Salad greens

Cool-season salad greens are often sold in standard cell-packs, ready to plant. The pack will fit nicely in an 8-inch square box edged with tissue paper.

In mild-winter areas, the lettuces can be transplanted into the garden after a few days on a sheltered patio; in cold climates, plant in wide pots on a frost-free porch.
