Bearded Iris Iris 'Celebration Song' (TB)

Water

The Tall Bearded Iris, commonly referred to as Iris 'Celebration Song', prefers to be watered deeply and infrequently to encourage its deep-rooted system. During the active growth season in spring and early summer, water the iris once a week with about a gallon of water per plant, ensuring consistent soil moisture. However, it is important to allow the soil to dry out slightly between waterings to prevent rot. Reduce watering after the blooming period as the plant enters dormancy; during this time, watering every two weeks may suffice. Pay special attention to container-grown irises, which may require more frequent watering due to faster drying soil.

Light

The Iris 'Celebration Song' thrives best in full sun, receiving at least six hours of direct sunlight each day. The ideal spot for this plant is in an area that gets unobstructed morning sunlight and partial shade during the hottest part of the afternoon to protect the blooms from scorching. However, too much shade can lead to poor flowering, so choosing a spot with ample sunlight is essential for vibrant blooms.

Temperature

Tall Bearded Irises such as the 'Celebration Song' perform well in a wide range of temperatures, withstanding lows down to approximately 10 degrees Fahrenheit and tolerating highs well into the 90s Fahrenheit. The ideal growing temperature for these irises is between 55 and 75 degrees Fahrenheit, as this range encourages optimal growth and flowering. In climates where temperatures fall below 10 degrees Fahrenheit, providing winter mulch can help protect the rhizomes from freezing.

Pruning

Regular pruning is not necessary for the Tall Bearded Iris 'Celebration Song', but it is beneficial to remove the spent flower stems after blooming to maintain a tidy appearance and redirect energy back to the rhizome. In late fall, trim back foliage to about 6 inches to prevent overwintering pests and diseases. Additionally, every 3 to 5 years, prune by dividing the rhizomes in late summer to rejuvenate the plant and encourage vigorous growth.

Cleaning

As needed

Soil

Tall Bearded Iris 'Celebration Song' prefers well-draining soil enriched with organic matter, with a pH between 6.8 and 7.0. A mixture of sandy loam, compost, and a low concentration of bone meal aids in providing the necessary nutrients and drainage.

Repotting

Tall Bearded Irises such as 'Celebration Song' do not require frequent repotting; they should be divided and transplanted every 3 to 5 years to avoid overcrowding and to rejuvenate growth.

Humidity & Misting

Tall Bearded Iris 'Celebration Song' tolerates a wide range of humidity levels and typically thrives in the humidity found in outdoor garden environments; they do not require high humidity.

Suitable locations

• Indoor

  Ensure bright light, cool temps, and good air circulation.

• Outdoor

  Plant in full sun, well-drained soil; water sparingly.

• Hardiness zone

  3-9 USDA

Life cycle

The 'Celebration Song' iris, a variety of Tall Bearded (TB) iris, begins its life cycle when the seeds are sown or rhizomes are planted in late summer to early fall. The plant enters a vegetative stage, developing long, sword-like leaves and establishing an extensive root system. As spring approaches, it enters the reproductive stage, with flower stalks elongating and buds forming, which then bloom into the plant's distinct, colorful flowers. After pollination, possibly involving bees or other insects, the flowers fade and seed pods may form if the flowers were successfully pollinated. The plant then enters a period of dormancy, especially in colder climates, where the foliage dies back, and the rhizome rests underground. The following growing season, the cycle repeats, with the rhizome sending up new growth and the plant continuing to mature, often spreading to form larger clumps.

Propogation

• Propogation time

  Late Summer to Early Fall

• Propogation: The most popular method of propagation for the Tall Bearded Iris 'Celebration Song' is by dividing its rhizomes. This is typically done after the flowering season has concluded and the plant has gone dormant, which is often in late summer to early fall. To propagate, dig up the iris clump carefully, and using a sharp knife, separate the rhizomes ensuring each division has at least one fan of leaves and a portion of the roots. Trim the leaves to a third of their height to reduce water loss and replant the divisions about 12 to 24 inches apart (30 to 60 cm), with the top of the rhizome slightly exposed to the air. Water the new plantings well to help establish them. This method not only helps to rejuvenate and increase your stock of irises but also encourages better blooming in the following seasons.
