Precautions

Soil: Fertile, loose and breathable, slightly acidic soil rich in humus. Use garden soil plus river sand and humus soil. In order to increase fertility, you can add some base fertilizer. Light temperature: 16℃-21℃ is preferred. If the temperature exceeds 30℃, it will wither. The overwintering temperature should not be lower than 10℃. In summer, it is necessary to maintain sufficient light and timely shade. Water and fertilizer: Water less during the budding and flowering stages. Spray water in summer to increase humidity.

Cultivation methods

Soil

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

Light and temperature

Watering and fertilizing

Bulb crabapple likes water and fertilizer, and the growing environment requires a moist environment, but there should be no stagnant water, because it is afraid of waterlogging. Begonia bulbs need less watering during their budding and flowering stages. In summer, you need to spray water to increase air humidity. In autumn and winter, bulbous begonias gradually enter the dormant period, so watering should be reduced. Fertilizer needs to be applied lightly and frequently. During the growth period, you can apply some decomposed thin fertilizer every 10 seconds. During the flowering period, you need to apply some fertilizer to promote flowering. Note that fertilizing is not required during summer and winter.
