- Water

It is best to water deeply once a week, providing about an inch of water which is roughly equivalent to 0.6 gallons per square yard, depending on the soil type and weather conditions. Increase watering frequency during prolonged dry spells to maintain moisture but always allow the soil to dry out slightly between waterings. Avoid overhead watering to reduce the risk of fungal diseases. During the winter dormant period, reduce watering significantly, but do not allow the rhizomes to completely dry out.
- Light
Tall Bearded Iris, such as 'Cordoba', thrive best in full sun conditions. They require a minimum of six hours of direct sunlight each day to bloom properly. The ideal spot for planting Tall Bearded Iris is in an area that receives unfiltered sunlight throughout the day, ensuring vibrant blooms and healthy growth.
- Temperature
Tall Bearded Iris 'Cordoba' flourishes in areas with a temperate climate. They can survive winter temperatures as low as 20°F and summer temperatures up to 90°F. However, the ideal growing temperature is between 55°F and 75°F. It is essential to ensure good drainage to prevent rhizomes from rotting in cold, wet soil.
- Pruning
Pruning Tall Bearded Iris 'Cordoba' includes removing spent flower stalks after blooms have faded and cutting back the leaves to a height of about 6 inches in the fall. This helps promote healthy growth and prevents disease. Pruning should be performed annually, and the best time for cutting back foliage is after the first hard frost in autumn.
- Cleaning

- Life cycle
Iris 'Cordoba' (Tall Bearded Iris) begins its life cycle as a rhizome, which, when planted in soil, will sprout roots and green shoots. As the plant matures in the first season, it develops long, sword-like leaves and establishes a strong root system. In the following growing season, the Tall Bearded Iris produces tall stems that bear large, ornate flowers, usually blooming in late spring to early summer. After flowering, the plant enters a period of dormancy during the hotter months, wherein the leaves may die back and the plant conserves energy. In the autumn, the plant may exhibit new growth in preparation for the winter, but in cold climates, the foliage will die back and the rhizome will remain dormant underground. Each year the cycle repeats, with the rhizome producing more shoots and possibly dividing, which can be separated to propagate new plants.
- Propogation
Propogation time
Late Summer-Early Fall
The Iris 'Cordoba' (TB), often referred to as Tall Bearded Iris, is most commonly propagated by division of its rhizomes. The best time to do this is late summer, after the blooming period has ended and the plant is entering dormancy. To propagate, you carefully dig up the clumps of iris and gently separate the rhizomes—ensuring each section has at least one fan of leaves. Trim the leaves to about a third of their height, usually 4 to 6 inches (10 to 15 centimeters), and trim the roots to about the same length to stimulate fresh growth. The new divisions can then be replanted in well-drained soil, with the top of the rhizome slightly exposed to the air. This encourages the plant to settle well and helps to avoid rot or disease that can come with excessive moisture.
