Grafting, cutting, layering and other asexual propagation methods can achieve dwarfing effect, shorten flowering period, reduce plant height and compact plant type. Grafting can be dwarfed by selecting dwarfing varieties. The cutting can be determined by considering the cutting time. For example, chrysanthemums can be dwarfed in late July to control lodging. In addition, dahlias with tall plants can be planted in pots with a diameter of more than ten centimeters by cutting with buds. The plant height is only a few feet, and the flowers are large and gorgeous. Chrysanthemum is dwarfed by the propagation of horn buds.

Second, shaping and pruning

Through shaping, the main branches are cut off when the plants are young to promote their germination, and then too many side branches with poor growth are cut off to achieve full plant shape, low plants and improve ornamental value. This method is often used to dwarf Chinese rose, bouquet of safflower, azalea and foliage flower. Narcissus destroys the dwarfing of growing points by acupuncture and carving.

Verb (abbreviation of verb) uses plant growth regulator.

1. Spraying 40 ppm ~ 80 ppm paclobutrazol (PP333) on a bunch of red plants can shorten the internodes, reduce the leaf area and deepen the leaf color, thus changing the phenomena of thin stems, sparse flowers and leaves and serious foot drop, and improving the ornamental value. In addition, flowers such as snapdragon and chrysanthemum are often used for dwarfing.

2. When mepiquat chloride (DPC) with 100ppm is used to treat plants such as Salvia splendens, the plant height can be reduced by 26%, the stem nodes can be shortened, the number of branches can be increased, and the ornamental value can be improved.
