A method and an apparatus is proposed for drying stacked wood with the help of a drying gas guided in a circulatory flow. The stacks of wood (H1, H2) are charged zone by zone depending on the average moisture of the wood (u) in the respective zone with partial streams of the drying gas which differ with respect to the ir drying power. In order to achieve the most even final humidity (E) of the individua l stacks of woods (H1, H2) it is proposed that the stacks of wood are dried in the zo ne with the on average highest wood moisture (u) with a permissible maximum speed up to the fiber saturation point (F) and the other zones (2) are dried within the terms of achieving the fiber saturation point (F) with different speeds in the time interval as predetermined by the zone with the most moisture before the stacks of wood (H1, H2) are dried in an even circulatory flow to the predetermined final moistur e (E), and that the average moisture of the wood used for determining the drying speeds is determined in a heat-up phase (A) from the heat quantity supplied to the wood.
