New technology also helps fruit yield, while strawberry, raspberry and blackberry output has risen
British blueberries are the latest fruit to benefit from the warmest spring on record, with the harvest up by almost a quarter so far this year.
Growers say the weather has produced an early crop with more and larger berries, while new varieties can bring higher yields and better resilience. About 5,133 tonnes are expected by the end of August, up significantly from almost 4,187 tonnes by the same point last year.
