Origanum majorana
herbA sweet, mild perennial herb closely related to oregano but with a softer, more nuanced flavor. Used extensively in Mediterranean cooking — particularly French, Greek, and Italian — for poultry, lamb, egg dishes, and soups. Sweet marjoram is slightly more delicate than oregano and less bitter. It grows as a tender perennial (zones 9 to 10) or annual in colder climates.

When to Fertilize
Light compost at planting; minimal feeding through the season
Fertilizer
Minimal fertilizer; lean soil produces more aromatic, flavorful leaves
Start indoors 6 to 8 weeks before last frost. Seeds germinate slowly — be patient. Transplant after danger of frost passes. In zones 8 and colder, grow as an annual or bring containers indoors for winter. Marjoram prefers lean, well-draining soil — rich or wet soil dilutes flavor. Pinch tips regularly to encourage bushy growth and delay flowering. Flavor is most intense just before flowering.

Water blast; insecticidal soap; introduce parasitic wasps
Mist foliage in hot dry weather; neem oil every 7 to 10 days if needed
Excellent drainage essential; raised beds preferred; water deeply and infrequently
Reflective mulch; spinosad spray if severe
Harvest young stem tips regularly, cutting just above a leaf node to encourage branching. Best flavor just before the plant flowers — pinch flower buds to extend the harvest season. Use fresh immediately or dry by hanging bundles in a warm, shady spot. Dried marjoram retains excellent flavor. Freeze chopped fresh leaves in olive oil for longer preservation.
Contains high levels of vitamin K, iron, calcium, and manganese. Rich in carvacrol, sabinene, and linalool — aromatic compounds with documented antimicrobial properties. Traditionally used as a digestive herb and to relieve headaches. Higher in antioxidants than most fresh herbs per gram.
