at the wonderful flowers of the autumn queen chrysanthemum at your dacha, try to resort to the method of grafting the mother plant in the spring, and also use the most undersized and early flowering varieties on your site. For example, the curb variety "Pastoral" up to 30 cm high in caramel pink color. Or Target of foreign selection with contrasting pink inflorescences and a burgundy middle. The spectacular variety "Cherry Orchard" up to 45 cm high will decorate your site with flowers of a noble cherry shade, and bright yellow will add a "Golden Beehive", reminiscent of a honeycomb.

It is interesting! You can attend an unforgettable autumn show in Japan, where traditionally September 9 is a holiday-exhibition of chrysanthemums. In Tokyo, you can enjoy fantastic expositions at Shinjuku-geen Park and the Shinto Shrine of Yushima Tenjin. In Yokohama, it is Sankeyen Park. There you can see not only the whole variety of chrysanthemums, but also many realized ideas and fantasies with the help of the same plant, including traditional Japanese dolls of flowers or chrysanthemum trees skillfully formed by a master with floral tiers, as well as fragments of the Japanese landscape created for contemplation and beauty.
