Famously known as Brood II, the 17-year cicadas are due to begin emerging by the end of May. To some, witnessing this natural phenomenon is awesome; to others, menacing and grotesque.
For me, it means calls from clients wondering what to do about their recently planted gardens.
Adrian Higgins, the Washington Post's garden writer, sums it all up nicely. Not everything in your garden is at risk - in fact, unless your garden was planted in the past two years, you shouldn't worry at all. Established trees and shrubs will recover. Perennials and evergreens are not plants in which the cicadas like to lay their eggs.
So no worries, enjoy watching the beastly creatures and be grateful they won't return until 2030.
