There will be events at National Trust properties and in community orchards (www.orchardnetwork.org.uk).
Starting in the heart of the south west the festival will kick off at the National Trust's Cotehele in the Tamar Valley on Sunday 25 April and gradually travel northwards following the emerging blossom across England, ending at Acorn Bank in Cumbria two weeks later on Sunday 9 May.
Kate Merry, orchard officer, said: "Orchards perfectly capture the changing nature of our seasons and the arrival of blossom on fruit trees is a time for celebration. So, why not take the time to seek out fruit trees and orchards where you live and enjoy this annual spring spectacle?"
The Full Bloom festival marks the first anniversary of the launch of the traditional orchard project funded by the National Trust and money from Natural England's Countdown 2010 Fund.
The National Trust is working with Natural England and other organisations to halt the loss of traditional orchards across England and revive their fortunes.
