In the middle of the night, workers in a Slovakian orchard carefully place paraffin flames under cherry trees to protect them from the frost. 

In the middle of the night, workers in a Slovakian orchard carefully place paraffin flames under cherry trees to protect them from the frost. 

They are using candles, pellet stoves, and smoke-projecting machines to maintain a temperature between -1 and 0 degrees to save the cherry trees. 

Apple trees, meanwhile, are covered in ice, a procedure which creates a bubble around the trees' 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, who is in charge of the cherries in the orchard.
