Rhododendron 'Cunningham's White'
hybrid rhododendron
Marvellous full trusses of white, funnel-shaped flowers with yellow or greenish-brown markings in late spring and dark green leaves, retained all year. This lovely, old hybrid rhododendron is understandably popular, due to its tolerance of poor or near-neutral soil. Compact and robust, 'Cunningham's White' is ideal for growing on a boundary, for use as a windbreak or screen.
How to care for Rhododendron Cunningham's White:
When planting, avoid planting too deeply, and incorporate well-rotted compost or manure into the planting hole, adding some mycorrhizal fungi to aid root establishment. Rhododendrons prefer an acid soil or ericaceous compost that is well-draining.
Remove spent flower heads regularly to encourage prolonged flowering. In late autumn, after flowering has finished, cut back any dead or damaged growth to maintain a tidy shape. In early spring, prune lightly to remove any winter-damaged stems and to promote strong, healthy new growth.
Apply a generous 5-7cm (2-3in) mulch of leaf mould around the base of the plant each spring. Protect from strong winter winds.
