About Thyme
Thyme is a drought-tolerant cold-hardy herb that thrives in poor soil and full sun.
Plant in well-drained soil — thyme rots in wet conditions. Prune after flowering to keep compact. Excellent for containers and rock gardens. Cut stems for drying just as flowers open.
Gardening in Colorado
