This typically means watering once every week to two weeks, depending on weather conditions and soil drainage. Approximately one inch of water per week, including rainfall, is adequate. During dry spells or in particularly hot climates, you might need to water every five to seven days. It's essential to avoid overwatering, as standing water can cause rhizome rot in bearded irises.

  • sunLight

    Tall Bearded Irises, such as Iris 'Pascoe', thrive in full sun conditions where they receive at least six hours of direct sunlight daily. They can tolerate partial shade, but flowering may be reduced in less than optimal light.

    Pruning Tall Bearded Iris 'Pascoe' involves removing spent flower stems down to the base after blooming to prevent seed formation and tidy the plant. In late summer or early fall, trim the foliage into a fan shape about 6 inches high to prepare for winter and encourage healthy new growth in the spring. Prune damaged or diseased leaves as needed throughout the growing season to maintain plant health.

  • circleLife cycle

    Iris 'Pascoe,' a tall bearded iris, begins its cycle when its seeds are sown, typically after a period of stratification to break dormancy. Germination follows, and the seedling's roots and shoots start to develop. As it matures, the plant forms a rhizome, which is an underground stem that stores energy and produces fans of long, blade-like leaves. Once established, this rhizome can produce new shoots, contributing to the plant's clonal spread. The iris reaches flowering maturity after a few seasons, producing showy blossoms that are typically purple or lavender, but can vary in color, used for reproduction through both self-pollination and cross-pollination by insects. After blooming in late spring to early summer, seed pods may form and, once matured, they open up to release seeds, thus beginning a new cycle.

      Late summer

    • The most popular method for propagating the Iris 'Pascoe', a Tall Bearded Iris, is through division. This is typically done in late summer after the blooming has finished. The rhizomes of the iris are lifted from the ground carefully to avoid causing too much damage. Using a sharp knife, the rhizomes are divided into sections, ensuring each piece has at least one fan of leaves and a portion of the roots. The leaves are then trimmed back to about one-third of their height, which facilitates easier establishment and reduces moisture loss. These divisions are replanted promptly, usually around 12 to 24 inches apart, setting them so the tops of the rhizomes are slightly exposed to the air. This allows for the rhizomes to dry and prevents rot, ensuring a good start for the next growing season.
