The RHS daffodil Show schedules are available here
PLEASE NOTE: The RHS has banned the use of floral foam at all RHS Competitions.
It has been causing real problems for the garden staff after the shows at Rosemoor and Wisley because it cannot be recycled and it is full of really unpleasant substances (including formaldehyde, barium sulphates and carbon black) Alternative biodegradable staging materials include sustainably sourced moss and newspaper.
