(1) soil: for the soil, the acid or neutral soil is the best, and its composition is the mixture of river sand, rotten leaf soil and snake sawdust. The nutrient soil composed of rotten leaf soil, field soil and sand soil in the proportion of 5:3:2 can also be used. Be careful not to use saline alkali soil and clayey soil, otherwise it will lead to poor growth.
(2) temperature: its best growth temperature is between 18 ℃ and 20 ℃, because it is relatively cold resistant, so long as the room temperature is not less than 10 ℃, it can be placed outdoors.
(3) sunshine: it is a kind of plant that likes sunshine. It is suitable to be put in sunny place with good light and keep good ventilation. If you put it in a cool, dark place for a long time, it will hinder growth, so make sure it has enough light time.
(4) watering: water as little as possible during the germination period, and increase the amount of watering in the growth period, just two times a day. When watering, we should pay attention to the technique, don't drench the water to the stem and leaf, we should slowly pour along the edge of the flowerpot, otherwise the water in the stem and leaf is easy to rot.
(5) fertilization: it does not need fertilization at ordinary times, but it will lose a lot of nutrients when Begonia leaves in autumn, so it is necessary to apply a large amount of fertilizer to supplement nutrients. In early spring, we need to apply fertilizer once, and we need to pour water once, which can let fertilizer fully penetrate into the soil.
Before it sprouts in spring after falling leaves, it needs to be pruned carefully to cut off dead branches, diseased branches and thin branches, so as to increase its transparency and ventilation. If you want to increase the number of bracts, you need to cut the long branches short, so that other axillary buds can get more nutrition, but also need to remove it in time, so that the nutrition is not scattered.
