Caring for a Blue Hobbit (Eryngium 'Blue Hobbit') involves providing it with the right growing conditions to thrive. Here's a breakdown of how to care for this striking perennial:
Sunlight and Soil
- Sunlight: Blue Hobbit requires full sun (at least 6 hours of direct sunlight per day) to flourish and maintain its vibrant blue color.
- Soil: It thrives in dry, well-drained soil that is poor to moderately fertile. Good drainage is crucial, especially during winter, to prevent root rot. Amend heavy clay soils with grit or sand to improve drainage.
Watering and Feeding
- Watering: Once established, Blue Hobbit is drought-tolerant and doesn't require frequent watering. Avoid overwatering, as this can lead to root rot. Water deeply only when the soil is dry to the touch.
- Feeding: Avoid excessive fertilization, as it can lead to weak growth and reduced flowering. If needed, apply a light application of a balanced fertilizer in the spring.
Winter Care
- Protection from Winter Wet: This is crucial. Eryngium plants are susceptible to crown rot in cold, wet soil during winter. Ensure the soil is well-draining, and consider adding a layer of gravel around the base of the plant to improve drainage and airflow. In colder climates, consider a light winter mulch of straw or evergreen boughs to protect the crown.
Pruning and Deadheading
- Deadheading: Remove spent flower heads to encourage further blooming.
- Pruning: Cut back the plant to the ground in late autumn or early spring.
Drying Flowers
- Harvesting: If you want to dry the flowers, pick the stems just as the flower clusters are fully open.
- Drying: Hang the stems upside down in a warm, dark, and well-ventilated place until completely dry.
Potential Problems
- Root Rot: The most common problem, caused by poorly drained soil, especially in winter.
- Pests: Generally pest-resistant, but watch for aphids or other common garden pests. Treat as needed with insecticidal soap.
By following these guidelines, you can ensure your Blue Hobbit thrives and adds a beautiful splash of blue to your garden.
