Description of single-headed chrysanthemums Magnum
Magnum is a new kind of culture that has appeared relatively recently. Chrysanthemum got its varietal name because of its very large flowers.
White chrysanthemum Magnum is in perfect harmony with crimson roses and evergreen conifers. But the main purpose of the variety is commercial, so it is massively grown for cutting.
External characteristics of chrysanthemum:
- the bush is dense, compact, with erect stems that end with single flowers;
- lateral shoots are not formed, the structure of the vine is hard, the surface is smooth, ribbed, light greenish;
- plant height does not exceed 1 m;
- leaves are located often, alternately, the plate grows up to 8 cm wide, up to 15 cm long;
- the surface is smooth with pronounced veins, the edges are coarsely dissected, the color is dark green above, silvery on the lower side;
- the root system is superficial.
The variety is perennial. In an unprotected area, it blooms from late September until the onset of the first frost. In greenhouses, it is grown as an annual plant.
The single-headed crop variety is presented in two colors. Chrysanthemum Magnum New blooms with white inflorescences. Variety characteristic:
- flowers are large, grow up to 25 cm in diameter;
- dense, densely double, consist only of reed petals with concave edges;
- hemispherical shape, the structure is hard to the touch;
- outer petals are white, closer to the middle - cream, the central part with a green tint.
Chrysanthemum Magnum Yellow has been in cultivation since 2018, the new variety is distinguished by yellow flowers. Magnum Yellow is distinguished by a shorter stem, not exceeding 80 cm. The petals are glossy, painted evenly in a bright yellow color. The shape of the inflorescence is dense in the form of a sphere, the core is closed.
Planting and caring for chrysanthemums Magnum
The conditions and methods of planting for chrysanthemum Magnum yellow and white are the same. The plant is grown as an annual. The variety is not suitable as an ampelous type. He has a branched root system and in containers the flowers are smaller and not as dense as in the garden or flower bed.
The culture is adapted to temperate climates, but early frosts in the Central Lane often damage flowers, so it is better to grow the Magnum variety in greenhouse structures. Any cultivation method is suitable for the South.
Selection and preparation of the landing site
Chrysanthemum Magnum is a light-loving plant. In greenhouse conditions, lamps are installed for additional lighting.Daylight hours should be at least 12 hours. The culture does not tolerate sudden temperature changes, therefore, they support the 22-25 mode 0C. In an open area, a sunny place is allocated for the plant. Saplings do not react well to the north wind, therefore, this factor must be taken into account when planting.
They do not plant chrysanthemums in poor, heavy soils; preference is given to loamy, organic-rich soil with a neutral reaction. In the spring, the flower bed is dug to a depth of 20 cm, compost, ash, and nitrophosphate are scattered on the surface. Before planting, the nutrient mixture is embedded to a depth of 15 cm, the soil is abundantly moistened.
Landing rules
The timing of planting chrysanthemums depends on the method of cultivation. The crop can be planted in the greenhouse at any time.
The Magnum variety was created specifically for forcing; in production greenhouse structures, planting and cutting takes place throughout the year. With the open method, they are guided by the peculiarities of the climate, most often flowers are planted at the end of May.
The root system of a chrysanthemum develops parallel to the surface of the soil, it deepens by no more than 25 cm.This indicator is taken into account when planting.
Sequence of work:
- The soil is watered with hot water with the addition of manganese.
- In greenhouses, furrows are made 25 cm deep. In the open ground, holes are dug, at the bottom of which gravel is poured. In closed structures, drainage is not used.
- The seedling is placed vertically and covered with soil, compacted.
- Chrysanthemum is watered, mulched with peat.
The shape of the Magnum variety is bushy, so 40 cm is left between the cuttings.
Watering and feeding
Chrysanthemum Magnum is a moisture-loving culture, but at the same time it reacts poorly to high air humidity, so the greenhouse is periodically ventilated. To prevent the soil from being dry and waterlogged, regulate watering. The procedure is carried out only at the root, preventing moisture from entering the plants.
Large-flowered terry crops require mandatory feeding throughout the growing season:
- When the first sprouts appear, nitrogen-containing agents, urea or nitrophosphate are added.
- In mid-August (at the time of bud formation), add superphosphate and Agricola.
- At the time of the main flowering, the chrysanthemum is fed with potassium sulfate.
The frequency of the procedure is once every 3 weeks. During watering, fertilize with liquid organic matter.
Reproduction
The Magnum variety does not produce seeds for generative propagation. In greenhouse structures, the plant is cultivated as an annual. In an open area in a warm climate, it is possible to grow Chrysanthemum Magnum as a perennial crop.
The frost resistance of the variety allows wintering at a temperature of -180C. Cover the plant with straw to protect it from the cold. Propagated by dividing the mother bush. The procedure can be carried out at any time, but it is better to do it in the fall, after flowering.
Most often, cuttings are used for breeding. The survival rate of the variety is high, so there are no problems with reproduction. For open ground, the material is harvested in the fall, the cuttings are placed in a fertile substrate and left at a temperature of +14 0C, in the spring they are taken out to the site.
Chrysanthemum is propagated in the greenhouse at any time of the year, the timing does not play a role.
Diseases and pests
Chrysanthemum Magnum is a hybrid crop with a high resistance to infections. Cultivation in a closed way takes place without problems, the plant in greenhouses does not get sick. In an open area, it is possible to be affected by gray mold, downy mildew. In the fight against fungal diseases, the drug "Topaz" is used.
The main threat to Chrysanthemum Magnum in open areas is slugs, they get rid of them with "Metaldehyde".
In greenhouses, the plant is parasitized by aphids; the universal remedy "Iskra" is effective against it, which also eliminates the caterpillars of the mining moth and earwig.
Conclusion
Chrysanthemum Magnum is a tall shrub with single flowers at the tops of the stems. The Dutch variety is cultivated for cutting, less often used as an ornamental plant in the landscape. Chrysanthemum Magnum is available in two colors - white and yellow. The crop is suitable for open cultivation in warm climates and indoor cultivation in temperate climates.
