Ask the Plant Nursery: How Do You Dry and Store Garden Herbs?

Your local plant nursery  will tell you that herbs are usually at their best when freshly picked. But, if your plants are producing too much for you to use, drying and storing the leaves is a far better option than watching the herbs wither and die.

Dry and Store Garden Herbs

Preserving your garden herbs is a simple, inexpensive task. Here’s how the plant nursery experts of Millcreek Gardens recommend making herb gardens last all year long.

How to Harvest Garden Herbs

Mid-morning is generally considered the best time to harvest herbs. Cutting the plants soon after the morning dew has dried can help preserve flavor.

To harvest, simply cut healthy branches from your herb plants. Remove any leaves that appear dried or wilted and, if necessary, brush or shake away any insects. If the stems or leaves need a rinse, make sure to blot them dry carefully.

How to Air-Dry Garden Herbs

Plant nursery professionals recommend air-drying for low-moisture herbs, including oregano, thyme, rosemary, marjoram and dill. To air-dry herb plants, follow these steps:

  • Tie a small bundle of branches together, using a piece of twine, string or a rubber band.
  • Place the bundle upside-down in a paper bag.
  • Close the end of the paper bag, being careful not to crush the herbs.
  • Poke a few holes in the bag for ventilation.
  • Hang the bag in a warm, airy room.

Check on your herbs in about a week to see if they are dried and ready for storage. Keep in mind that, depending upon the herb variety, drying could take another week or two.

How to Oven-Dry Garden Herbs

Oven-drying is the preferred plant nursery method for herbs that have a high moisture content, including mint, basil, chives and tarragon. Here’s how to oven-dry your herbs:

Place a single layer of herb leaves on a baking sheet.
Put the baking sheet in an oven set on low heat, 180 degrees or less.
Leave the oven door cracked open a tiny bit.

Check the herbs in two hours. If the leaves crumble easily, the drying is complete. With some herb varieties, oven-drying can take up to four hours.

How to Store Dried Garden Herbs

For the best flavor, plant nursery professionals recommend keeping herb leaves whole – don’t crush them up for storage. To keep them fresh, place the leaves in airtight containers, like glass jars or freezer storage bags.

Dried herbs are best used within a year of harvest. So, make sure to label your storage containers with names and dates.
