Simple aligned stacking without alternating layers.
Row or parallel stacking refers to arranging shiitake logs in aligned rows where most logs run in the same direction. It is often used as a quick storage method or as a staging layout during inoculation, soaking, or transport. Unlike crossed methods, it does not rely on alternating layers to “lock” the stack.
Logs are placed in one or more rows, often with multiple layers stacked directly above. Because there is no alternating 90-degree pattern, stability depends on how level the base is and how neatly logs are aligned. Interior logs can be less accessible.
Compared to tonogodhime, row stacking typically provides less cross-bracing and may offer less air movement through the middle unless gaps are maintained.
Because the method is not self-locking, taller stacks can shift more easily, particularly when logs are smooth-barked or wet.
Row stacking can reduce harvest access and inspection efficiency because interior faces are harder to see. It can also create uneven airflow and moisture retention when logs are pressed tightly together.
Row stacking is usually less stable and less accessible than crossed methods such as tonogodhime or crib stacking. It may be comparable in simplicity to lean-to stacking, but lean-to stacks gain stability through external support.
In wet climates, row stacks benefit from spacing that encourages drying and from drainage that prevents logs from sitting in pooled water. In dry climates, tight row stacking can slow drying but can also reduce airflow; placement under partial canopy is often preferred.
Common adaptations include using short separators to maintain gaps, or stacking in multiple short piles rather than one long, tall stack. Some growers treat row stacking as a temporary layout and restack into a more accessible method for fruiting.
