Organiser Kim ''Dusty'' Murtagh said the Wetherstons site development and maintenance crew had the site looking ''perfect'', allowing the brewery ruins and fields to remain open to the public all year round. That was, until June's snowstorms.
''The devastation throughout the site has toppled many trees and obscured paths. We are racing to clear the fields before the season, but unless we can get more volunteer helpers, we may have to close sections until next year.''
The snow ruined the marquee, destroyed some of the older hawthorn trees, and damaged paths, Ms Murtagh said.
Daffodil Dayze runs each year during spring, from September 1 to November 30. The event showcases the ruins of Otago's most successful provincial brewery and features walks during which participants can see rare plant species.
This year the central part of the festival will be ''Circus Dayze'' on September 29 with the Lawrence event included in the New Zealand Small Town Conference held in Balclutha.
The 10ha field of daffodils at the former Black Horse Brewery site at Wetherstons was first planted 117 years ago. In its heyday in the 1930s, it attracted thousands of visitors.
Over the years, the varieties cross-pollinated to provide a rare display.
Hart's Black Horse Brewery, at Wetherstons, was on February 28 registered as a Category 1 Historic Places Trust listing.
Ms Murtagh said the registration represented the culmination of eight years of research and lobbying for recognition.
She is a trustee of the Hart's Daffodil Charitable Trust along with four others - landowner Ben Hart, Margaret Young (nee Hart), Craig Morrison, and Jenni Kini.
