The propagation methods of forever菊花
Comprehensive introduction to the propagation of flowers forever菊花, including the propagation methods of forever菊花, detailed information is as follows:
Forever菊花 is commonly propagated by cutting, dividing, grafting, and tissue culture methods.
(1) Cuttage can be divided into bud cuttage, young shoot cuttage, and leaf bud cuttage. Bud cuttage is carried out in autumn and winter by cutting the plant's basal buds. The criteria for selecting buds are those that are farther from the plant and have full buds. Remove the lower leaves, insert them into pots or beds in greenhouses or greenhouses at a spacing of 3-4 cm between plants and 4-5 cm between rows, maintain a room temperature of 7-8°C, and transplant them outdoors when it warms up in spring. Young shoot cuttage, the most widely used method, is done in April and May by cutting young shoots 8-10 cm long as cuttings. At a temperature of 18-21°C, roots form in about 3 weeks, and can be planted after about 4 weeks. For outdoor beds, the medium should be fine sand, and the bed should be shaded. Full light mist beds do not require shading. Leaf bud cuttage involves cutting a leaf with an auxiliary bud from a shoot for propagation, this method is only used for propagating rare varieties.

(2) Division is usually done around Qingming Festival, by digging up the plants and separating them according to the natural shape of the roots, and then planting them in pots.
(3) Grafting To make chrysanthemums grow strong and healthy, for creating "Ten Auspicious Ornament" or large standing chrysanthemums, grafting with yellow wormwood or green wormwood as the rootstock can be used. Sow the wormwood seeds in autumn, and either plant them in a greenhouse in winter or in a warm bed in March. Transplant them into pots or fields in late April when the seedlings are 3-4 cm tall, and perform cleft grafting on sunny days in May-June.
(4) Tissue culture The propagation of chrysanthemums using tissue culture technology has the advantages of rapid propagation, large number of seedlings, virus-free, and maintaining varietal characteristics. The basic culture medium is MS, supplemented with an appropriate amount of plant hormones, pH 5.8. Use the tip of the chrysanthemum stem, young stem, or flower bud as the explant, cut into 0.5 cm segments for inoculation. The culture room temperature is 25°C ± 1°C. The light intensity is 3000-4000 lux for 8 hours a day. After 1-2 months of culture, seedlings can be induced.
