Chrysanthemum Magnum is a Dutch variety created specifically for cutting. Widely known to florists who use the culture to create bouquet arrangements. The plant is grown in open ground; it is suitable for forcing in greenhouse conditions, where it can bloom all year round. The name of the variety comes from the Latin magnus - large, great. Breeders tried to create a culture that competed with roses, and they succeeded. The chrysanthemum is not only beautiful, it can withstand long-term transportation, and also please the eye for more than a month while in a vase.
Description of single-headed Magnum chrysanthemums
Magnum is a new variety of crop that appeared relatively recently. Chrysanthemum received its varietal name because of its very large flowers.
The plant is used in ornamental gardening, included in mixborders or used as a tapeworm
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 grown en masse for cutting.
External characteristics of chrysanthemum:
- the bush is dense, compact, with erect stems that end in single flowers;
- no side shoots are formed, the structure of the vine is rigid, the surface is smooth, ribbed, light greenish;
- plant height does not exceed 1 m;
- the leaves are arranged frequently, alternately, the plate grows up to 8 cm wide and up to 15 cm long;
- the surface is smooth with pronounced veins, the edges are coarsely dissected, the color is dark green on top, silver on the underside;
- The root system is superficial.
The variety is perennial. In an unprotected area it blooms from the end of September until the onset of the first frost. It is grown in greenhouses as an annual plant.
The single-headed variety of the crop is presented in two colors. Chrysanthemum Magnum New blooms with white inflorescences. Characteristics of the variety:
- the flowers are large, growing up to 25 cm in diameter;
- dense, densely double, consisting only of reed petals with concave edges;
- hemispherical shape, hard to the touch structure;
- The outer petals are white, closer to the middle - cream, the central part has a green tint.
The core is formed by reed petals that do not fully open
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, uniformly colored in bright yellow. The shape of the inflorescence is dense, spherical, and the core is closed.
The variety does not stop growing even after cutting
Planting and caring for Magnum chrysanthemums
The conditions and planting methods for yellow and white Magnum chrysanthemums are the same. The plant is grown as an annual.The variety is not suitable as an ampelous species. It has a branched root system and in containers the flowers are smaller and not as dense as in a garden bed or flower bed.
The culture is adapted to temperate climate conditions, but early frosts in the Central zone often damage the 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 a landing site
Chrysanthemum Magnum is a light-loving plant. In greenhouse conditions, lamps are installed for additional lighting. The duration of daylight should be at least 12 hours. The culture does not tolerate sudden temperature changes, so they maintain a regime of 22-25 0C. In an open area, a sunny place is allocated for the plant. Seedlings do not react well to the north wind, so this factor must be taken into account when planting.
Chrysanthemums are not planted in poor, heavy soils; preference is given to loamy, organic-rich soil with a neutral reaction. In the spring, the flowerbed is dug up to a depth of 20 cm, compost, ash, and nitrophoska are scattered on the surface. Before planting, the nutrient mixture is embedded to a depth of 15 cm, and 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 industrial greenhouse structures, planting and cutting take place throughout the year. With the open method, they focus on the climate; most often, flowers are planted at the end of May.
The root system of the chrysanthemum develops parallel to the surface of the soil; it deepens 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 and gravel is poured into the bottom. Drainage is not used in closed structures.
- The seedling is placed vertically and covered with soil, compacted.
- The chrysanthemum is watered and mulched with peat.
The Magnum variety has a bushy form, so 40 cm is left between cuttings.
In order for the chrysanthemum to take root better, all leaves and shoots are cut off from the planting material.
Watering and fertilizing
Chrysanthemum Magnum is a moisture-loving crop, but at the same time it does not react well to high air humidity, so the greenhouse is periodically ventilated. To prevent the soil from becoming dry and waterlogged, regulate watering. The procedure is carried out only at the root, preventing moisture from entering the plants.
Large-flowered double crops require mandatory feeding throughout the entire growing season:
- When the first shoots appear, nitrogen-containing agents, urea or nitrophoska are added.
Granules are scattered near the plant and surface loosening is carried out.
- In mid-August (at the time of bud formation), superphosphate and Agricola are added.
The solution is poured under the root, avoiding contact with the above-ground part.
- At the time of the main flowering, feed the chrysanthemum 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 Magnum chrysanthemum as a perennial crop.
The frost resistance of the variety allows wintering at temperatures of -180C. To protect against cold, the plant is covered with straw. 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, the cutting method is used for propagation. The variety has a high survival rate, 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.
Chrysanthemums are propagated in a greenhouse at any time of the year; timing does not matter.
Diseases and pests
Chrysanthemum Magnum is a hybrid variety of crop with high resistance to infections. Closed cultivation takes place without problems, the plant does not get sick in greenhouses. In an open area, gray mold and downy mildew may be affected. In the fight against fungal diseases, the drug “Topaz” is used.

The main threat to the Magnum chrysanthemum in open areas is slugs; they get rid of them with Metaldehyde.
Granules are laid out around the affected and nearby chrysanthemums of any variety.
In greenhouses, the plant is parasitized by aphids; the universal remedy “Iskra” is effective against it, which also gets rid of the caterpillars of leaf miners and earwigs.
“Spark” is used to treat the plant and the soil near it, and is also used in the spring for preventative purposes.
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 growing openly in warm climates and indoors in temperate climates.
