Characteristics: strong branching, low branching position and compact plant type. The taproot is not obvious, the lateral root is developed and there are many fibrous roots. This dwarf plant has been optimized for many years.

2. Prepare the culture soil: the culture soil is the basis for the good growth of potted flowers, which requires rich organic matter, good aggregate structure, fertility and looseness, and comprehensive nutrition. It is made of humus soil, garden soil, pond mud, peat soil, river sand, organic fertilizer, phosphate fertilizer, bone meal and plant ash. The pH value is slightly acidic to slightly alkaline, which should be adjusted according to the adaptability of different flower varieties to the pH value. Choosing the corresponding nutrient soil can make the plants strong and the branches and leaves more compact.

3. Cut off the radicle and put it into the pot: put the flower seedlings into the pot, cut the radicle short, spread the lateral roots around when transplanting, and fill the soil in layers.

4. Changing pots, controlling fertilizer and preserving water: potted flowers are mainly nutritious soil. Therefore, it is necessary to constantly update the culture soil by changing pots, generally from 1 year to 2 years/time. According to the growth of plants, small pots should be replaced with large pots, and old soil should be replaced with new soil. Combined with changing pots, pruning is carried out to improve the tree structure and promote short and strong. Control nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer, avoid excessive watering, and prevent excessive growth, rotten roots and dead seedlings. Especially in the peak growth period, it is necessary to do a good job in water and fertilizer control, so that the soil is wet and dry alternately, save water and lose weight, promote stable growth, and achieve multi-branches, multi-flowers, short branches and short plants.

5. Strengthen pruning and shaping: when the flowers and trees grow to a certain height, pick the heart in time, adopt branch opening angle and twisted branch shaping to inhibit the growth advantage of the top, shorten the vegetative growth cycle and promote flowering and fruiting.

Dwarfing technology is an essential technology to learn bonsai cultivation. Once mastered, large plants and flowers, no matter how big or tall, can change from "high song whistling" to short and tight.
