Soil: Iris germanica prefers relatively loose, slightly alkaline soil, so sandy loam with a pH between 7.0-7.2 is recommended for growing it. Water: It needs plenty of water during the growing period; after flowering, reduce watering and drain promptly after rain. Fertilizing: It needs plenty of nutrients during the growing period, so one round of topdressing is needed.

1. Soil

Iris germanica prefers relatively loose soil conditions, so sandy loam is recommended for growing it. It is not demanding about soil pH, but it grows best in slightly alkaline soil. If conditions allow, growers can use lime powder to raise the soil pH to 7.0-7.2, which will help it grow faster and better.

2. Water

During the growing period, Iris germanica needs to be given plenty of water to meet its growth and development needs; after flowering, the watering frequency can be reduced. After rain, carefully check whether rainwater remains in the soil, and if so, drain it promptly to avoid waterlogging damage.

3. Fertilizing

It needs plenty of nutrients during the growing period, so one round of topdressing is needed. When fertilizing, apply light fertilizer frequently to avoid damaging its root system.
