Potted xiandanhua usually leaves the house in April, when it has already entered the growth period. Spring and autumn are the vigorous growth periods of xiandanhua. During this period, it is necessary to ensure sufficient water and fertilizer. If fertilizer is applied, a small amount of compound fertilizer should be applied every half a month.
When watering, first of all, it is necessary to ensure that the basin soil is wet. In principle, it is necessary to see that the basin soil is wet when it is dry, and the basin soil is fully watered when it is dry. Pay attention not to accumulate water. In spring, watering can be done every three days, autumn is to control the amount of watering properly, which can make the branches grow more robust.
Because of its unique climate characteristics, summer will have different performance when watering. First of all, the evaporation is fast in the high temperature of summer, so it needs to be watered every day. In order to maintain high air humidity, it also needs to regularly spray water to the plants and the ground. However, when it is rainy in summer, do not water it. If it rains accidentally, it needs to drain water in time to prevent rotten roots. When watering, if possible, choose to use rain water or snow water, or some ferrous sulfate solution, so as to avoid the soil is slightly alkaline, which is harmful to the growth. You can also often pour some alum fertilizer water to xiandanhua to keep the leaves green.
In winter, because of the low temperature, the growth of xiandanhua has been very slow. At this time, we should control the amount of water to avoid watering but not being absorbed by plants, resulting in water accumulation.
