Bearded irises are easy to grow. They are also tolerant of strong alkalinity and mild acidity. We send a four page leaflet giving detailed cultural information with each order. The more sun they get, the better they will grow and flower. Give good drainage.
Bad drainage leads to rot.
Add grit to your soil before planting if you are not sure, or use beds raised above surrounding paths so that moisture drains away. Do not plant with the rhizome exposed - this will not be deep enough for the plant to be properly anchored. The plant will push itself to the surface when it has established new roots. This leads to soft lush growth and few flowers - in extreme cases it can promote rotting by impairing drainage. Avoid using high nitrogen fertilizers.
