Harvest Tips
Pick leaves as needed throughout the growing season. Their flavor fades after plants bloom so harvest before flower buds open. Savor oregano’s spicy taste on grilled meats or seafood, sprinkle it onto cooked vegetables, or stir it into pasta sauces. Gather fresh flowers to add to salads. Oregano’s flavor stays strong after drying it. To dry a large amount of oregano, cut stems back to 3 inches (before flower buds open); cut again in the same way in late summer. Dry the stems by bundling them together and hanging them upside down in a dark place with good air circulation. When leaves are dry, crumble them from stems; store leaves in an airtight container. When cooking, if a recipe calls for dried oregano, you can substitute twice the amount of fresh for the same flavorful result.
Harvest Often
Begin harvesting oregano as soon as sprigs are 6 inches tall. Harvest stems frequently to prevent the plant from producing flowers and to keep it from forming woody plant stems. Oregano tolerates shearing well; don’t hesitate to cut plants back by half their stem length to encourage them to produce fresh, flavorful foliage.
Planting Partners
Oregano grows well in full sun, making it a good choice for planting alongside other sun-loving herbs like rosemary, parsley, sage, and thyme. Grow these herbs together in a planting bed, alongside perennials in a mixed border, or in a raised bed. Herbs also thrive in containers of all shapes and sizes. Have fun with repurposed planting vessels for herbs. The diverse textures and subtle color variations of herbs make them exceptionally useful in the garden design. A trio of oregano plants planted near a boisterous planting of hollyhocks and daylilies gives the eye a quiet place to rest amid the color and interest of the combination. Low-growing oregano forms a wide mound of foliage, blanketing nearby soil and smothering out weeds.
Winter Cover
Oregano is marginally hardy in Zone 5. Help plants overwinter by covering them with a winter mulch of evergreen boughs or straw applied after the soil freezes in late fall. Remove the mulch as soon as growth resumes in spring. Oregano can also be grown inside during winter. Transplant plants from the garden to a generous container in early fall. Place in a sunny window during winter and water when the surface of the soil is dry.
