Harvesting Peppermint for Peppermint Tea

Harvesting peppermint you've grown yourself is such a rewarding experience, and lets you enjoy the freshest, most delicious, fragrant peppermint tea - as well as the many wellness benefits this amazing herb provides - any time you'd like.

Peppermint is an incredibly simple herb to grow (learn more here about growing peppermint), and harvesting peppermint is so very easy, as well.

Here are some tips on harvesting peppermint stalks and leaves, as well as some suggestions for drying your harvest so you don't waste any of that delightful, healthful peppermint.

A special thanks to my mom, Bette (an enthusiastic, lifelong herbalist), for her invaluable tips and information about growing and harvesting peppermint!

Harvesting Peppermint

Leaves from the peppermint plant can be harvested at any time, but young peppermint leaves and stems tend to have a better (less bitter) flavor than the older leaves and stalks. Keep in mind, as well, that the plant's essential oils are strongest and more concentrated in the leaves earlier in the day, so pick peppermint leaves in the morning if you can (just after any dew has dried) to take best advantage of their beneficial oils.

If you are harvesting peppermint stalks, cut or snip them about 3 inches (7 - 8 cm) from the base of the plant. Also, if you're planning to dry your peppermint, the best time to harvest it is before it flowers, when the leaves are chock-full of healthful essential oils. (Herbs tend to dry better without flowers on the stems, as well.)

And don't worry about picking peppermint leaves and stalks often - harvesting peppermint frequently encourages lush new growth. This prolific herb will grow back very quickly, and pruning or pinching back the plant will help to keep it healthy and producing well, and looking prettier and less "woody," too.

Fresh peppermint leaves can be used right away to make peppermint tea or in restorative peppermint tea steam.

Caring for potted peppermint

Even potted peppermint plants will grow quickly! Keep an eye on your peppermint and, when its roots begin to outgrow its pot, divide the plant and re-pot to keep the herb healthy and happy. (The extra plant would make a lovely gift for a fellow herbal tea lover.) Get more tips here for growing peppermint.

Drying Peppermint

Because peppermint grows abundantly and spreads quickly, you may find yourself with more fresh peppermint than you can use right away. If so, when you're harvesting peppermint, why not dry the extra leaves to store and use for tea or a tea steam later?

Peppermint can be dried naturally, or the process can be sped up by drying the herb in the oven. Just remember, drying the leaves in the open air (rather than in an oven) will help to retain more of their beneficial essential oils and more flavor and color, as well. 

Drying Peppermint Naturally

To dry peppermint stalks in the open air, first cut or snip the peppermint stems to within about 3 inches (7 - 8 cm) from the base (this encourages robust new growth). Fill your kitchen sink with a few inches of cool, fresh, clean water, and give the peppermint stalks a quick rinse by briefly swishing them through the water. 

You can also hang and dry peppermint bundles in paper bags, which helps to protect the peppermint from dust, and may also help the herb retain more color and essential oils during the drying process. Cut slits in the bags to increase ventilation and prevent moisture buildup.

Remove any damaged, yellowing, or old leaves, and then air dry the peppermint on a soft towel.

Tie a few stems together with string or twine (no more than 5 or 6 stalks, to ensure proper ventilation during the drying process). Hang the small bundles upside down in a warm, dry, well-ventilated spot, away from direct sunlight. (Hanging the bundles upside down encourages the beneficial oils to flow into the leaves.)

After a week or two, when the peppermint leaves are completely dry and brittle to the touch, carefully strip the leaves from the stems.

Peppermint stalks (or just the picked leaves) can also be dried on a fluffy towel, a mesh or wire rack, or a shallow baking tray lined with cheesecloth. Leave the peppermint in an airy, dry, warm place (away from direct sunlight) until the leaves are quite brittle and dry (this may take a week or more).

Drying Peppermint in the Oven

If you don't have space to dry your peppermint on racks or a spot to hang bunches of peppermint stalks, drying peppermint in your oven is a quick, convenient alternative to open-air drying.

First, pick the peppermint leaves and rinse them in cool, fresh, clean water. Air dry the herb thoroughly on a soft towel. 

Preheat the oven to its lowest temperature (140 to 180 F, if possible) (a lower temperature will ensure the herb retains as much of its flavor, color, and beneficial oils as possible).

Spread the leaves in a single layer on a shallow, non-metal baking sheet (if you must use a metal pan, line with parchment paper first).

Combining drying methods

As an extra precaution against mold in dried herbs, you can also combine drying methods. After thoroughly drying peppermint in the open air, place it in an oven preheated to the lowest setting for 45 minutes or more to ensure the herb is absolutely dry before storing it.

Pop the baking tray onto the center rack in the oven, and turn off the oven. Keep the oven door closed, allowing the peppermint to dry completely. Depending on your oven, this may take 45 minutes or up to 2 hours or more. Check the peppermint every so often, and remove it from the oven when it is thoroughly dry and brittle.

Cool the peppermint completely before transferring it to storage containers.

Storing Dried Peppermint

Once the peppermint leaves are completely dried, it's best not to crush or crumble them (this was cause flavor to be lost). Instead, place them whole in an air-tight, non-porous container (such as a large lidded glass jar or ceramic container), and store the container in a cool, dark, dry spot.

When drying this herb, ensure the leaves are completely dried before transferring them to a storage container, as any residual moisture can lead to mold developing later. Check stored peppermint often for the first few weeks and, if you notice any signs of moisture, pull it out of its container and re-dry.

Storing leaves in this way will help to retain the dried herb's delightful flavor, intoxicating aroma, and beneficial oils, and it will also prevent the peppermint from "sharing" its potent fragrance with other herbs or foods nearby!

Stored properly, dried peppermint can retain its flavor and beneficial goodness for many months, even a year or longer.
