How to care for Hibiscus syriacus 'Red Heart'

Light:
Grows best in full sun for maximum flowering, but will tolerate partial shade with slightly reduced bloom production.

Soil:
Prefers well-drained, moderately fertile soil. Adaptable to most soil types, including slightly alkaline soils, as long as drainage is good.

Water:
Water regularly during the first growing season to help establish strong roots. Once established, it is reasonably drought-tolerant but benefits from watering during prolonged dry periods.

Pruning:
Prune in late winter or early spring before new growth begins. Remove any dead or weak branches and shape as required. Flowering occurs on new growth, so pruning encourages better blooms.

Hardiness:
Fully hardy throughout the UK and able to withstand frost and cold winter temperatures once established.

Feeding:
Apply a balanced fertiliser in early spring to support healthy growth and flowering. Mulching around the base helps retain moisture and improve soil condition.

Large white flowers with a bold deep red central eye.

Blooms from mid to late summer, extending into early autumn.

Excellent for borders, screening, or as a specimen shrub.
