The bulbous Begonia just bought is usually a potted plant in the flowering period. Do not change the pot, otherwise it will affect the growth and flowering of the plant. If you want to change the pot, you can trim and change the pot after the plant fails p>
2、 Astigmatism
Bulbous Begonia is sensitive to light. The light is too strong, the plant is small, the leaves are thick, the light is too weak, and the plant is slender and long. The best lighting requirements are sun exposure in the morning and evening of spring and autumn, sun shading at noon, astigmatism maintenance in summer and sun exposure all day in winter p>
3、 Like warmth
The most suitable temperature for the growth of bulbous Begonia is 16-25 ℃, ensuring a certain temperature difference between day and night, which is most beneficial to the growth of plants.

4、 Less watering
Bulbous Begonia is most afraid of stagnant water and rotten roots. It should keep the soil slightly wet for a long time in spring and autumn, that is, watch the soil surface turn white and carry the basin soil to become light and water permeable. If the temperature is low in winter, strictly control the water. If the temperature is high in summer, be more ventilated and spray water around the plant frequently to humidify p>
5、 Frequent fertilization
Most of the bulbous begonias just bought are with flowers, so there is no need to apply fertilizer until the plants fail. Generally, the fertilizer and water with balanced nitrogen, phosphorus and potassium are watered once every half a month during the growth period. Nitrogen fertilizer is stopped before flowering and phosphorus and potassium fertilizer is used instead p>
6、 Diseases and insect pests
Stem rot and root rot often occur in bulbous Begonia in hot and humid seasons. Therefore, in summer, we must control the temperature and watering amount, provide more ventilation and regularly spray carbendazim to prevent the occurrence of various diseases and pests p>
