Flower Dwarfing Techniques: Learn to Master Them Easily in 5 Steps

With the development of the flower industry, miniaturized and compact potted flowers and bonsai are increasingly favored by people, so flower dwarfing technology is showing more and more vitality. The main dwarfing cultivation techniques are:

1. Asexual propagation. Asexual propagation methods such as grafting, cuttings, and layering can all achieve a dwarfing effect, shortening the flowering stage of flowers, reducing plant height, and making the plant shape compact. Grafting can achieve dwarfing by selecting dwarf varieties. For cuttings, the plant height can be determined by considering the cutting time; for example, chrysanthemums cut in late July can be dwarfed and lodging controlled. In addition, the bud-bearing cutting method can allow the tall dahlia to be planted in a pot with a diameter of just over ten cm, with a plant height of only about a chi and large, brightly colored flowers. Chrysanthemums are dwarfed through axillary bud propagation.

2. Shaping and pruning. Through shaping, remove the main branch when the plant is young to encourage side branches to sprout, then prune excess and poorly growing side branches to achieve a full plant shape, a low plant height, and improved ornamental value. Pruning for dwarfing by this method is mostly used for roses, salvia, rhododendrons, foliage flowers, and others. Narcissus is dwarfed by needle pricking and carving to destroy the growing points.

3. Controlled fertilization. Apply phosphorus and potassium fertilizers to potted flowers at the right time and apply less nitrogen fertilizer to control vegetative growth and achieve dwarfing.

4. Artificial stem bending. Artificially twisting the branches and trunks obstructs the plant's nutrient transport channels, slows the plant's growth rate, and achieves a low flower plant shape. It is generally used more in the production of small bonsai.

5. Use of plant growth regulators

1. Spraying salvia plants with paclobutrazol can shorten the internodes, reduce leaf area, and deepen leaf color, thereby changing the phenomenon of salvia having tall stems, thin stems, sparse flowers and leaves, and serious flower drop, and improving ornamental value. In addition, it is also often used for dwarfing flowers such as snapdragons and chrysanthemums.

2. Treating plants such as salvia with mepiquat chloride can reduce plant height by 26%, and also shorten stem nodes and increase the number of branches, improving ornamental value.

3. Treating plants with B9 can inhibit the vegetative growth of morning glory, dwarfing it by 61.5-67% during the vegetative growth period and by 40.5% at full bloom, thereby making the plant shape short, the branches and leaves compact, and the flowering concentrated. 4. Using chlormequat to inhibit the vegetative growth of petunias and others can dwarf the plant shape and improve ornamental value.

6. Radiation treatment. Some flowers can also be treated with radiation to change the plant's growth condition and thereby achieve dwarfing. For example: treating narcissus bulbs with Y rays can control narcissus growth and dwarf the narcissus plant. Treating canna with 60°C can reduce the height of canna by 30-50 cm and improve ornamental value.
