Thymus Coccineus (Thyme) ground cover grows best in a warm sunny spot (the more sun it receives, the stronger the flavour if using in cooking), in well-drained soil. They look best grown at the front of a border where you could try grouping different varieties together. It is fairly drought tolerant and needs a well-drained, preferably alkaline, soil. Do water it well after planting, but it will grow well once established in fairly poor, even stony, soil. If you have soil with poor drainage – simply keep Thymus in pots where they will be quite happy.
As a rough guide when planting Thymus Coccineus as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage, and 9-12 will make a weed supressing carpet very quickly.
