How and Why to Dry your Herbs

We’re big fans of keeping an herb garden, even if it’s in the form of potted herbs on your deck, balcony, or in your yard. Fresh herbs are somewhat easy to maintain throughout the summer, but sometimes you grow more than you can use, and anticipation for colder months means you want to store some of what you grow so you’re not reliant on grocery store herbs.

Different herbs, different timing

Different types of aromatic herbs have a specific stage at which they’re most potent during their biological cycle. At this specific stage, this herb will have the highest concentration of essential oils and resins, making it the best time to collect and dry said herb. For example, mint, spearmint, and basil should be collected before they bloom, while oregano, marjoram, thyme, and lemongrass should be collected in the early stage of their bloom when their flowers are open. Sage flowers, on the other hand, are best collected when they are almost open, and after about a month you can collect and dry the leaves, as well. Other herbs, such as rosemary, can be collected and dried any season.

When and how to dry your herbs

The ideal time to harvest herbs for drying is during the morning after the morning dew has just evaporated. Once you pluck your herbs, the first step is to rinse them clean. Next, tie them by their stems (mindful of the leaves or flowers you’re trying to preserve) with twine. Finally, hang them upside down in a cool, dry place. In other words, avoid anything near your stove where moisture and heat are at play. Once they're hung, check the herbs every couple of days to see how fast the humidity is going. If the herbs are not drying, you may increase the ventilation by opening a window or using a fan in the space. You’ll be able to tell when your herbs are ready and completely dry by picking a leaf and rubbing it gently between your fingers - if dry, it should break easily into small pieces. It may take just a couple of days or even a week, depending on your space, the humidity, and the herb itself!
