Abstract: A pack of seedling plants includes a sealed, sterile dish containing an agar gel in which seedlings have been raised from seed sown in the gel. The pack may also include a growing tray for which a pack of compost may be provided, and a transparent cover which together form a propagator into which seedlings may be transplanted from the dish. The dish may be fixed to a backing and the various components of dish and backing, tray and cover snap fitted one with another to form a convenient package which also has the advantage of being rearrangeable to provide a robust package for the mail-order market.
