Bulbous Begonia likes warm and humid environment, but bulbous Begonia is not suitable for growing in too hot environment. We should pay attention to this when planting bulbous Begonia. So when summer comes, we can spray water around the Begonia to cool down properly, to avoid the leaves and flowers from withering and falling due to the high temperature.
Although bulbous Begonia likes humid environment, it can't be watered too much at one time. Water accumulation will affect the growth of bulbous Begonia and may cause the reproduction of bacteria, so we should do a good job in drainage. In particular, it should be noted that it is not suitable to irrigate too much water at the stage of germination or about to bloom of Begonia bulbous, during which the amount of water should be reduced. In winter, we should also reduce the watering amount of Begonia.
Bulbous Begonia is a kind of plant which needs a lot of fertilizer. It likes a little acid soil.
In the Begonia in the growth period, the three elements of nitrogen, phosphorus and potassium fertilizer demand is the same, to apply evenly.
When the Begonia is about to enter the flowering stage, it is necessary to increase the amount of P and K fertilizer appropriately, so as to promote flowering and make the flower more delicate. In this period, the fertilizer can be applied every 3-4 days, and the content of fertilizer can also be increased moderately. When applying fertilizer at ordinary times, we can follow the principle of applying more thin fertilizer, which is conducive to the absorption of fertilizer by plants. It should be noted that there is no need to fertilize Begonia in summer and winter.
