Abstract: A plurality of freestanding non-porous planting blocks, each containing a plurality of tapered planting cells, are used in conjunction with a water container. Each planting cell has non-permeable sidewalls as well as open top and bottom apertures. The bottom apertures of the planting cells on the bottom surface of the corresponding planting block, will be submersed in water within the container allowing for subirrigation. The container can be an in-ground reservoir or a manufactured container of permanent or portable nature. Plant material placed in the planting cells, with or without planting media, will grow into field-ready plants for storage or harvest. The system is used for economically enhanced plant production of field-ready trees, shrubs, forbs, perennials, vegetables and grasses.

Abstract: A plant nursery and storage system for use in the growth and storage of field-ready plants. At least one planting block with tapered planting cells therein and extending openly from the top surface to the bottom surface thereof is placed in a container holding water. Plant material placed in the planting cells, with or without planting media, will grow into field-ready plants. The growing plants will be sub-irrigated by accessing water through the open base of the planting cells contacting the water in the container. The sub-irrigation technique of the invention replaces industry standards of top irrigation and bottom aeration for plant production, and addresses high costs associated with current production methods in the production of field-ready trees, shrubs, forbs, perennials, vegetables and grasses.
