Climate change is threatening the survival of classic British apples, as traditional tree varieties require a certain number of 'chilling hours' to lie dormant during winter. This is necessary for energy conservation and fruit production. However, rising temperatures are preventing these trees from entering this dormant state, leading to a decline in apple crops. To address this issue, the Royal Botanic Gardens, Kew, is experimenting with planting apple trees of various types, including heritage, low-chill, and tropical varieties, to find one that can thrive in London's increasing warmth. The trial includes apples like nonpareil, Cox's orange pippin, Gala, and Fuji, with initial results expected in three years. This initiative aims to find a solution to the challenges faced by apple growers due to climate change and labor shortages.
