There is nothing better than the flavor and aroma of herbs harvested fresh from the garden. I really miss it when the garden season is over. While I do grow many herbs in containers over the winter to use in cooking, I also like having plenty of dried herbs on hand. Most of the flavors of fresh herbs will be lost in meals that are simmered or cooked for a long period of time.

The intense and concentrated flavor of dried herbs works better for meals that are cooked slowly such as soups, stews, and roasts. Instead of purchasing dry herbs and teas, I try to grow, harvest, and preserve my own.

How to Harvest Herbs for Drying

Herbs can be harvested as needed throughout the growing season once there is enough foliage on the plant to support growth. Snipping the plants regularly help to encourage new growth and keep the herbs healthy. Limit these harvests to less than one-third of the plant so it keeps growing and producing more foliage. The ideal time to harvest most herbs for the best flavor is early in the morning right after the dew evaporates, but before the sun’s rays evaporate the aromatic oils.

When to Harvest Herbs for Peak Flavor and Aroma:

Herbs that you plan to dry for storage should be harvested at their peak to conserve the herbs’ natural oils responsible for flavor, aroma, and medicinal properties. The timing depends on the plant part you are harvesting and how it will be used:

  • Foliage: Herbs grown for their foliage should be harvested before the plant blooms. The flavor of the leaves turns bitter after the plant flowers and begins to go to seed.
  • Flowers: Herbs grown for flowers have the highest oil concentration and flavor when picked just after flower buds appear but before the blooms open fully.
  • Seeds: Herbs grown for their seeds should be harvested after the seeds mature and dry on the plant. They will usually turn dark brown or black when ready.

Harvest leafy, annual herbs like basil and marjoram by pinching off leaves from the tips of the stems right above a pair of leaves. The plant will sprout two branches above the leaves and continue to grow.

How to Gather Herbs:

Choose healthy foliage, flowers, or seeds for drying. Use scissors to clip off the stems cleanly. Discard any moldy, diseased, or insect damaged parts.

  • Leafy Annual Herbs: Harvest leafy, annual herbs like basil and marjoram by pinching off leaves from the tips of the stems right above a pair of leaves. The plant will sprout two branches above the leaves and continue to grow. This is also called “pinching off” and encourages the plant to become bushy and produce more tender foliage. Harvest leafy tips frequently and clip off flower buds to keep the plant producing. Harvest the entire plant before your first frost.
  • Leafy Perennial Herbs: Perennial herbs such as thyme, sage, and tarragon can be harvested by the stem or sprig. Harvest the herb by cutting the stems 3-4 inches from the base of the plant. Harvest herbs with long stems like parsley and oregano by cutting the stem near the base of the plant. Harvest rosemary by cutting stems above a pair of leaves and it will branch out and continue to grow. Continue to harvest perennial herbs until about 4-weeks before your first frost. As winter approaches, allow the plant to focus on winding down for the season before going dormant.
  • Blossoms: Some herbs have single flowers, while others present their blooms in clusters along a stem, or spikes. Single blossoms such as chamomile, calendula, and feverfew are harvested by picking the individual flowers when the flower is opened fully. Harvest spiky blossoms when some of the flowers are open by cutting the stem several inches from the base of the plant or above the top set of leaves.
  • Seeds: Herbs harvested for their seeds, such as anise, caraway, coriander, and dill are dried mostly on the plant. Allow the herb to form flowers and go to seed. After flowering, seeds swell and ripen from green to brown or black as they dry. Seeds are ready to pick when they are dry. Most often, seeds will spill out when the seed head is touched. Hold a container under the seed head and clip the stem so the seed cluster falls into the container along with any seeds released.A dehydrator works by circulating a gentle flow of air through screens.

How to Dry Herbs for Storage

After harvesting, you want to dry herbs quickly to preserve their essential oils for the greatest flavor intensity and medicinal properties. I don’t add moisture by rinsing my herbs, unless I can see visible dust or pests. Herbs must be dried completely before storing in jars. Ideal drying environment is in a dark, warm, dust-free area with good air circulation. Leaves are ready for storage when they feel dry and crumbly. Here are several methods to dry herbs for storage:

  • Hang and Air Dry Herbs: Air-drying is the easiest method to dry herbs with stems. Tie the stems into small bundles and hang them upside down in a dry, warm, dust-free, and airy place out of direct sunlight. I like to use elastics around the stems because they will still hold the bunch together as the stems shrink when they are dry.
  • Air Dry Herbs Using a Drying Screen: Alternatively, you can spread the herbs out on a window screen or drying screen to dry. Suspend the drying screen over two chairs so the air can circulate above and below the screen. See how to make your own drying screen or check out these Stacking Herb Drying Racks from Gardener’s Supply.
  • Use a Food Dehydrator: Our summers here in Maine are humid, and the moisture in the air can prevent some herbs from air-drying naturally. I use a food dehydrator to dry herbs faster. A dehydrator works by circulating a gentle flow of air through screens. Use low heat so you don’t degrade the quality of the herbs.
  • Further Drying Seeds: Remove the seeds from the seed heads and spread out in a shallow layer in an open container to dry further for about 1-2 weeks. Separate the seeds from the seed head and chaff.
  • I like to place the seed heads in a paper bag with a few holes poked in the top for air. After a few weeks, I give the bag a good shake to release the seeds from the seed head. Then I separate the seeds from the dried plant material and spread them out in a shallow container for additional drying before storing.

