Just bought the bulb crabapple, usually in the flowering period of the potted plant, 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 for the plant flower failure, and then pruning and repotting.
Begonia tuberhybrida is more sensitive to light, too strong light, small plants, thick leaves, too weak light, plants slender, leggy.The best light requirement is to bask in the sun in spring and autumn, shade at noon, maintain astigmatism in summer and bask all day in winter.
The most suitable temperature for the growth of Begonia tuberhybrida is 16-25 , which is the most favorable for the growth of plants to ensure a certain temperature difference between day and night.In summer, attention should be paid to shading and cooling, when the temperature exceeds 32 C, the plants are easy to wither and rot.In winter, the curing temperature should be above 10 .
Begonia tuberosa is most afraid of stagnant water and rotten roots. During the spring and autumn growth periods, the soil should be kept slightly wet, that is, the soil surface should be whitened, and the potted soil should be watered thoroughly.In winter, the temperature is low, water should be strictly controlled, in summer, the temperature is high, more ventilation should be made, and water should be sprayed around the plants to increase humidity.
Most of the bulbous crabapples just bought are with flowers, so there is no need to fertilize, and then fertilize after the plant flowers fail.Usually the growth period of half a month to irrigate a balanced nitrogen, phosphorus and potassium fertilizer, before the flowering period to stop applying nitrogen fertilizer, phosphorus and potassium fertilizer.
In the hot and humid season, stem rot and root rot often occur in Begonia tuberhybrida, so in summer, we must control the temperature and watering amount, ventilate more, and spray carbendazim regularly to prevent the occurrence of various diseases and insect pests.
