The flowering time for Rhododendron Cunningham’s White is typically from late May to early June, depending on the climate and growing conditions. During this time, the plant produces large, white, funnel-shaped flowers with yellow-green markings on the upper petals, creating a beautiful contrast with its dark green foliage.
To ensure the best growth and flowering, Rhododendron Cunningham’s White should be fed with a specialist fertiliser for acid-loving plants, such as ericaceous plant food. This should be done once a month from early spring to late summer, following the manufacturer’s instructions.

Pruning is not necessary, but any dead, diseased or damaged branches should be removed promptly.
