How to care for the newly bought bulbous begonia

1. Avoid changing pots

The newly purchased bulbous begonias are usually potted plants 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 wait until the flowers of the plant fade, and then prune and change the pot.

2. Astigmatism

Bulbous begonia is sensitive to light. If the light is too strong, the plant will be small and have thick leaves. If the light is too weak, the plant will be thin and grow too tall. The best lighting requirements are sun exposure in the morning and evening in spring and autumn, shade at noon, diffuse light maintenance in summer, and all-day sun exposure in winter.

3. Like warmth

The most suitable growth temperature for bulbous begonias is 16-25℃. Ensuring a certain temperature difference between day and night is most beneficial to the growth of the plant. Pay attention to shading and cooling in summer. If the temperature exceeds 32℃, the plants will easily wither and rot. In winter, ensure the maintenance temperature is above 10℃.

4. Water less

Bulbous begonias are most afraid of waterlogging and root rot. During the growing seasons in spring and autumn, the soil should be kept slightly moist. That is, when the soil surface turns white and the soil in the pot becomes light, water it thoroughly. In winter, the temperature is low, so water must be strictly controlled. In summer, the temperature is high, so more ventilation is required and water should be sprayed around the plants frequently to increase humidity.

5. Fertilize frequently

Most of the newly purchased bulbous begonias still have flowers, so there is no need to fertilize them. Wait until the flowers fade before applying fertilizer. Usually, water the plant with balanced nitrogen, phosphorus and potassium fertilizer once every half a month during the growing season. Stop applying nitrogen fertilizer before flowering and use phosphorus and potassium fertilizer instead.

6. Pests and diseases

In hot and humid seasons, bulbous begonias often suffer from stem rot and root rot, so in summer, you must control the temperature and amount of watering, ventilate more, and spray carbendazim regularly to prevent the occurrence of various diseases and pests.
