A frost is expected to have scorched a substantial number of plants, which is likely to delay the first crop next month.
A growers’ spokesman said: “In between wintry showers, conditions for planting have been favourable and we are making progress ahead of the same period last
“Ideally we would like to see an increase in temperature and sunlight. Almost three quarters of the crop is planted but the weather over forthcoming weeks will determine the development of the crop.”
Early volumes of Jersey Royals are crucial to growers’ incomes as they command a significant premium before greater quantities arrive.
Last year, producers missed out on this bonanza because of severe wintry weather.
