Begonia is very fond of scattering light and humid environment, and its cold resistance is not strong.
The soil of Begonia spp. should be loose and well drained.
Water frequently during the growing season to keep the basin soil moist.
During the growth period, the compound fertilizer rich in P and K can be applied once a month, or the thin liquid fertilizer can be applied once every two weeks.
At ordinary times, appropriate pruning should be carried out to maintain a beautiful plant posture and good ventilation.
When the room temperature is below 15 C in winter, we must strictly control watering or spray instead of watering. The suitable temperature for growth is 18-21 ℃, which is easy to cause scorched leaves.
In high temperature season, pay attention to the surrounding air humidity, spray 2-3 times a day.
The winter temperature should not be lower than 8 ℃. In winter, the plants should be placed in the sunlight in the shed in the morning and evening, stop fertilization and control water, and wash the leaves once a week with water close to the room temperature.
It can be carried out in early spring, and the mature seeds can be sown in the propagation basin, which is filled with humus soil, kept at about 16 ℃ and a certain humidity, and can take root. When there are 2-3 true leaves in the seedlings, they can be transplanted to the basin.
With the best effect from May to June, the shoots at the top of the plant were selected as cuttings, which were about 10-15 cm long and inserted into the sand bed. Spray the sand bed every day for 2~3 weeks.
&The clustered varieties can also be propagated in individual plants. The root system of the plant with a long basin can be divided into several clusters to avoid damaging the root system, and then they can be planted in the basin separately.
If there are root knot insects that damage the root system, it will affect the absorption of the root system and cause the plant to be short and lose green. Therefore, nematicides such as Clematis can be buried around the root system for control.
In addition, when the air humidity is too high and the ventilation is poor, grey mould is easy to occur, so it is necessary to strengthen the ventilation and use medicine.
