How to grow German iris

1. Soil

German iris prefers relatively loose soil conditions, so sandy loam is recommended for cultivation. It does not have high soil pH requirements, but grows best in slightly alkaline soil. Flower lovers who have the conditions can use lime powder to raise the pH of the soil to 7.0-7.2, which will allow it to grow faster and better.

2. Moisture

During the growing season, German iris needs to be provided with sufficient water to meet its growth and development needs; after flowering, the frequency of watering can be controlled. After the rain, you need to carefully check whether there is any rainwater left in the soil. If there is, it should be removed in time to avoid waterlogging.

3. Fertilization

It needs sufficient nutrients during the growth period, so top dressing is required. When applying fertilizer, be careful to apply it in small amounts and frequently to avoid damaging its root system.
