Select a container that has one or more drainage holes in the bottom if starting thyme seeds indoors first.
Fill the container to within 2 inches from the top rim with organic potting mixture.
Dig very shallow holes in the potting mixture with your finger, then carefully place several thyme seeds in each hole.
Backfill each hole with potting mixture, then tamp the soil very lightly with your finger. Thyme seeds are very small and don't need much soil to cover them.
Water the soil gently directly after planting the seeds with a fine spray of water, then set the container in a warm, sunny location.
Transplant the seedlings into the garden when they are 2 to 3 inches high, after all danger of frost has passed. Space the thyme seedlings 12 to 18 inches apart.
