Leaves that decay, or are destroyed without using Silk Touch or shears , yield saplings 5% ( 1 ⁄ 20 ) of the time, sticks 2% of the time, and otherwise drop nothing. Jungle leaves drop saplings 2.5% ( 1 ⁄ 40 ) of the time. Oak and dark oak leaves also have a separate but additional 0.5% ( 1 ⁄ 200 ) chance of dropping an apple , making it extremely rare but possible for a single leaf to drop a sapling, a stick and an apple at the same time.
