🌾 Sow directly in the garden — Greek Oregano is not usually started indoors.
Since this is a perennial herb often direct-sown or started indoors and moved out after frost danger passes, wait until soil warms up completely before transplanting young seedlings into their final positions.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 8.0 before sowing seeds directly outdoors or starting them indoors. As a warm-season perennial herb, you should wait until after the last frost date to plant outside, though some start indoors a few weeks prior for early blooms. Press seeds gently into the topsoil at a depth of about 1/4 inch, as they require light for germination which takes 7 to 14 days.
Space plants 12 to 15 inches apart to ensure good air circulation and bushy growth. While this herb does not need staking or trellising, apply a light layer of mulch around the base to retain moisture without suffocating roots. Water moderately during dry spells; once established, it tolerates low water needs well but benefits from occasional feeding if grown in poor soil.
Watch for spider mites and rare aphids on leaves, preventing issues by ensuring excellent drainage to avoid root rot. Harvest sprigs when the plant reaches maturity, typically around 80 to 90 days after sowing. Snip stems just above a leaf node in the morning when essential oils are most concentrated for the best flavor profile.
