Care Guide:

Light: Iris sibirica 'Snow Queen' thrives in full sun to partial shade. It prefers at least 6 hours of direct sunlight per day to promote healthy growth and abundant flowering. However, it can tolerate partial shade, especially in hot climates.

Water: This iris variety prefers consistently moist soil but should not be waterlogged. Provide regular watering to keep the soil evenly moist, especially during the growing season. Avoid overwatering, as excessive moisture can lead to root rot. Once established, it can tolerate moderate drought conditions.

Soil: 'Snow Queen' prefers moist, well-draining soil. It can adapt to a range of soil types, including loam, clay, and sandy soils. Ensure the soil is enriched with organic matter to improve its fertility and moisture retention. It prefers slightly acidic to neutral pH levels.

Maintenance: Iris sibirica 'Snow Queen' is a low-maintenance plant. Remove spent flowers to encourage continuous blooming and maintain the plant's overall appearance. In late autumn or early spring, cut back the foliage to about 4-6 inches (10-15 cm) above ground level to promote new growth.

Mulching: Apply a layer of organic mulch around the base of the plants to help retain moisture, suppress weeds, and provide insulation to the roots during extreme temperatures.

Division: Over time, Iris sibirica 'Snow Queen' may develop overcrowded clumps. Divide the plant every 3-4 years in late summer or early autumn to maintain its vigor and promote better flowering. Dig up the clump, separate the rhizomes, and replant them at the desired spacing.

Pests and Diseases: 'Snow Queen' is generally resistant to pests and diseases. However, it may occasionally encounter issues such as iris borers, slugs, snails, or fungal diseases like leaf spot. Monitor the plants regularly and take appropriate measures if any problems arise.
