What would be the cause of an outbreak of white mushy globules on the wood and branches of a pink flowering rhododendron? The shrub is 30+ years old and at least 15 foot tall, it has not been looked after by previous owner for many years, it gets morning sunshine but is protected from harsh afternoon sun. Many thanks, Pam