After flowering, seeds swell and ripen from green to brown or black. Seeds are ready to pick when they are mostly dry.

How to Store Dry Herbs:

Once the herbs are completely dry and brittle, remove the leaves from the stems and store loosely in clean glass jars or containers with airtight lids. To retain the herbs’ flavor and potency, don’t crush or crumble them until just before using. Label your jars the name of the herb and the date.

Store your jars in a in a cool, dark place, away from heat, humidity, and temperature fluctuations. Believe it or not, the kitchen cabinet is not the ideal place to store dry herbs. I keep the bulk of my herbs stored in large jars in a in a cool, dark little-used closet. I fill up small herb jars with about a month’s worth of herbs for the kitchen cabinet. Dried herbs will remain potent for at least six to 12 months when stored properly.

Once the herbs are completely dry and brittle, remove the leaves from the stems and store loosely in clean glass jars or containers with airtight lids. To retain the herbs’ flavor and potency, don’t crush or crumble them until just before using.

Keep in mind that strength in dried herbs is more concentrated than fresh herbs. If you have a recipe that calls for fresh herbs, substitute with about one-third the amount of dried herbs.

Ingredients

  • 1 bunch fresh herbs of choice
  • twine drying screen or food dehydrator
  • 1 glass jar for storing

Instructions

  • Gather herb clippings, and remove any yellowed, dead, or diseased pieces.
  • Grasp firmly by the stems and give the herbs a good shake to dislodge debris and insects.
  • Dry using one of the following methods:
  • Hang and Air Dry: Remove the lower leaves, tie the stems into small bundles, and hang upside down in a dry.
  • Drying Screen: Spread the herbs out on a drying screen. Suspend the screen over two chairs so the air can circulate above and below the screen.
  • Let herbs dry in a warm, dust-free, and airy place out of direct sunlight. Herbs with small leaves like thyme, oregano, and rosemary will take about 6 days to dry out completely. While larger leaves, like basil and parsley, can take up to 2 weeks.
  • Food Dehydrator: Preheat food dehydrator to 100˚F. Place the herbs in a single layer on dehydrator trays and place in the dehydrator until herbs are dry, 1 to 4 hours depending on the type of herb. Check occasionally to prevent over drying.
  • Once the herbs are completely dry and brittle, remove the leaves from the stems and store loosely in clean glass jars or containers with airtight lids.
  • Store the jars in a in a cool, dark place, away from heat, humidity, and temperature fluctuations. Dried herbs will remain potent for 6 to 12 months when stored properly.

    How long does one let dried herbs hang after they are dry or must the leaves be taken off the stems soon after dry in order to preserve fragrance, oils & nutrition

    1. Penny, If you leave the herbs hanging after they are dry, they could absorb moisture or accumulate dust or insects. I highly recommend storing them in airtight containers once the herbs are dehydrated.

  2. I lay my oregano on sheets of paper towel, then cover them with another layer of paper towel and lay in the sun coming through my window in the morning. They dry perfectly in two days and don’t seem to lose their aroma. But I’m wondering if putting them in the sun, albeit through glass and covered by paper, isn’t removing some of the fragrant oils anyway. Any thoughts on this? Thank you

  3. Here it is the beginning of spring and for example my plantain has rows of foliage however it is not flowering yet. In this instance I would like to harvest some of these beautiful green leaves and dehydrate them as they will die back before the plant has reached its peak and begun to flower. I would like to maximise the amount of dried plantain I can have. Would you still wait for the herb to reach flowering stage before harvesting and lose potential leaves that could be dried?

  4. Is there a way to dry and preserve parsley root that doesn’t require buying an expensive home dehydrator or freeze-dryer?

  5. Why keep them out of direct sunlight when drying I was thinking of putting a circle hanging rack to dry my herbs on in my greenhouse is this not a good idea?

    1. Nicole, Drying herbs in direct sunlight can cause the herbs to lose color and flavor. It is the same when storing jars of herbs. It is better to keep herbs out of the sun when drying and storing.

  6. Love the idea of using the paper bag with holes in the top! I like hanging my herbs to dry (they look so pretty), but the humidity usually kicks in by July and I switch over to the dehydrator.
