Following on from last month's announcement of the top 10 pests, the Royal Horticultural Society (RHS) has announced its Top 10 Garden Diseases. This list is based on enquiries received by the charity's Advisory Service at RHS Garden Wisley.

For the 18th year running, honey fungus tops the list with its presence confirmed on 78 different plant genera. Not surprisingly, the weather influenced the list and mild, wet weather is thought to be behind a record increase in box blight cases, with enquiries reaching their highest levels since the RHS began keeping detailed digital records in 1996.
