  • water dropWater

    The Tall Bearded Iris 'Titan's Glory' should be watered deeply and infrequently to encourage strong root growth; this typically means providing about an inch of water weekly. During its active growth in spring and early summer, ensure the soil is consistently moist but not waterlogged. As a rule of thumb, adding approximately half a gallon per square foot every week should suffice. Reduce watering after blooming, as the plant prefers drier conditions especially during its dormant season in late summer and fall. Overwatering can lead to rot, so it is crucial to allow the soil to dry out somewhat between watering sessions.

  • sunLight

    Tall Bearded Iris 'Titan's Glory' thrives best in full sun conditions, with at least six hours of direct sunlight each day. Planting in a spot that receives morning light is ideal, as it dries dew quickly and helps prevent disease. If you live in a particularly hot climate, a location with afternoon shade can help protect the plant from intense heat, but overall, more sun equals better growth and blooming.

  • thermometerTemperature

    The Tall Bearded Iris 'Titan's Glory' is hardy and can tolerate temperatures as low as -30°F and as high as 90°F. However, it grows best in temperate conditions with an ideal temperature range of 55°F to 75°F. Extremes of heat or cold outside the mentioned range may affect the plant's health and blooming ability, so it's best to provide some protection during unusually severe weather.

  • scissorsPruning

    Prune Tall Bearded Iris 'Titan's Glory' by removing spent flower stems down to the base after blooming to promote rhizome health. Cut back the leaves to about six inches in a fan shape in late summer to tidy the plant and allow for new growth. Pruning is also necessary to remove any damaged or diseased foliage, which should be done as soon as the issue is noticed. The best time for major clean-up pruning is early spring or just after flowering.

  • bambooSoil

    Tall bearded irises like 'Titan's Glory' prefer well-draining, fertile loam with a slightly acidic to neutral pH of 6.8 to 7.0. The best soil mix should incorporate organic matter such as compost or well-rotted manure to provide nutrients and improve soil structure.

  • plantRepotting

    Tall bearded irises, including 'Titan's Glory', typically do not require frequent repotting and can be left undisturbed for several years. Dividing and repotting are usually done every 3 to 5 years to prevent overcrowding and maintain vigor.

  • circleLife cycle

    Iris 'Titan's Glory', commonly known as Tall Bearded Iris, begins its life cycle when the rhizomes (underground stems) are planted in late summer to early fall in well-draining soil. The plant establishes roots and foliage before going dormant in winter. In the following spring, new growth emerges, and the iris forms tall stems that bear large, showy purple flowers, typically around late spring to early summer. After blooming, the flowers fade, and the plant redirects energy to the rhizomes to store for the next season. The foliage continues to photosynthesize and contribute to the energy reserves until it withers in late autumn. Division of rhizomes is recommended every 3 to 5 years to prevent overcrowding and to encourage vigorous blooms, thus perpetuating the life cycle.

      Late Summer to Early Fall

    • The most popular method for propagating Iris 'Titan's Glory', which is a Tall Bearded Iris, is through division of its rhizomes. This is ideally done after the blooming period, which typically is late summer to early fall. To propagate by division, gardeners should carefully dig up the clumps of the iris and gently separate the rhizomes, ensuring each division has at least one fan of leaves and a portion of the roots. Pruning the leaves into a fan shape, approximately 4 to 6 inches (10 to 15 centimeters) in height, can help reduce water loss and give the plant a better chance to establish. The divisions can then be replanted immediately, about 12 to 24 inches (30 to 60 centimeters) apart, in a well-draining soil with the top of the rhizome slightly exposed to the air. This method of propagation ensures genetic consistency and can rejuvenate older plants that have become less vigorous over time.
