Begonia flower is one of the unique flower species in China, which is called? Fairy in flowers? , deeply loved by people, let me tell you the indoor begonia flower cultivation methods and precautions, I hope it will help you!

indoor begonia flower cultivation method

the best breeding time: begonia flower is propagated in Yichun and autumn.

the best soil for growth: the planting of begonia flowers on the soil requires a slightly acidic sandy loam rich in humus, loose and well-drained.

growth humidity requirements: when the weather is hot, the begonia flowers should be sprayed with water to the surrounding air to maintain a certain air humidity.

optimum growth temperature: the optimum growth temperature of begonia flower is 15 ~ 25℃.

optimal growth light: most begonia flowers belong to positive flowers. Positive flowers like strong light, but they are not tolerant of shade. If the light is insufficient, it will cause the branches and leaves of begonia flowers to grow in vain, and the color of the leaves will become lighter and lighter, and will turn yellow. Matters needing attention in cultivating begonia flowers

Applying fertilizer: Begonia peanuts need more water and fertilizer for a long time. After planting in the upper pot for half a month, the decomposed cake fertilizer water can be applied once, and the light fertilizer water can be applied every 2 ~ 3 days in the later growth period. After the first flower appears, the nitrogen fertilizer should be reduced and the phosphorus and potassium fertilizer should be applied more.

key points of watering: the water of begonia flowers should not only keep high air humidity, but also make the basin soil too wet frequently; Maintain a high air humidity, and often spray water mist around the leaves and flowerpots. Watering should be dry and wet, and the pot soil should not be waterlogged. If the pot soil is too wet for a long time, it will cause rotten roots and even the whole plant will die.

Pruning essentials: Prune the begonia flower once after defoliation and before germination in early spring, and cut off the weak branches, pests and diseases, so as to keep the canopy evacuated, ventilated and transparent. In order to promote the vigorous flowering of plants, the long branches should be cut short to reduce the nutrient consumption of germination, so that the axillary buds can get more nutrients and form more flowering and fruiting branches. Fruiting branches and intermediate branches need not be pruned. During the growth period, the effect will be more significant if the core can be picked in time and the vegetative growth can be restricted at an early stage. The pile landscape of potted plants should be controlled in this way.

replacement of pot soil: Begonia flowers can be replaced with a batch of pond mud or rich soil in the rhizosphere every autumn and winter.

key points of propagation: Begonia flowers are usually propagated by sowing, branching and grafting.

1. Grafting is the main method, and layering and branching can also be used. The sowing method is only used for breeding. Grafting rootstocks mostly use Chinese flowering crabapple or Vitex negundo. Resistant to extensive cultivation and wide adaptability. Only proper irrigation, fertilization and attention to shaping and pruning are needed in cultivation, so that plants can be healthy and flowers can be multiplied.

2. Sowing can be autumn sowing or spring sowing after sand storage. Seedling growth is slow, it takes 5-6 years to blossom, and it often mutates, so it is only used for rootstock cultivation and cross breeding.

most horticultural varieties are propagated by grafting, with Vitex negundo or Malus begoniana seedlings as rootstocks, and branch grafting and bud grafting can be used, while branch grafting and split grafting can be used, and bud grafting can be used for many purposes? Ding? Glyph connection. Many branches are planted before germination in early spring or after defoliation in autumn and winter. Grafting before germination in spring or between July and September in autumn. Propagation by ramets before germination in spring or after defoliation in autumn and winter. Spring layering and root cutting. Before sowing in spring, seeds must be treated with low temperature stratification and germination acceleration for 3 ~ 1 days. After planting seedlings, the soil should always be loose and fertile, and pond mud or rich soil can be cultivated in the rhizosphere every autumn. Prune once in spring, cut off dead and weak branches, keep tree-like evacuation, ventilation and light transmission. Generally, it is planted in multiple rows, but it is also possible to make piles and practice potted plants. The suitable planting period is before germination in early spring or after defoliation in early winter. When the seedlings leave the nursery, it is one of the keys to maintain the complete root system of the seedlings.

pest control: the main pest of begonia flower is begonia rust, so it is necessary to spray bordeaux mixture or fenxiuning in time. Rot disease, spraying Bordeaux mixture or stone sulfur mixture. Aphids can be controlled by cartap or dimethoate. Tetranychus viennensis can be controlled by dicofol. Pruning methods of begonia flowers

Begonia flowering shrubs all have long and short branches, the short branches are flowering branches, and the long branches are vegetative branches. Two weeks after flowering, the long branches can be cut short except for thinning some inner branches and cross branches, and 3~4 buds can be left from the base of the long branches, and the rest short branches can be cut off, which is beneficial to increase the short branches that form flower buds.

make sure the whole plant is ventilated and light-permeable. In addition, when pruning during dormancy, be careful not to cut off the full branches that grew short in the first year. At the same time, excessive use of nitrogen fertilizer should be restrained when fertilizing.
