Box caterpillar and fuchsia mite top UK garden pests list

The Royal Horticultural Society also warns that a 'game-changing' bacterial disease called xylella poses a very serious danger to UK plants and trees

The box tree caterpillar and fuchsia gall mite will continue their march across British gardens in 2018, experts warn, after the fast-spreading bugs topped the Royal Horticultural Society's (RHS) pest list for 2017.

The RHS also warned that a "game-changing" bacterial disease called xylella, which is devastating parts of southern Europe and has already been intercepted at the UK border, is a very serious danger to UK plants and trees.
