Hibiscus Macdelveon's Yellow
Notify MeHibiscus macdelveons Yellow is a deciduous shrub that features large, sunny yellow flowers with a prominent contrasting red centre, creating a vivid display throughout the warmer months. The flowers attract pollinators such as bees and butterflies, making it a wonderful choice for a wildlife-friendly garden. Its lush, green foliage provides an excellent backdrop for the vibrant flowers.
Perfect as a feature plant or within mixed borders, it suits tropical, coastal, or Mediterranean-style gardens. This Hibiscus thrives in a sunny, sheltered position with well-draining soil that remains consistently moist but not waterlogged. Space plants approximately 1.5 to 2 metres apart to allow for airflow and growth.
Mature size: Reaches up to 2.5 metres in height and 1.5 metres in width, forming a compact, rounded shape ideal for mid-sized gardens.
Trimming: Prune lightly in late winter or early spring to shape and encourage new growth. Remove any dead or damaged branches throughout the year to maintain health and appearance.
Deadheading: Regularly remove spent flowers to prolong the flowering season and maintain the plant’s tidy look.
Fertilising: Feed with a balanced, slow-release fertiliser in spring and summer. Supplement with a liquid fertiliser high in potassium every 4–6 weeks during the flowering period for optimal blooms.
Watering: Keep the soil consistently moist but well-draining, especially during the establishment phase and dry spells. Avoid waterlogging, as hibiscus plants dislike overly wet roots.
Pest Control: Watch for aphids, whiteflies, and spider mites. Use insecticidal soap or neem oil for treatment, applying as directed. Regularly check the undersides of leaves for pests.
Disease Management: Monitor for signs of fungal diseases such as leaf spot or powdery mildew. Improve air circulation by spacing plants well, and treat with fungicides at the first sign of infection. Remove affected foliage promptly.
