Overview

• Both outlets point to 10–12 as the window when essential‑oil levels peak in culinary herbs, yielding the strongest flavor and scent.
• Dry, sunny spells enhance aroma, whereas recent rain or heavy dew dilute essential oils, so gardeners are urged to wait for a dry morning.
• Cuts made before flowering retain more leaf aromatics because plants divert resources once buds form.
• Woody Mediterranean herbs such as rosemary, thyme, oregano, sage and lavender dry well, while tender types like basil are best used fresh to avoid aroma loss.
• Preservation guidance includes air‑drying in a ventilated, shaded spot (~20–30°C), low‑temperature oven drying with the door ajar (about 40–50°C), careful microwave use for small batches, and dehydrators set to gentle heat, with several tips advising sub‑40°C to protect oils and vitamins.
