Quick facts: Harvest oregano in the morning after the dew has dried and the aromatic oils are at their highest level. Harvest and prune your oregano plants regularly, but avoid taking more than ⅓ of any individual plant at any given time.
Plan to harvest your oregano plant before it starts to flower, or you will find that the taste is milder or even bitter for some varieties and that the re-growth rate will slow down.
Oregano is a perennial herb and will come back year after year if you treat your plants right.

When can I start harvesting my oregano plant?
Wait for your oregano plant to grow stems that are at least 10 cm / 4 inches tall.
When you harvest your plant at the early stages of development, it is essential only to harvest a maximum of ⅓ of the branches.
Regular harvesting and pruning will stimulate new growth and a more robust, compact plant.
What is the best way to harvest oregano?
My preferred method is to use a pair of sharp garden scissors. Cut the stem at a 45-degree angle and watch the plant grow stronger and bushier.
Avoid pinching the branches with your fingers. You risk bruising the plant, and it is so easy to use a pair of scissors or at least a sharp knife.
Can I harvest after the oregano plant starts to flower?
Yes, of course, you can. But you will find that the taste will be milder and even bitter for some varieties of oregano.
You will also find that the rate of re-growth is much slower when you harvest after the plant flowers.
We pinch or cut the tips on most of our oregano plants to prevent them from blooming.
Bonus tip: Why not let some of your oregano plants flower to help attract pollinators like butterflies and bees.
Do you harvest late in the year?
We always stop harvesting early fall to let the plants rest and prepare to overwinter.
Will oregano grow back after harvest?
Yes, oregano grows more robust and compact when you harvest or prune the plant.
I would even go so far as to say that you must prune oregano for the plant to remain healthy. Untended plants will lose their shape and grow woody stems prematurely.
What is the best way to preserve oregano?
I don’t know which is the best way, but drying oregano is my favorite method to preserve oregano.
But frozen oregano-flavored olive oil cubes come in as a close second.
You can also freeze oregano whole, but I prefer the other two methods.
How to dry oregano
Start by harvesting a bunch of oregano stems. Oregano loses much of its volume when dried, so you must gather at least 10 branches.
Next, rinse and wash the stems thoroughly. Be careful to remove any dirt but also unwelcome bugs and insects.
Now dry the leaves to remove any excess water.
Next, place the stems in a brown paper bag. Put the bag in a dark room with good air circulation. You are looking for dry heat and room temperature works.
The oregano will dry in anything from one to several weeks. Check back now and then.
You will know when the oregano is dry as it will fall off the stem.
When the leaves are dry and removed from the stems, grind them in a pestle and mortar to your desired size and texture.
Pour the ground oregano into an airtight container and store it in a dark cupboard or drawer.
How to freeze oregano
Use your fingers to remove the leaves from the harvested oregano stems when rinsed, washed, and dried.
Use the same technique shown in the video below with the herb tarragon.
Place the oregano leaves in a freezer bag and remove as much air as possible.
Frozen oregano loses its form and texture when defrosted. Make sure you freeze your oregano in portion-sized pieces for easier handling.
How to make oregano-flavored olive oil cubes
Again, remove the oregano leaves from the harvested stems when rinsed, washed, and dried.
The next step is my favorite blend, but feel free to use your spices.
Put a handful of leaves, a pinch of sea salt flakes, and one tablespoon of olive oil in your mortar. Now, use the pestle to grind the content into a paste of your desired consistency and flavor.
When you taste, remember that you are looking for big flavors, as this is a flavor enhancer you add to dishes.
Feel free to add spices if you want.
When you are happy with the taste, pour the paste into an ice cube tray and place it in the freezer. After a day or two, when the cubes are frozen, place them in a freezer bag and put them back in the freezer for later use.
Should I wash my harvested oregano before drying?
You should always rinse and wash your harvested oregano to remove unwanted bugs, insects, dirt, and soil.
Do you eat the oregano stems?
No, the stems tend to be too woody and taste bitter.
But branches are great to use to add or induce flavor in a steamer or as sticks for kebabs on the BBQ.
