Rieger Begonia likes slightly acidic soil, and the planting soil mixed with garden soil and pine needle soil is better, which meets the requirements of slightly acidic and takes into account ventilation and ventilation.If there is no pine needle soil, dilute ferrous sulfate can be added to the garden soil to adjust the acidity and alkalinity of the soil.
When you buy it back, you should give it a comfortable environment, good ventilation, preferably 18-25 C room temperature and mild light to ensure its growth and development.Winter should be spent at home, and the temperature should not be lower than 5 degrees Celsius.In summer, appropriate shading should be given, and the temperature should not exceed 30 C.

When watering, a small amount of potash fertilizer can be added to the water once every half a month to promote its growth.After the flowering period, compound fertilizer can be applied once to supplement nutrition and prepare for the next flowering.Fertilization is not needed at other times, and excessive fertilization may lead to root damage, which is not worth the loss.
Proper pruning should be carried out after the flowering period to reduce its consumption and make it safe to spend the summer.Cut off redundant and damaged branches, and apply some sterilizing drugs at the cut to disinfect, so as to prevent the problem of branch decay.
