WaterStandard Dwarf Bearded Iris, commonly called Iris 'Sweet Kate', should be watered deeply to establish a strong root system, especially in the first growing season. Water this plant once a week with about one gallon per plant, ensuring the soil is moist to a depth of about 8 inches but not waterlogged. During the growing season, if rainfall is less than one inch per week, continue to water the plant with one gallon. However, once established, Iris 'Sweet Kate' is relatively drought-tolerant and watering can be reduced. Over-watering or poor drainage can lead to root rot, so allow the soil to dry out somewhat between watering sessions.
LightIris 'Sweet Kate' thrives in full sun, receiving at least six hours of direct sunlight daily. The best spot for this plant is in an area where it can soak up the morning sun, which is less intense, reducing the risk of leaf burn while providing the light needed for optimal growth and bloom development. Partial shade is tolerable, especially in the hottest part of the day, but too much shade will negatively affect flowering.
TemperatureThe Standard Dwarf Bearded Iris 'Sweet Kate' tolerates a wide temperature range but grows best in regions with cool to moderate climates. It can survive minimum winter temperatures down to about -10 degrees Fahrenheit, making it suitable for many temperate regions. The ideal growing temperatures for Iris 'Sweet Kate' are between 55 and 75 degrees Fahrenheit during the active growing and blooming seasons. It can withstand high summer temperatures, but ensure it has adequate water during these times.
PruningPruning of the Standard Dwarf Bearded Iris 'Sweet Kate' is essential for maintaining plant health and encouraging blooms. After flowering, trim off the flower stems to prevent the plant from putting energy into seed production. In late fall or early winter, cut back the foliage to about 4-6 inches from the ground to tidy the plant and reduce the risk of overwintering pests and diseases. Divide and prune the rhizomes every 3 to 5 years in late summer to promote rejuvenation and prevent overcrowding.

Life cycleIris 'Sweet Kate' (SDB), commonly known as Sweet Kate Dwarf Bearded Iris, begins as a dormant rhizome that sprouts in early spring, producing sword-like foliage and stems. In late spring to early summer, the iris flowers, showcasing vibrant blooms that are often shades of purple, yellow, or bi-colored. After flowering, the plant enters a period of vegetative growth where it stores energy in the rhizome for the next season. During summer, the foliage remains but eventually starts to die back as the plant enters dormancy in the fall. Throughout dormancy in winter, the rhizome survives underground, often requiring a period of cold to prompt the next cycle of growth. In the succeeding spring, the cycle begins anew with the emergence of new growth, continuing the perennial lifecycle of Sweet Kate Dwarf Bearded Iris.
PropogationPropogation time
Late Summer
Iris 'Sweet Kate', a variety of Standard Dwarf Bearded Iris (SDB), is typically propagated through division, which is the most popular method. The process involves separating the rhizomes, which are the horizontal underground stems, to create new plants. Propagation by division is best done in late summer, after the flowering period has ended and before the fall rains start. First, you should carefully dig up the clump of irises, taking care not to damage the rhizomes. Wash off the soil and inspect for any signs of rot or disease, trimming off affected areas. Each section of rhizome you replant should include one or two leaf fans. Replant the divisions 12 to 24 inches apart (30 to 61 centimeters), ensuring the top of the rhizome is exposed to the air and sunlight, which is crucial for the health of the plant.
