Cuban Oregano is a succulent herb prized for its lemony flavor and ability to thrive in hot climates. Gardeners grow this drought-tolerant plant not just for cooking, but also as an attractive ground cover that repels pests naturally.

🌾 Sow directly in the garden — Cuban Oregano is not usually started indoors.
As a warm-season succulent, start seeds indoors only weeks before your expected last frost date and transplant seedlings outdoors immediately afterward once all danger of cold has passed.
Soil, care & harvest
Prepare well-draining soil with a pH between 6.0 and 7.5 before starting seeds indoors. Since Cuban Oregano is a warm-season crop, wait until after the last frost date to move seedlings outside or direct sow outdoors once temperatures are consistently high. Press seeds gently into the surface without covering them deeply, as they do not require burial. Expect germination within 14 to 21 days under warm conditions.
Space plants 12 to 18 inches apart to allow for bushy growth without crowding. This herb requires no trellising or support due to its low, succulent habit. Water only when the soil feels dry, as it tolerates drought well; avoid overwatering to prevent root rot. Apply a light layer of mulch in summer to retain moisture and suppress weeds while feeding is rarely needed.
Watch for scale insects, mealybugs, or spider mites indoors, treating infestations with insecticidal soap if they appear. Ensure excellent drainage to avoid root rot, though the plant is otherwise very hardy. Harvest leaves and stems starting at 60 to 90 days after sowing by snipping what you need regularly to encourage continued bushiness.
