ABSTRACT:
The book-type seedling container is provided with shiplap seals extending the full length of the cavity-forming shoulders, without crossover of the shiplap ledges. This shiplap structure is combined with prong-and-socket means pinning the shoulders together at their outer ends. The seal resulting from this combination gives improved resistance to penetration of seedling roots from one cell to another.
