These trials are for exhibition dahlias. Cultivars are grown with some under covers and others in the open to best assess how they perform in differing conditions. Awards are given after a season’s judging, the overall best cultivar receiving the Harry Howarth Memorial Medal.
For more details or to submit cultivars for future trials, please contact Trials Co-ordinator: Mike Cunningham, 8 Wheathead Crescent, Keighley, West Yorkshire, BD22 6LX. e-mail: mhlc@blueyonder.co.uk
