1. Soil

German iris likes relatively loose soil conditions, so it is recommended to use sandy loam for breeding. It does not require high pH of soil, but it grows best in weakly alkaline soil. Conditional flower friends can use lime powder to increase the pH of the soil to 7.0-7.2, which can make it grow faster and better

2. Moisture

During the growth period, it is necessary to provide sufficient water for Iris germanica to meet its growth and development needs; After flowering, the frequency of watering can be controlled. After the rain, it is necessary to carefully check whether there is rainwater residue in the soil. If so, it should be removed in time to avoid waterlogging

3. Fertilization

It needs sufficient nutrients during the growth period, so it needs topdressing once. Fertilizer should be applied thinly and frequently to avoid damaging its roots
