How to Care for the Plant

Water
Newly planted bearded irises need watering to help them establish. After that, they rarely need to be watered except in extremely hot, dry summers. It is always better to underwater than overwater, as too much water can induce rot.
Pruning
Cut back the flower stems to their base after flowering.
Fertilizer
Feed with a balanced or high potash general granular plant food in early spring and then again after flowering. Avoid using high nitrogen feeds as this can encourages rot problems.

Sunlight
Dutch iris perform best when they are planted in full sun, but they will also grow in part shade.
Soil
Dutch iris require well-drained soil. If you want to encourage the bulbs to perennialize, choose a planting location where the soil will be hot and dry during the summer months.
Temperature
All bulbs love good air circulation. Store them in a cool, dry place with low humidity, away from heat, frost and strong sunlight at about 50°F to 70°F. Never put flower bulbs in the freezer!
