oregano just before the plant flowers, or as needed. Oregano is most flavorful right before the plant flowers, so this is the perfect time to harvest if you plan to dry or freeze your herbs. However, you can also harvest small amounts of oregano to use fresh in your kitchen.  Keep in mind that the oregano may taste bitter after the plant flowers, so it's a good idea to harvest the remaining stems before your plant flowers. You can dry them by hanging them in bunches or using a dehydrator. Alternatively, you could freeze them. The best time to harvest oregano is in the morning after the dew dries. The flavor of your oregano will be strongest during warm weather. You can harvest less, but not more. Position the scissors against the stem in a spot that's in between the leaves to prevent damaging the leaves. Place your thumb and middle finger just below the leaves you want to harvest. Slowly run your hand up the stem to pull off the leaves, collecting them as you go. Place the leaves in a clean, dry container for use in your kitchen.  Cut away the bare stem using your scissors.  This is a great alternative for days when you just want a few leaves to season a dish.
