Sweet Marjoram(Origanum majorana)
Light requirements Full sun.
Planting Space 12 inches apart.
Soil requirements Plants grow best in rich, well-drained soil. Soil pH should be 6.7 to 7.0.
Water requirements Keep soil moist after planting until plants are well-rooted. Once established, sweet marjoram prefers slightly dry soil. Water only during times of drought. In containers, irrigate whenever the top inch of soil is dry.
Frost-fighting plan Sweet marjoram is perennial in zones 9 and 10. Plants may survive the winter in zones 7 and 8 if plants are mulched heavily after frost. In colder zones, take stem cuttings to start new plants for overwintering on sunny windowsills. Established plants cannot survive even light frosts (above 32º F). Use a frost blanket to protect newly planted seedlings from late spring frosts or prolong the growing season in fall.
Common issues Sweet marjoram can suffer root rot in poorly drained soil.
Growing tips Clip stem tips often to promote branching and bushiness. Clip flowers to encourage plants to keep producing flavorful leaves.
Harvesting Pick leaves at any point in the growing season, although flavor is most intense just before plants bloom. Flower buds are edible. To harvest, snip leafy stems to the length you desire. Don’t cut plants flush with soil; allow a few inches of stem to remain. Stems will produce new growth.
Storage Put a few stems in water at room temperature to enjoy fresh clippings for a few days. Wrap unwashed stems in a barely damp paper towel and slip into a plastic bag. Store stems in the lowest part of your refrigerator. Use within 4 to 7 days. Dried sweet marjoram tastes nearly the same as fresh.

Sweet marjoram, a member of the mint family, boasts pale green leaves and a mild, sweet flavor similar to the oregano plant. Loaded with Vitamin K, marjoram helps diminish the risk of blood clots and reduce blood pressure and blood cholesterol levels. Marjoram is also a good source of manganese, which helps strengthen bones, collagen, and connective tissue. In the form of an herbal tea, sweet marjoram leaves may also stimulate the immune system. Chefs who season their dishes with sweet marjoram add the herb toward the end of the cooking process so the seasoning’s mild flavor isn’t diluted.
