How do you  grow ajuga ground cover?
 Dig a 4-inch layer of organic matter into the soil before planting the ajuga. Plant in early spring after all danger of frost passes. Dig a hole deep enough to accommodate the roots of the plant and set the ajuga in the center of the hole. Cover the roots with soil, but make sure the crown is above the soil surface. Space multiple plants 6 to 12 inches apart.
