The latest Culture method of Begonia Flower

Begonia flower is endemic to China. Growing in the plains and mountains of 50 to 2000 meters above sea level, it can be artificially introduced and cultivated as deciduous small trees. Begonia like light, cold resistance, avoid waterlogging, avoid too wet air, more resistant to drought, soil quality and water requirements are not strict, the most suitable to be born in fertile, loose and well-drained sandy loam.

Reproduction method

Begonia flowers are commonly used for sowing, ramet and grafting propagation. Sowing can be sowed in autumn or in spring after sand storage, and the seedlings grow slowly and blossom after 5 to 6 years, and often produce variation, so it is only used for rootstock cultivation and cross breeding.

Horticultural varieties are often propagated by grafting, with bauhinia or begonia seedlings as rootstocks, branch grafting, bud grafting, branch grafting, split grafting, and bud grafting. Grafting before sprouting in spring or between July and September in autumn. Propagate separately before sprouting in spring or after defoliation in autumn and winter. Spring striping and root insertion. The seeds must be treated by low temperature stratification for 30-100 days before sowing in spring. After seedlings are planted, the soil should be kept loose and fertile, and pond mud or fertile soil can be cultivated in the rhizosphere every autumn. Carry on a pruning in spring, cut off the withered and weak branches, keep the tree shape evacuated, ventilated and transparent.

Generally multi-row ground planting, but you can also make pile scenery to implement potted plants. The suitable planting period is before sprouting in early spring or after defoliation in early winter. when the seedling comes out of the nursery, keeping the intact root system of the seedling is one of the keys to the survival of planting.

Cultivation techniques

Generally, large seedlings should be planted with soil balls, and small seedlings should stay in the lodging soil according to the situation. After the seedlings are planted, the tending management should be strengthened, and the soil should be kept loose and fertile. A batch of pond mud or fertile soil can be cultivated in the rhizosphere every autumn and winter.

A pruning was carried out from the defoliation to the sprouting in early spring to cut off the weak branches, disease and insect branches in order to keep the crown open, ventilated and transparent. In order to promote the vigorous flowering of the plant, it is necessary to truncate the overgrown branches to reduce the nutrient consumption of germination, so that the remaining axillary buds can get more nutrients and form more flowering and fruiting branches. Fruit branches and middle branches need not be pruned. During the growth period, if the heart can be removed in time and the vegetative growth is restricted in the early stage, the effect will be more significant. The pile scenery of potted plants should be controlled in this way.

In early July, potted crabapple trees were moved to shady places to cool down, reduce light and control watering. Watering should be slowly reduced to make the leaves of the plant yellow and fall off on its own, so as to promote its dormancy. Then continue a small amount of watering in order to maintain life and not sprout new buds. In this way, after a dormant period of 35-45 days, the plant was placed in full light, watered and fertilized with liquid fertilizer to awaken and sprout new buds (leaf buds and flower buds). After another 5-7 days, you can see the bright crabapple flowers.

In addition, we can also make use of the temperature-sensitive habit of its bud to use the method of heating to promote flowering in the middle of winter, move the potted begonia pile scene into the sunny part of the greenhouse, pour water thoroughly, add liquid fertilizer, and then spray water on the plant branches every day to keep the room temperature at 20-25 ℃. After 30-40 days, it can also blossom, which can be used for New Year's Day or Spring Festival decoration. Water raises big branches and cut flowers, which can also be promoted in the greenhouse. It can be raised in batches throughout the winter and can be used whenever it is opened.
