Open Field Cultivation of Garden Chrysanthemum

Chrysanthemum x morifolium Ramat.

Growing garden chrysanthemums in the open field is determined by the cultivar's photoperiodism and winter hardiness. Cultivation techniques require managing flowering dates, protection against frosts, and specific overwintering methods, including digging up mother plants or using plastic covers.

In the reference 41 varieties crop Florist's daisy, where this is mentioned in the description.

Large-flowered cut varieties are characterized by long growing seasons, which often prevents them from blooming before autumn frosts when grown in the open field. For these, temporary plastic frames are used, or plants are transplanted into containers for final maturation in greenhouses. Varieties of the Multiflora group are distinguished by their genetic ability to form a spherical bush without pruning; however, they require high light intensity, as shading leads to stem elongation and loss of shape.

Overwintering of the crop depends on its frost resistance: Korean hybrids require mulching or hilling, while less hardy Indian varieties need to be dug up and stored at temperatures from +2 to +5 degrees Celsius. An important feature of industrial chrysanthemum propagation is a low rate of natural vegetative division, which makes the use of in vitro micropropagation methods essential for producing high-quality planting material.
