Planting yellow iris
The best period for planting yellow iris is spring or summer, usually from May to November for the plants to bloom in the following summer.
- Plant the yellow iris rhizomes directly in shallow water.
- Simply immerse each yellow iris pot.
- Keep it shallow, since putting it too deep would keep it from flowering. 15 to 20Â inches (40 to 50Â cm) is too deep already.
- Keep sufficient spacing of about 2 to 4 inches (5 to 10 cm) between neighboring plants.
- Go for sunny locations even though this plant tolerates part sun.
