Where and how to plant?
There are certain planting rules that you are advised to follow. For planting, it is necessary that the flowerpot is 1/3 filled with drainage material, on top of which there should be a 2-3 centimeter layer of charcoal. Thanks to this, the roots do not rot.
After the begonia, along with a lump of earth, is placed in the pot, the rest of the space must be filled with soil and watered. Planting is carried out in March, after the daylight hours become longer. And before that, tuberous begonias germinate in boxes, they do not need to be buried in the substrate. They should be located in a bright place with an air humidity of 60-70% and a temperature of 16-18 ° C.
Every year in the spring, the plant must be transplanted into a pot, which should be 2 cm wider than the previous one.
Important! Bush begonia is one of the easiest to grow. The plant has a luxurious shape due to the fact that in one bush there can be up to 5 pieces of stems.
Lighting and location
The plant feels better in well-lit places, but so that direct sunlight does not fall on it. For this, window sills of windows facing west and east are suitable. In the fresh air, they are planted in a place where diffused light is observed. Bush begonia does not tolerate when the direction of light changes, so it is not advised to turn it.
You can buy soil for a flower in a store or prepare it yourself. Pour a small layer of sand at the bottom, then fill the pot halfway with leafy soil and add black soil and peat in equal proportions.
If the soil is prepared correctly, then the bush begonia will grow well and bloom for a long time. The trunk will become strong and the leaves will be healthy and juicy.
Proper grooming of begonia consists of:

- top dressing;
- planting and pruning.
The main thing in caring for this plant is uniform watering. The soil in the pot should not be wet, but slightly damp.

This should be done less frequently in winter. The plant needs feeding 2 times a week with any ready-made mineral fertilizers intended for flowering plants. It is best if they are in liquid form.
Humidity and temperature
Bushy begonias need moist air, which can be organized by spraying the area around this plant.
Important! When spraying, do not allow water to come into contact with flowers and leaves. This can lead to their decay and loss of decorativeness.
To create optimal humidity, it is enough to place a flowerpot in a pallet, with expanded clay poured into it, and pour water there. It is only necessary that the bottom of the pot does not stand in it. On hot summer days, the windows, on the windowsill of which there is a bush begonia, must be protected with paper.
The flower will shed its buds in case of sudden temperature changes and drafts. The best temperature for growing this plant is considered to be 20-25 ° C, in winter it is not less than 15 ° C. In winter, it begins a dormant period, growth stops, and for several weeks it does not bloom at all.

A newly transplanted flower is not recommended to be immediately exposed to the sun. To form a new crown, it needs to be pruned a little. The rejuvenation procedure is necessary because the lower part of the stem of an adult plant becomes bare. To do this, the tops of the bare stems are cut and rooted.
