Cultivation methods and precautions of bulbous begonia

Farming methods

soil

To grow bulbous begonias, the soil needs to be fertile, loose and breathable, rich in humus, and can be acidic. Generally, you can use garden soil, river sand, and leaf mold. In order to increase the fertility, you can add some base fertilizer.

Light and temperature

Bulbous begonias prefer a warm growing environment, preferably semi-shade, and are more afraid of the scorching heat of summer. The suitable temperature for growth is between 16℃ and 21℃, and it is not cold-resistant. Basically, if the temperature exceeds 30℃, the stems and leaves may wither, and in severe cases, the underground stems may die. A certain temperature must be maintained in winter, and the temperature for wintering should not be lower than 10℃. Bulbous begonias need long-day conditions to bloom well. Sufficient light needs to be maintained in the summer, but care should be taken to avoid direct sunlight in the summer and provide shade in time. The daylight hours are shorter in the winter, so sufficient light needs to be ensured.

Watering and fertilizing

Bulbous begonia likes water and fertilizer, and requires a moist growing environment, but there should be no stagnant water because it is afraid of waterlogging. Watering needs to be reduced during the budding and flowering stages of bulbous begonias. In summer, you need to increase the air humidity by spraying water. In autumn and winter, the bulbous begonia gradually enters a dormant period, so watering should be reduced. Fertilization needs to be applied thinly and frequently. During the growth period, some decomposed thin fertilizer water can be applied every 10 minutes. During the flowering period, some fertilizers need to be applied to promote flowering. Note that no fertilization is required during summer and winter.

Precautions

Reproduction method

The main methods of propagation of bulbous begonia are sowing, cutting and cutting tubers. Seed propagation can be done in spring or autumn, and cuttings are mainly done in late spring and early summer.

Pests and diseases

Bulbous begonias need to be prevented from diseases and pests. The main diseases include root rot and stem rot, and the main pests are thrips, aphids and leaf rollers. It is necessary to improve the growth environment of bulbous begonias and spray pesticides in time.
