tall bearded iris

Tall bearded iris should be watered once a week and given an inch of water each time. It’s important to water these plants deeply and slowly so that the root system can absorb enough of the water. It’s best to water them in the morning or early afternoon so their foliage is dry before the overnight temperatures begin to drop. Additionally, if the temperatures are especially hot, you may need to give them a bit more water to help them get through the day.

Tall bearded irises require full sun for around 6 to 8 hours a day to grow and bloom properly. They also benefit from afternoon light or filtered sunlight when temperatures become extremely high. Additionally, tall bearded irises prefer morning sun, with temperatures gradually increasing throughout the day and then shrinking in the evening. They should be kept away from harsh direct sunlight in the middle of the day. The more sun they get the more likely they are to bloom the following summer, although too much sun can have a negative impact on their health.

Tall bearded iris should be pruned annually, usually in late summer. About 2-thirds of the foliage should be removed with pruners or other cutting tools. Cut all dead foliage and flower stalks, and trim back any long, weak stalks. This helps to promote new growth and healthy plants. When pruning, make sure to keep the base of the plant undamaged, as this is where next year’s new foliage will come from.
