The requirement of ditanghua on soil is not strict, and the growth trend of fertile and loose sandy loam is the best. It is necessary to keep the soil drainage good, soft and non alkaline.
In general, ditanghua does not need more water, but the temperature is too high in summer and the water evaporates too fast. Therefore, it is necessary to increase the amount of water to prevent the basin soil from being too dry.
Ditanghua likes warm and humid environment, so it's necessary to enter the indoor culture for overwintering in winter.
The potted flower needs to be watered in the afternoon, but not too much. In the growth period of the flower, according to the growth situation of the plant, the liquid fertilizer should be applied 1-2 times.
When it is found that there are retreating branches (branches gradually wither from top to bottom), it is necessary to cut off the dead branches immediately, otherwise once it spreads to the root, it will lead to the death of the whole plant.
After the leaves fall, there will be dead branches. At this time, more pruning is needed.
Leave 50cm high after the flowering of the Begonia, and then cut off the upper branches to promote the underground buds to sprout.
If you want to have more branches, leave only about 7cm, and then cut off the rest.
In cold areas, such as the north of the Yangtze River Basin, potted plants need to be changed once every three years or so, and the old and the weak branches need to be renewed in combination with root cultivation and plant division.
