When transplanting, it is best to bring some soil along, as this will be more beneficial to its growth. However, this water culture method for German iris is rarely used; soil culture is generally used for planting. The specific steps are as follows:

1. When planting German iris, sowing is generally carried out in autumn. The seeds are broadcast in fertile soil, and then you wait for it to grow. If transplanting is needed, it is generally done in spring each year. When transplanting, spacing must be done properly, with 45 cm being optimal.

2. After planting, German iris must be watered properly. There is a lot of rain in summer, so drainage must be done actively to avoid root rot.

3. As for fertilizing, it is done in spring and autumn, and fertilizing just twice is enough. The amount of fertilizer must be controlled well; too much fertilizer is actually harmful to its growth. Generally, bone meal mixed with superphosphate, potassium sulfate and ammonium sulfate is applied.

4. Then pest and disease prevention and control work must also be done actively, with timely detection and treatment.
