1. Sprinkle. Fill individual pots or a flat of six-packs or cells with moistened commercial seed-starting mix. Sprinkle seeds lightly on soil, following directions on the seed packet; sow one seed or two in each cell or pocket of a six-pack. Cover the seeds with about 1/8 inch of the mix. Press the mix down lightly and spritz the surface with water to moisten it and settle the seeds.
Note: Sow borage, chervil, coriander, dill, and fennel directly in warm garden soil because they don't transplant well from pots.
2. Cover up. Keep the mix moist by covering the container with plastic wrap or a plastic bag; cover a six-pack or flat with a plastic dome. Remove the covering when seedlings emerge. Place the container in a sunny (south-facing) window. Keep the mix evenly moist by watering it from the bottom: Set the containers in a sink filled with 2 inches of water until beads of moisture appear on the soil surface. When the seedlings reach 2 inches tall, transplant them into individual pots or thin those started in small pots to one seedling per pot by snipping off all but the strongest-looking seedling.
