In the middle of the night, workers in a Slovakian orchard carefully place paraffin flames under cherry trees. The candles are part of a fight to save their precious buds against spring frost. To maintain a temperature between -1 and 0 degrees they use several techniques: candles, pellet stoves, and smoke projecting machines for the cherry trees. Apple trees, meanwhile, are covered in ice, a procedure which creates a bubble around the buds, maintaining the most sensitive parts at a temperature of 0 degrees. "It is a very very hard night shift and I hope that we saved something" says Martin, in charge of the cherries in the orchard. IMAGES AND SOUNDBITES
