Creeping Thyme Seeds Ground Cover - 600 Seeds - Scarlet Red Plant creeping thyme seeds directly outside after the danger of frost has passed. Prepare a seed bed, loosen the soil and remove weeds. Scatter the Creeping Thyme ground cover seeds evenly and press them lightly into the soil. Mixing with 5 parts play sand to one part seeds will help distribute them more evenly. Keep the soil consistently moist, but not soaked. Do not allow seeds to dry out. These are tiny tiny seeds so if the top of the soil dries out the seeds will dry out. Thyme prefers a sandy, dry soil. Avoid planting in heavy, wet soils. Creeping Thyme is a beautiful ground cover, between stepping stones or rock crevices, and to edge garden beds.
