Care Guide:

Light: Iris pseudacorus 'Berlin Tiger' thrives in full sun to partial shade. It prefers at least 6 hours of direct sunlight per day to promote optimal flowering. However, it can tolerate some shade, especially in regions with hot summers, where it benefits from protection against intense afternoon sun.

Water: Yellow Flag Iris prefers consistently moist soil. It is a water-loving plant and thrives in wet or boggy conditions. Ensure the soil is evenly moist but not waterlogged. It can tolerate short periods of standing water, but prolonged waterlogging should be avoided. Regular watering is important, especially during dry spells or in sandy soil.

Soil: Iris pseudacorus 'Berlin Tiger' prefers fertile, loamy soil that is slightly acidic to neutral pH. It can tolerate a wide range of soil types, including clay, loam, or sandy soil. The soil should be moist and well-draining to prevent waterlogging. Amending the soil with organic matter, such as compost or well-rotted manure, before planting can improve its fertility and moisture retention.

Temperature: Yellow Flag Iris is hardy in USDA hardiness zones 4-9. It is adaptable to various climate conditions but performs best in areas with cool to mild summers. It can tolerate both heat and cold, but in regions with extremely hot summers, providing some shade during the hottest part of the day can help protect the plant.

Fertilizer: Yellow Flag Iris is generally a low-maintenance plant that doesn't require heavy feeding. However, you can apply a balanced slow-release fertilizer in early spring or incorporate a granular fertilizer into the soil before planting. Follow the package instructions for application rates. Avoid excessive use of nitrogen-rich fertilizers, as they can promote lush foliage growth at the expense of flower production.

Pruning: Minimal pruning is required for Yellow Flag Iris. After the flowering period, you can remove any spent flower stalks to maintain a neat appearance. In late fall or early spring, you can trim back the leaves to a few inches above the ground to allow for new growth.

Pests and Diseases: Yellow Flag Iris is generally resistant to pests and diseases. However, it may occasionally be affected by aphids, iris borers, or snails. Monitor your plants regularly and take appropriate measures to control any infestations. Good air circulation and proper spacing between plants can help prevent fungal diseases.

Iris pseudacorus 'Berlin Tiger' is a stunning and eye-catching perennial that adds vibrant color and unique markings to garden beds, borders, or water gardens. By providing the right growing conditions and proper care, you can enjoy the striking flowers and architectural foliage of this cultivar in your landscape.
