Tall Bearded Iris 'Alizes' should be watered thoroughly but infrequently once they are established, as their rhizomes are susceptible to rot if kept too moist. During the growing season, provide approximately an inch of water per week through rainfall or irrigation, letting the soil dry between waterings. In hotter, dry climates, you may need to water more frequently, but always allow the top few inches of soil to dry out before adding more water. Reduce watering after flowering has finished and during the winter months to prevent rot. Since they are drought-tolerant, it's better to underwater than to overwater.
Tall Bearded Iris 'Alizes' thrives best in full sun conditions, which means they should receive at least six to eight hours of direct sunlight each day. The ideal spot for planting them would be in a location that receives unobstructed sunlight for the majority of the day. Although they can tolerate light shade, too much shade can result in fewer blooms and a heightened risk of disease.
Tall Bearded Iris 'Alizes' prefer temperate climates and can generally survive in temperatures ranging from 5°F to 90°F. The ideal temperature for robust growth and flowering typically lies between 60°F and 75°F. These Irises go dormant in winter and can tolerate cold temperatures but should be protected from extreme cold by mulching over the rhizomes in areas with harsh winter conditions.
Prune Tall Bearded Iris 'Alizes' by removing any dead or damaged leaves and spent flower stems to encourage proper air circulation and prevent disease. The best time to prune is immediately after flowering when you can cut back the flower stems to their base. Additionally, in late summer or early fall, trim back foliage by about a third to shape the plant and remove any old leaves to prepare for the next growing season.
The Tall Bearded Iris 'Alizes' thrives in well-draining, fertile soil with a slightly acidic to neutral pH of 6.5 to 7. To create an ideal soil mix, blend loamy garden soil with compost and coarse sand to ensure good drainage. Avoid soil that retains too much water, as this can lead to rhizome rot.
Tall Bearded Iris 'Alizes' typically do not require frequent repotting. They should be divided and replanted about every 3-4 years or when the clumps become crowded and flowering diminishes. Replant division in a well-draining soil mix to encourage healthy growth.
- Humidity & Misting
Tall Bearded Iris 'Alizes' is tolerant of a wide range of humidity conditions and does not require specific humidity levels. These irises are more dependent on proper soil moisture and do well in the average outdoor humidity found in their growing zones.
- Suitable locations
Place in bright light, ensure good air circulation.
Full sun, well-drained soil, divide every 3-4 years.
- Life cycle
The Tall Bearded Iris 'Alizes' begins its life cycle when the mature plant's rhizomes, which are underground stems, sprout new shoots in early spring. These shoots grow into leafy stems that can reach up to three feet tall, and by late spring, distinctive colorful flowers bloom, showcasing the variety's unique coloration. After blooming, which usually occurs for a period of 3-6 weeks, the flowers fade and seed pods may form, although gardeners often remove spent blooms to encourage reblooming and to maintain plant vigor. Throughout the summer, the foliage remains green and photosynthetically active, supporting the plant's growth and rhizome energy storage. As fall approaches, the leaves may begin to die back as the plant enters dormancy to conserve energy for the winter. In winter, the rhizomes remain dormant underground, protected from the cold, until they resume growth the following spring, repeating the cycle.
Midsummer to early fall
Propogation: The most popular method of propagating the Tall Bearded Iris, commonly known as 'Alizes', is by division. This is typically done after the flowering season has ended, which for Irises is generally late summer to early fall, when the weather is cooler. To propagate by division, you begin by lifting the Iris clump from the ground with a shovel or fork, taking care not to damage the rhizomes. Then, using a sharp knife, you separate the rhizomes, ensuring each piece has at least one fan of leaves and a section of roots. Trim the leaves to about a third of their length to reduce water loss. Finally, replant the rhizome pieces 12 to 24 inches apart and just deep enough so that the top of the rhizome is slightly below the soil surface, or approximately an inch deep (2.54 centimeters), to allow for new growth and adequate sunlight exposure.
