When to harvest l.jpg
when to harvest

  • peak oil

  • just before the flowers first open, when they are in the bursting bud stage

  • early morning after dew has evaporated

  • discard any spotty or damaged leaves

  • rinse herbs in cool water to remove livestock and soil and gently shake to remove excess moisture

Drying l.jpg

easiest method of preserving herbs


  • air drying / hanging

  • dehydrator

  • microwave

  • oven

Herb type l.jpg
herb type

  • less tender herbs

    • rosemary, sage, thyme, summer savory and parsley

    • easy to air dry

  • tender leaf herbs

    • basil, oregano, lemon balm, mints

    • high moisture content and will mold if not dried quickly

Air drying l.jpg
air drying

  • warm, dry, airy, dark room

  • hanging – long stemmed herbs

  • paper bag with holes will keep dust off and collect any seeds

  • trays – short stems and small leaves

  • will take 1 to 2 weeks

Dehydrator l.jpg

  • temperature and air circulation can be controlled

  • spread herbs in a single layer on tray, leaves attached to stems

  • dry two to ten hours at 100°F

  • check periodically, drying times vary

  • herbs are dry when they crumble and stems break when bent

Slide9 l.jpg

  • lay the herbs on a paper towel, without allowing leaves to touch

  • cover with another towel and layer of leaves - five layers may be dried at a time

  • dry in a very cool oven

  • oven light of an electric range or the pilot light of a gas range furnished enough heat for overnight drying

  • leaves dry flat and retain good color

Microwave l.jpg

  • works well for small amounts

  • place between paper towels

  • medium setting for 2 -3 minutes

  • check for dryness and repeat at 30 second intervals

  • leaves should be brittle and crumble easily

  • requires careful attention!

Storing dried herbs l.jpg
storing dried herbs

  • leave whole and crumple as needed, or coarsely crumpled before

  • seeds can be stored whole and ground as needed

  • place in airtight containers

    • if condensation forms, drying is not complete

  • store in a cool, dry, dark area to protect color and fragrance

  • label each - they will look alike when dried!

  • shelf life is generally one to two years

    • according to Penzey’s herb and spice catalog “old spices never go bad, they just fade away”

Using dried herbs l.jpg
using dried herbs

dried herbs are stronger than fresh

general rule: dried herbs = 3 to 4 times fresh

Freezing l.jpg

  • freezing is best for herbs with soft, lush green leaves

    • basil, chives, cilantro, dill, fennel, , mint, parsley, sweet cicely

    • will become limp in the process, but their flavor and color will be intact

  • to blanch or not to blanch?

Freezing cont l.jpg

  • sprigs can be frozen directly

  • OR chop finely, put in ice cube trays and top with water.

  • in most cases you will not need to thaw before use

Slide16 l.jpg

  • garlic in oil

    • health risk
