5. Fertilization

Begonia is applied dilute liquid fertilizer every 10 days in the growing season, and less or no fertilizer is applied in summer and winter when the growth is slow, so as to avoid rot due to tender stems and leaves and weakening heat and cold resistance.

VI. Pest control

Common diseases include leaf spot and bacterial diseases, which should be controlled by topiramate, chlorothalonil and Jinggangmycin. Pests are mainly pests that harm leaves and stems, such as slugs, thrips, leaf miners and so on.

7. Trimming
