Harvest Tips
Pinch or cut leaves anytime after plant is established (6-8 weeks). Harvest in morning after dew dries for maximum flavor. Cut stems just above leaf nodes. Regular harvesting promotes bushiness. For drying, cut stems when flowers are just beginning to open. Hang-dry in bundles in warm, dark, well-ventilated area.
Fun Facts

- 🌱 Thyme was burned as incense in ancient temples and given to knights before battle to inspire courage; the word 'thyme' may derive from Greek 'thymon' meaning 'to fumigate'.
