Properly dried herbs retain potency for a full year or more. The keys are harvesting at the right time, drying quickly without heat, and storing away from light and air. This simple practice gives you your own apothecary and spice cabinet from your garden.
Method
- Harvest in the morning after dew has dried, just as flowers begin to open. This is when essential oils peak.
- Bundle 5–10 stems together with a rubber band — rubber bands tighten as stems shrink.
- Hang upside down in a dry, well-ventilated, dark space. A pantry, attic, or shaded porch works well.
- For large-leafed herbs (basil, mint): remove leaves and spread on a mesh screen or window screen to dry flat.
- For seeds (coriander, dill, fennel): cut whole heads into a paper bag and hang the bag. Seeds will fall in as they dry.
- Check after 1–2 weeks. Herbs are ready when they crumble between your fingers.
- Strip leaves from stems. Store whole (not ground) in labeled glass jars with tight lids.
- Keep in a dark cupboard. Grind only as needed — whole herbs last 2–3x longer than pre-ground.
Tips & Notes
- A dehydrator at 95°F is faster but not better than air drying — gentle air drying preserves more volatile oils.
- Test potency: crush a bit between your fingers. If the scent is strong, the herb is still good.
