Learning how to dry marjoram lets you keep a garden harvest for cooking through the colder months. Marjoram is a leafy herb with a sweet, warm aroma, and university extension publications list it among the herbs that dry well. This guide describes the drying methods those publications recommend, explains how to tell when the leaves are ready, and notes the points where the sources do not give enough detail to be specific.

Quick answer

Harvest marjoram stems on a dry day, after the morning dew has evaporated, and before the plant flowers.
Air dry small bundles indoors in a warm, dry, ventilated room. The Wisconsin extension publication gives a general drying time of 2 to 4 weeks for air drying.
Use a dehydrator set between 95 and 115 degrees Fahrenheit if the air is humid or you need faster results.
Marjoram is dry when the leaves crumble easily and the stems snap when bent. Store the dried leaves in airtight containers away from light.

How we chose

The sources in this guide are university extension publications from Wisconsin, Oregon State, Purdue, and Washington State. Each one covers home herb drying in general and names methods that apply to marjoram. Commercial and recipe websites were not used to support any drying claim. Each source was opened on 2026-10-27, and each quotation was checked against the text of the page or PDF as retrieved.

Why marjoram suits drying

The methods for drying herbs depend on how much moisture the leaves hold. The University of Wisconsin herb-drying publication sorts herbs into two groups. It states that “rosemary and marjoram are well suited for air-drying,” along with sage, thyme, summer savory, dill, bay leaves, and oregano. The same publication places basil, tarragon, lemon balm, and the mints in a separate group of tender herbs with high moisture content, which it says are not as suitable for air drying.

That grouping explains why marjoram is a common choice for home drying. Its leaves are small and fairly sturdy, and they lose moisture steadily when they are hung or spread in a dry room. Because the leaves are small, they also dry quickly once the moisture is gone, which reduces the time the herb spends in conditions where it could mold.

Step one: choose the right time to harvest

The Oregon State University drying guide describes the best time to harvest herbs for drying as just before the flowers first open. The Purdue publication recommends harvesting on a sunny day in mid-morning, after the dew has dried. The timing matters because leaves that are wet with dew are more likely to mold, and leaves left wilted in heat lose their oil quickly.

For marjoram, cut the stems before the plant flowers. Cut stems with garden shears or a sharp knife, and avoid bruising the leaves. The Washington State University drying publication advises that herbs should not lie in the sun or sit unattended after harvest, so bring the cut stems indoors as soon as they are picked.

Clean the harvest before drying. Shake off soil and insects, and rinse the stems under cool running water only if they are visibly dirty. The Oregon State guidance describes rinsing under cool running water and then shaking off excess moisture before drying. Pat the leaves with a clean towel so no visible water remains.

Method one: air drying bundles indoors

Air drying is the simplest method for marjoram. Tie small bundles of four to six stems together with string or a rubber band, then hang them upside down in a warm, dry room with good air movement. The Purdue publication advises hanging herbs away from the sink and the stove, and the Washington State publication recommends a dry, well-ventilated area until the moisture evaporates.

The Wisconsin publication gives a general time for air drying, saying the herbs should be left to hang until the moisture evaporates, generally two to four weeks. The Oregon State guidance states that “Air drying outdoors is often possible; however, better color and flavor retention usually results from drying indoors.” Outdoor air drying can work in a dry climate, but dew, rain, and direct sunlight can all reduce quality. Indoor drying keeps the leaves away from those conditions and protects their color.

Another option is to lay the stems on screens or on paper towels in a single layer. The Purdue publication describes a method that uses a paper bag punched with holes, which allows air to circulate around the bundle while catching loose leaves. Paper towels or screens are also used for laying out leaves, and they need to be changed when they absorb moisture.

The leaves are ready when they crumble easily between your fingers and the thin stems snap when bent. Check the bundles regularly during the drying period, because the time depends on humidity and room temperature.

Method two: dehydrator drying

A dehydrator gives faster and more controlled results, especially when the air is humid. The Oregon State guide advises pre-heating the dehydrator with the thermostat set to 95 degrees Fahrenheit to 115 degrees Fahrenheit, and it notes that areas with higher humidity may need temperatures as high as 125 degrees Fahrenheit. Washington State University describes dehydrator drying as “a fast and easy way to dry high quality herbs because temperature and air circulation can be controlled.”

Spread the leaves or small sprigs in a single layer on the dehydrator trays so air can reach every surface. The Oregon State publication gives a drying window of one to four hours and says to check periodically. Use the manufacturer’s instruction booklet for the specific model, because airflow and tray spacing vary between dehydrators.

The Wisconsin publication recommends a dehydrator for high-moisture herbs, but it lists marjoram among the sturdy herbs suited to air drying. For marjoram, a dehydrator is a good option when you need quicker results or when the room is humid. It is not required for a good result.

Testing dryness and storing dried marjoram

Dryness is the main quality check. Both the Oregon State and Washington State publications describe the same signs: the leaves crumble when rubbed, and the stems break when bent. If the stems bend rather than snap, the herb is not yet dry, and it should be left to dry longer. Leaves that are still soft are more likely to develop mold during storage.

Once the leaves are dry, strip them from the stems over a bowl or a sheet of paper so that small pieces of stem do not enter the jar. Store the leaves in an airtight container, and keep the container in a cool, dark, dry place. The Oregon State guidance says dried herbs can keep for up to a year in those conditions, and it recommends using them within six months to one year for the best flavor. Label each jar with the herb name and the date.

Practical steps to dry marjoram

Harvest stems in the morning after the dew dries, before the plant flowers.
Remove any damaged leaves and shake off soil or insects.
Tie small bundles and hang them upside down in a warm, dry, ventilated room, or lay the stems in a single layer on screens or paper towels.
If humidity is high, dry the leaves on dehydrator trays set between 95 and 115 degrees Fahrenheit.
Check for crumbling leaves and snapping stems, then strip the leaves from the stems.
Store the leaves in an airtight, labeled jar in a cool, dark, dry place.

What we could not verify

The sources reviewed here describe general methods for drying herbs, including marjoram, and they do not test marjoram against each method. The time ranges and temperature ranges are the figures the publications give, and they may not suit every room or dehydrator. This guide does not present a drying trial as evidence for any of its figures.

What the sources do not say

None of the publications reviewed here gives a separate drying time for marjoram. The Oregon State dehydrator window of one to four hours applies to herbs in general, and the two-to-four-week air-drying figure from Wisconsin is also a general figure for herbs. The sources do not state how long marjoram keeps its flavor specifically, beyond the general one-year figure for dried herbs.

The publications do not compare the flavor of air-dried marjoram with dehydrator-dried marjoram, and they do not describe the best bundle size for a given room. Those points are left to the reader’s own judgment and experience.
