What is the culture method of Begonia bulb?

Bulbous begonia culture method, bulbous begonia 15-25 cm high, succulent stem, underground tubers. The flower is rich in color, the flower stem reaches 5 to 10 cm, and the flower type has single and double petals, suitable for potted plants or hanging pots. The sex likes cold and cool, the cultivation is not easy, the florescence is from spring to summer.

The basin soil of Malus bulbifera is required to be loose and permeable, rich in organic matter and strong in water and fertility, which can be mixed with 4 parts of rotten leaf soil, 3 parts of loam, 1 part of perlite and 1 part of mature organic fertilizer. Cultivation place 60% ~ 70% sunshine is the best, good ventilation, avoid high temperature and humidity, otherwise the stems and leaves are easy to rot. Because it belongs to short-day flowering, long-day dormant plants, when the light time is insufficient, the leaves will be relatively thin, when the light is too strong, the plants are short, the leaves are thick and curled up, and the flowers contract and expand insufficiently.

It should be shaded in late spring and early summer to avoid leaf burns caused by strong light. It takes more than 13 hours of light to bloom. If the plant has grown to a considerable height, it can be illuminated for 3 hours from 10:00 to 1 am in the evening to promote flower bud differentiation. Topdressing can be used with three elements of nitrogen, phosphorus and potassium, once a month. After flowering, wait for the underground part to be withered and yellow, dig up the bulbs, store them in sawdust or river sand after drying, and plant them again in the following spring. The suitable temperature for growth is 18-22 ℃.

The maintenance of Begonia bulbosa should do a good job in the regulation of sunlight and temperature, reasonable fertilization and water management, and provide loose and fertile culture soil. Begonia bulb prefers a warm and moist natural environment. When the temperature is 12-26 ℃, it will cause plant dwarfing, leaf thickening and curling under strong light, and flower bud shedding when the temperature exceeds 30 ℃. The above is the introduction of the culture method of Begonia bulbosa.

Culture methods of Begonia bulbosa: light and temperature

Temperature and light bulb crabapple sex like warm, relatively humid growth environment, do not like the summer heat, but also can not stand the winter cold, semi-overcast is the best. The most suitable temperature for the growth of Begonia bulb is 16 ℃ ~ 21 ℃. If the temperature is above 30 ℃, the flower stems, branches and leaves are very likely to wither, and some even face the death of underground stems. The lowest temperature of breeding should not be less than 10 ℃, and you should pay attention to keeping warm when overwintering. In addition, the bulb begonia also loves light, good long sunshine is the basic guarantee of flowering, summer should not only ensure sufficient light but also pay attention to the strong direct sunlight. Pay more attention to sufficient sunshine in winter when there is a lack of sunshine.

Soil

Planting bulbous begonia soil should also pay attention to the need for nutrient-rich, loose, breathable, rich in humus, slightly acidic soil is also possible. In general, we can add river sand to the garden soil, or configure rotten leaf soil. In addition, adding some base fertilizer to the basin can increase the fertility.

Watering

Begonia bulb likes the moist growth environment, but is afraid of waterlogging, so it is best not to have stagnant water. The dry weather in summer should increase the air humidity by spraying water, reduce watering in autumn and winter in dormant period, and reduce watering in the budding and flowering period of Begonia bulb.

Fertilizer application

Begonia bulb relatively like water and fertilizer, fertilization pay attention to thin application of fertilizer. During the plant growing period, some mature and thin fertilizer and water can be applied every ten days. During the flowering period, some fertilizers are needed to promote flowering. Special attention should be paid not to fertilizing in winter and summer.

The Culture method of Begonia bulb Begonia needs dormancy in winter. They keep blooming during the growing season. Its flowers are very large, its heart is very high, and its petals are orderly. The plant grows vigorously. The price is a little higher. Bulbous begonia growth period should pay attention to the following points: 1, watering: do not directly irrigate the soil above the bulb. You can press the canal on the edge of the basin with your fingers. Pour the water into the canal carefully. If it is hot, avoid being caught in the rain. 2. Lighting: direct light before 11:00 can be accepted outdoors. Shade the rest of the time. No summer exposure. The room should be placed on the windowsill and the light should be adjusted according to the environment. 3. Environment and temperature: the temperature difference between day and night is very helpful to the growth of Begonia bulb. Unlike tulips, daffodils and buttercups, begonia flowers don't need to be cool. They keep blooming from spring to summer to autumn. It's very beautiful. In addition, they are perennial, blooming year after year. Pay attention to planting (planting) shallow points, see that the new buds are pink. Very tender, as fragile as cream, don't touch it. And then you can add dirt. Its bulbs are different from cyclamen. There are many roots on the top of the bulb crabapple flower. Therefore, it must be buried deep in the soil 5cm. Fortunately, it doesn't require depth like lilies. So it's very suitable for potted plants.
