Planting Conditions

For optimal growth, plant Cirsium 'Trevors Blue Wonder' in well-draining soil enriched with organic matter. Choose a sunny location with at least 6 hours of sunlight daily, although partial shade is tolerated. When planting, ensure the crown of the plant sits at soil level. Water deeply after planting to settle the soil around the roots. While this variety is drought-tolerant once established, regular watering during the first growing season promotes root establishment. Mulch around the base of the plant to conserve moisture and suppress weed growth.

Watering & Feeding

During the growing season, water Cirsium 'Trevors Blue Wonder' regularly, especially during dry spells, ensuring the soil remains consistently moist but not waterlogged. Once established, it becomes more drought-tolerant. Apply a balanced fertiliser every 4-6 weeks during the growing season to promote healthy growth and flowering. Avoid over-fertilising, as this may lead to leggy growth. Additionally, mulch around the base of the plant with organic matter to retain soil moisture and suppress weed growth, contributing to the plant's overall health and vigour.

General Care

For general care of Cirsium 'Trevors Blue Wonder,' ensure the plant receives sufficient sunlight and well-drained soil. Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding. Prune any dead or damaged stems as needed to maintain the plant's health and appearance. Watch for signs of pests or diseases, such as aphids or powdery mildew, and treat promptly if detected. Provide support to taller stems if necessary to prevent them from bending or breaking.
